Vacuum Oven – One Tool with Numerous Benefits

When it comes to a regular oven, it is only capable of heating function.

But the Vacuum Oven takes the properties of the oven to the next level.

Vacuum oven consists of a special pump which also supports the drying function in addition to heating.

How does it work?

The vacuum drying forces the pressure in the narrow gaps and in the tubes to decrease, which enables the moisture in the gaps to evaporate faster.

Moisture evaporates much faster, because the vacuum environment reduces the pressure, and that is why boiling points become much less. And this makes it a very useful tool.

Where can it be used?

• Chemical fields
• Biological related industries
• Pharmaceutical and medical field
• Agricultural research
• Environmental testing etc

What makes a vacuum oven better than a regular oven?

• Less time required in warming up things.
• Temperature is controlled in high precision with turbo-drying
• Drying heat-sensitive delicate things, like food, cosmetics, powders etc is safe in it

Applications of vacuum oven are:

• Removal of pyrogens, these are bacterial substances in utensils which causes fever
• Determine the moisture content in foods etc
• Sterilization, purification of solids
• It is used for classification of solids too in industries
• Baking
• Drying Etc.

Several advantages of vacuum oven:

• Liquid substances will not be expelled, because in vacuum conditions the boiling point of substance will reduce to much extent. And hence, heat-sensitive can easily be put in a vacuum oven.
• When it comes to drying power and granular samples, it is always a struggle. But the vacuum drying method works effectively and helps drying such substances easily in much less time.
• Mechanical parts and porous samples etc are made of very complicated substances and direct heat can affect their chemical structure and also affect the usefulness. But vacuum drying keeps all that safe, and dry them in a convenient way.
• Because it works on much less pressure, so the possibility of explosion, oxidation, combustion, inflammation etc is completely eliminated.
• Your powdery samples will stay intact because there is no flowing air method used for drying.

Final words: 

Vacuum oven is one of the legendary tools, which has all the capabilities to help us and make our work easier, when it comes to drying and baking and all.

But every technology has its dangerous effects too, so use it with precautions like knowing the right temperature and wearing gloves etc.

If you do that, you will have an amazing experience in your work.

Some Popular Applications of Ultra Low Temperature Freezers

It has been ages since the concept of preserving perishable items by deep freezing and flash freezing became popular. Today, if you are looking to keep organic matter of any kind safe for long time, ultra-low temperature freezers are the best and first choice for you. Here is a list of common applications where these freezers are being used all across the world.

1. Meat and Seafood Storage: Meat and seafood are among some of the most popular food items these days. But the inherent nature of these products means that they spoil easily because of bacteria and protozoa in it. For seafood, there is also the distance factor which means that only frozen fish or prawns ca be shipped over long distances.

2. Pharmaceutical Industry: Medical science has made a lot of progress in the last few decades.

Food preservation is one of the most widespread uses of freeze dryer equipment. The food materials that has undergone this kind of preservation process can be stored for longer durations and also remains free from any harmful effects of artificial preservatives or sweeteners. For any person who is starting to learn food preservation, Yatherm freeze dryer is simple and easy to use machine that can deliver great results with minimal investment in financial terms and efforts involved. Below are a few of the most important considerations that must be observed when a freeze dryer is to be used for food preservation.

• Do not mix meat with any other kind of food. Meat should always be freeze dried on its own. Any kind of cross contamination can lead to growth of e coli or other harmful bacteria in the food an must be prevented in all situations.

• Do not try to freeze dry large size meat cuts and pieces. The freeze-drying process while very effective has its own speed and limitations. If rather large pieces of meat are processed, they might not be preserved properly and there is also the risk of rehydration not working which means when food is to be consumed, meat will have a leathery taste and texture which is rather unpleasant.

• Do not try to dry food items with high fat content. Food with high fat content will always react adversely to any attempts to freeze dry. Something like butter or cheese has very high fat content and any attempt to freeze dry it will cause layers of fat to accumulate on the chamber which will take hours upon hours to be cleaned.

• Check before your try to freeze dry high sugar foods. Freeze drying food items which are naturally sweet, like fruits and berries can be easily processed though larger food items will take longer. That is why pineapple slices are freeze dried instead of full pineapple. On the other hand, fruit juices and jams, even if derived using no artificial sugar or additives will not freeze dry well because of the very high concentration of sugar which causes adverse chemical reactions when exposed to low temperatures.

• Ensure foods with similar tastes are freeze dried together. Mixing food items with different tastes is a cardinal sin with regard to food preservation. Simply because the taste of different items can only be locked with different levels of processing. Mixing the items will cause taste crash with some items completely losing their taste while others are freeze dried inadequately and risk early spoilage.

• Overfilling the freeze dryer must be avoided. The machine has its stated capacity and if any attempt is made to over stuff it with items for whatever reason, the results can be from anywhere like improper preservation to total item spoilage and even equipment damage. Always ensure that machine is only loaded to its stated capacity and multiple cycles should be used if large amount of food items need to be preserved. Patience is the key in such cases!

Summary: Your personnel and lab environment could fall prey to accidental contamination. However, you can easily nip the problem in the bud with a biosafety cabinet.

Like it or not, but laboratory operations do expose you to different biohazards time and again. In fact, the very same biohazards, if not taken care of in a timely manner, could lead to some serious repercussions. Therefore, it is imperative that you get hold of a biosafety cabinet at the earliest and ensure that your facility isn’t unknowingly exposed to harmful and deadly outcomes. In fact, investing in a good BSC is a must, more so, if you care for your personnel. After all, it is your responsibility to safeguard them and keep the environment safe. Protection or the lack thereof could leave them susceptible to contamination. And that’s because viruses, bacteria, and toxics could be at play.

Anyway, if and when you do decide to invest in a biosafety cabinet, make sure you refer to this checklist and then zero in on one:

• For starters, the BSC should be in tandem with your lab space, i.e. it should fit well
• Secondly, you ought to choose the appropriate class, one that caters to your requirements
• Last but not least, it’s important that the equipment you choose is reasonably priced. That said, you cannot let quality take a backseat. So, look for a manufacturer who strikes a balance.

Let’s say, you want to save the laboratory personnel against biological hazards. In this case, it makes sense to go for biosafety cabinets Class II. These cabinets have HEPA filters and pre-filters and can therefore ensure that you get to benefit from filtered air. As a result, both users as well as products are considerably safe. What also makes class 2 cabinets your best is the fact that these could offer protection to samples, keeping airborne contamination at bay. So, if you have a microbiology laboratory, you should not have to think twice before investing in this one.

Now, as a first-timer, you should also know that every class has further classifications, and it is only after knowing about them in depth can you take your pick. Class 2 cabinets for instance vary depending on of course features, but also on the basis of construction and applications.

• Class II, Type A1 should only be considered if there are lower risky agents at play. These cabinets can offer suitable protection against mild chemical and nuclear energy reactions, but that’s about it. Using the very same cabinets for biologically hazardous chemicals or radioactive chemical reactions is a big no-no. For these hazards, it is strongly recommended that you rather go for Class II, Type A2: biosafety cabinets.

• Coming to the next cabinet, the Class II, B1 is appropriate for Microbial toxins reacting with dangerous chemicals in lesser amounts. The B2, on the other hand, fits the bill quite perfectly if your microbiology lab is susceptible to dangerous chemical reactions & biological agents such as fungus, bacteria, and viruses.

When all is said and done, you can only make the best choice if you know your needs one and then choose the cabinet that offers maximum protection at of course the lowest cost.

What Is Clean Room Pass Box Definition?

These are room systems which determine the entry of particles into the room, where the amount of formation is designed to be minimized to the minimum limit of retention, where the concentration of airborne particles used and the desired parameters in scope are controlled as required by temperature, humidity and pressure.

Staff Entrance Room, Clothing Area & Doorway Room: It is the place where the staff wears their aprons, face masks, gloves and shoes and wears the clean room clothes which are determined to vary from gallons. The amount of clothes, the amount of staff is determined by the process. As the garment enters the clean room, the clean room air strikes, depending on the outside area outside the clean room, due to the pressurization of the room and prepares the transition to the other room. The cleaning level of this area will generally be lower than other cleanroom areas.

Assembly Packing Room & Data Room: This is the place where the product is prepared or made. This area is generally constructed at a higher pollution control level than the personnel entrance chamber and is at a higher pressure level than the personnel entry chamber and is the filling room preconditioning area. When you open the door from the front room to the processing area, it means that clean room air strikes your face. Protocol levels are higher in this area and include the frequency of cleaning, restrictions on allowed equipment and vehicles, and controlled product transfer in and out.

Filling Area & Critical Process Area: If part of the cleanroom process requires a higher level of contamination control, an additional chamber can be added or a vertical or horizontal flow bench can be added. Again, this area will be at a higher pressure than adjacent areas. Usually, sensitive products include mechatronic systems in the body, stem cell laboratory systems.

Clean Room Specifications:

Clean Room Panel System; 60 mm thick, internal insulation with EPS material filling, B class flammability class hygienic panels.

In order to achieve the desired pollution class, the quality of the materials and application teams to be used in clean room design is very high, as well as the quality of testing, measurement and calibration to be performed during and after the application phase.

LAMINAR AIR FLOW HOOD: HOW TO WORK & PURPOSE

How Does A Laminar Air Flow Work?

The laminar air flow hoods are electro-mechanical equipment used to maintain sterile conditions. The proper functioning of these equipment is evaluated by applying tests and assigning a rating. The air flow hoods are cabins maintaining sterile conditions in place by passing the air through a filter high efficiency air (HEPA). There are horizontal and vertical type.

Horizontal laminar flow hoods are generally manufactured in prismatic form with a single free face (the front) that gives access to the interior, where the work surface is located. The air filter in this type of laminar air flow is located at the back. Its main applications are:

• Preparation of ophthalmic solutions.
• Preparation of sterile and urological topical solutions.
• Mix of food and formulas for babies.
• Ideal for clinical laboratory tests.
• Preparation and crop readings.
• For blood fractionation.

On the other hand, in the vertical laminar flow hoods, the HEPA filter is installed at the top of the hood, so that the air flow is unidirectional and moves through parallel vertical lines. These types of bells are considered safer than horizontal ones. Within this classification are the biological safety bells which are used in:

• Management of viruses, bacteria, etc.
• Useful in very low concentrations of contaminants.
• Protection level for group 1.2.
• Protects the user, the product and the environment.

Elements of a Laminar Air Flow:

The laminar air flow, also known as the laminar flow hood (cabinet) or tissue culture hood, keeps the atmosphere of the interior volume of your work area free of dust. Normally, this area is delimited by stainless steel sheets, except in its front part that usually has one or two guillotine tempered glass doors.

The air flow from a fan passes through a high efficiency HEPA filter, capable of not allowing particles larger than 0.3 micrometers to pass, and metro logically classified to a minimum efficiency of 99.97% according to European standard EN1822 H12 a minimum efficiency of 99.999% can be reached in a HEPA filter that complies with the European standard EN1822 H14.

The fan speed is regulated by an electronic controller so that the air speed is reached, and therefore the appropriate pressure, necessary for the air flow in the work area to be laminar. The pressure value is indicated on the pressure gauge installed outside the cabin.

If it is necessary that the atmosphere in addition to being dust-free, also be sterile, an ultraviolet lamp, mounted inside the chamber, is incorporated as an option.

In case it is necessary to work with toxic products, the hood incorporates a second HEPA filter installed in the air outlet, to avoid the emission of polluting products.

What Is The Purpose Of Laminar Flow Equipment?

A laminar flow equipment basically constitutes a space, which, by means of a specific treatment of the air, allows working in an area with a strict control of non-road particles.

It should be clarified that the purpose results in the protection of the product and / or process but not the operator, which should be considered with what is going to work in a way that allows the selection of appropriate equipment, without risks to the operation. For the personnel that operates.

Laminar flow equipment, in this case, contributes to the recirculation of clean air in the environment where they are, since they have a continuous work of air renewal. Let’s not forget that they take it from their environment, filter it and return it to the environment with an extra stage of absolute filtration, and this process is constant.

Laboratory hot air oven is equipment that is highly prized for being used in pharmaceutical laboratories as well as other material testing labs. The regularly improving awareness about the dry sterilization process among professionals associated with laboratories and research centers, the demand of laboratory hot air oven has been increased in the last few years.

Discuss the Principle Here On Which It Actually Works

A gravity air convention found in an electrically heated chamber is primarily responsible for the working principle of the laboratory ovens. The heat created in the chamber is a result of the installation of various advanced components in the machine. The presence of temperature preset function, PT 100 sensors, PID controlled, automatic control unit and two jacket designs make sure that the machine works in the optimum possible way by allowing it to get the normal temperature back when the material testing is done.

The primary job of designing this heating equipment is to simplify the process of dry sterilization while conducting the pre-treatment of different types of materials such as plastic, rubber, etc.

The flow of air occurs in a forced circulation manner to distribute the heat equally in every corner inside the chamber. As soon as the air becomes hot, it turns into very light and starts moving in the upward direction.

At the top of the chamber there is a fan, which pushes this air back towards the bottom direction. This results in generating the needful circular motion inside the chamber while allowing the cabinet to witness a steady circular flow of the air. The process is done inside the cabinet actually helps professionals to create the maximum possible temperature.

Make sure not to take your articles out of the cabinet immediately right after getting it sterilized. Wait for returning the hot air oven instrument to its normal temperature in order to avoid any discrepancies during the process.

Major Benefits of Installing Hot Air Ovens

• Wet sterilization is not perfect for all the articles/materials. You can use this instrument for different materials like powder and oil, which are more likely prone to getting spoiled if they are wet sterilized.
• No need to dismantle the articles since it is exposed to an environment which contains the high temperature for the good time.
• Dry sterilization is found to be perfect even for the metal equipment, which is more likely to be corroded during the wet sterilization.
• Operator can also use the dry sterilization.

Take These Precautions before Beginning the Process

• Avoid keeping the article directly on the floor due to the high temperature from where it is taken out.
• Make sure to wrap the glass apparatus with a clean and dry cloth.
• Every chamber comes with a prescribed limit. So, check the instructions twice before loading the chamber.
