Hot Air Oven – Working Principle Along With its Amazing Benefits

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.

Spectrophotometers and Their Two Major Classes

A spectrophotometer, also known as UV spectrophotometer, is a type of equipment primarily used to study the electromagnetic spectra in lab. It is more detailed and precise than the wider term electromagnetic spectroscopy where spectrophotometry is focused on the near-infrared, near-ultraviolet and visible light. The implementation of the time-resolved spectroscopic techniques is common in electromagnetic spectroscopy while spectrophotometry doesn’t support them.

Spectrophotometry is concerned with determining the intensity of light as a function of the color. To be more precise, it helps to measure the wavelength of light. Measuring the spectral bandwidth and liner range of production are the major traits of spectrophotometers. Although, the primary application of this equipment is to measure the light absorption, it can also be used to calculate diffuse or specular reflectance.

Apart from handing the responsibilities in the field of physics, UV spectrophotometers are also designed with dealing other scientific fields like molecular biology, biochemistry and chemistry. It also finds its place in a range of other industrial applications that include printing as well as forensic examination.

Classes of Spectrophotometers

UV VIS Spectrophotometer

Ultraviolet visible spectrophotometers, also known as a UV spectrophotometer or a UV Vis spectrophotometer, are used to measure the optical properties of samples in the ultraviolet. The primary responsibility of UV Vis spectrophotometers is to measure the wavelength ranges of light that passes through a sample and how it is absorbed.

This equipment could help to scan either variable or fixed wavelengths and are primarily available in two classes – single and double beam spectrophotometer.

Although both the configurations share the same basic principles, V-Vis spectrometers differ majorly from the first DUs.

Double-Beam UV-Vis Spectrophotometers

In double beam UV-Vis Spectrophotometers, the division of energy that comes from the light source is taken place into two direction with a half mirror, while allowing the one to pass through the reference side and the second one through the sample side making sure that both gives the reading simultaneously.

In general, these instruments are common in clinical and research laboratories where the functions like wavelength scanning, kinetics, quantitative analyses as well as DNA and Protein analysis are taken care of.  Some of the major features of the instruments include sample changers, self-test diagnostics for GLP instrument performance validation, method storage, on-board software and long lamp life. Automatic sippers, tube adaptors and temperature control are the specific application needs for which optional accessories also come in the market.

UV Spectrophotometer Vs Visible Region Spectrophotometer

The utilization of visible region spectrophotometer is common in colorimetry science, while the utilization of a UV spectrophotometer is majorly concerned with determining UV-visible wavelengths. The data obtained through colorimetry is a major prerequisite of textiles vendors, printing companies and ink manufacturers.

Ultraviolet-Visible (UV spectrophotometry) is designed to conduct the spectroscopy of photons in the UV-visible region. This clears that only the visible and adjacent ranges of light come into action for the task. The instrument used in the process is the UV spectrophotometer instead of opting for a visible region spectrophotometer.

Install a Pass Box to Prevent the Contaminated Air in Your Clean Room

Important Q&A’s for Hospitals with Morgue

Storing Dead Bodies? Three Q&A’s you should review.

If your hospital storing dead bodies, Are you using the correct Mortuary cabinet for your hospital? Here are few questions & Answers which will give you more clarification on the temperature range of Mortuary cabinet.


Q: What is the temperature range of Mortuary cabinet?

A:  As per the international standards temperature range of a mortuary cabinet is 2 to 6 degree Celsius. You need a quality controller and thermometer to monitor the continuous temperature of the cabinet chamber. For accurate temperature inside the cabinet you must have a quality thermocouple dipped in glycol filled bottle instead of placing it in air. Temperature of cabinet should be accurate to avoid any kind of dead body decay.  Air fixed thermocouples are not accurate in comparison of glycol filled bottle because dipped thermocouple provides the temperature of liquid glycol where as air heaters provides temperature of air. Mortuary cabinet controller must have buzzer alarm for upper and lower limit of set temperature.


Q:  What type of dead bodies you store in your mortuary cabinet?

A:  There is many kind of dead body which is kept inside the mortuary cabinet. India is a nation with huge population with huge number of deaths per day.

There are few dead bodies which undergo the burial and physical disposal within 24 hours after death. We don’t require mortuary cabinet for these types of dead bodies because of lesser chances of body decay.

In case of accidents police examination is must and dead bodies are kept inside the mortuary cabinet for few days which is less than a week.

Unidentified dead bodies & soldiers dead bodies during the war are kept for long time without burial and physical disposal needs to be kept inside the Mortuary cabinet. You cannot store dead bodies for more than a week at 2-6 degree Celsius temperature. After a week time cadaverous starts decaying at a very fast rate 7 to maintain hygiene we cannot store the cadaverous  in mortuary cabinet.


Q: What is the difference between mortuary cabinet and Mortuary freezer?

A:   Mortuary cabinet and Mortuary freezers are used to store cadaverous in hospitals, Railway Station & Army. There is a big difference between both the units operating temperature.

  • Mortuary Cabinet (Mortuary chamber) — Temperature Range – 2 to 6 degree Celsius
  • Mortuary freezer – 0 To (-10 degree Celsius)

Preservation of body for long time is known as mummification in past time but these days we are using cooling Mortuary Freezer for preserving the body. Lower temperature saves the body from microorganism decay.

Still you have any doubt about Mortuary cabinets feel free to contact us any time.

Q: Can we purge Nitrogen gas in Box furnace?

A: NO, purging any gas inside the chamber is not possible. For gas treatment there is a new kind of furnace and we call it atmospheric furnace. There is a huge difference between box furnace and atmospheric furnace.


Q: What is Atmospheric Furnace?

A: This type of furnace is specially designed for gas purging and vacuuming before gas transfer into the chamber. Atmospheric furnaces are fully sealed from all side of the chamber so that it can maintain the vacuum and gas pressure inside the chamber. This furnace is used for those substances which can easily undergo the oxidation while heat treatment.

After closing the door we start vacuum pump and creates vacuum inside the chamber. In full vacuum condition we purge the nitrogen gas inside the chamber and creates inert atmosphere in muffle furnace. After Purging of nitrogen gas we start the heating the muffle furnace chamber.


Q: Can we purge Nitrogen gas after reaching the set temperature?

A: Purging of Gas and vacuuming is not possible in hot environment inside the chamber. Nitrogen gas is colder than Air and it can give thermal shock to heating elements which can damage the heaters and interrupt our operation. It is always recommended to purge nitrogen gas inside the chamber prior heating the chamber.


Q: What is the Difference between Tube furnace and Box furnace?

A: Tube furnace is generally used for chemical synthesis under inert atmosphere condition where box furnace is used for heating and ash content measurement.  All tube furnaces are atmospheric furnaces and box furnaces are heating muffle furnaces.
