Yatherm Biosafety cabinets (Biological Safety Cabinet) II is a steel cabinet covered from all five sides. This cabinet is specially designed to save the user from all kinds of biological hazards. Our Biological Safety cabinets are equipped with HEPA filters and Pre-filters to provide filtered air. Yatherm’s environment-friendly cabinet has an easy and economical setup with a plugin-use facility. Our Class II biological safety cabinet provides a safe environment for users and products.
Most Importantly HEPA/ULPA filters are used to trap the particulates & contaminated hazardous agents. These Filters are selected for the filtration of chemical powders which are manufactured according to the ASTM standards. This is the advantage given by HEPA filters and Pre-filters with air circulation in the workspace.
Biosafety cabinets are reckoned for providing downward airflow and recirculation of airflow which gives a safe environment to the User and product. We offer biosafety hoods in microbiology labs and pharmaceutical industries for drug preparation & chemotherapy testing.
Classification:
Class II biosafety cabinets are classified based on their features, construction, international standards, & application It is divided into four standard categories detailed descriptions are given below.
Class II, type A 1: This class of biosafety cabinets is designed for those rooms that don’t have the facility of ducting. Type A 1 can be used for lower risky agents for mild chemical reactions & low nuclear energy reactions.
Classification of the Biological Safety Cabinet is done based on airflow and which is measured in feet per minute & percentage of re-circulation and exhaust. This class of biosafety cabinets has an inflow velocity range of 75 ft per minute to 80 ft per minute. Recirculation takes place 4-5 inches above the working surface and exhaust is in the downward direction. The re-circulation of air through the HEPA filter is 70% of the total air re-circulates inside the chamber and the remaining 30% exhaust downwards with the pressure of the blower.
We don’t recommend this type of biosafety cabinet for biologically hazardous chemicals or radioactive chemical reactions.
Class II, Type A2: This type of biosafety cabinet is specially designed with a ducting facility for 70% of air must be vented. Most importantly 30% of the total air re-circulates inside the working area. These types of biosafety cabinets can be used for biologically hazardous samples and vigorous chemical reactions.
Type A2 is designed with an airflow range of 100 feet per minute to 120 feet per minute. A2 cabinets contaminated area for testing of samples under positive pressure are always surrounded by Negative pressure which can be seen in the differential pressure manometer. The remaining construction of the biosafety cabinet will remain the same.
Class II, Type B1: The Type B1 cabinets provide a minimum of 100 feet per minute velocity. This cabinet is the advanced version of the Type A1 cabinet which has a ducting facility & 30% air exhaust directly from the working chamber passing through the HEPA & Prefilters. 70% of the air is re-circulated inside the working area of the cabinet. This cabinet is suitable for Microbial toxins reacting with hazardous chemicals in low quantities. An atom that has excess nuclear energy is known as a radionuclide and most importantly radionuclides are very much essential for the microbiology laboratory.
Class II, Type B2: This cabinet is designed for 100% exhaust through a proper ducting facility. This cabinet has no air re-circulation and is dedicated to hazardous chemical reactions & biological agents like fungus, bacteria, and viruses in the microbiology lab. We design what you ask and we deliver with perfection at a reasonable price.
Features:

Operating Principle:
Biosafety cabinet II works on the principle of clean airflow passing through the HEPA filter to exhaust by duct and re-circulation of air inside the working area. Downward Vertical airflow passes through the HEPA filter to protect the sample from contamination. Re-circulation of air saves the user from hazardous chemicals/ microorganisms & air exhaust through HEPA filters saves the environment.
Construction Details:
The Biosafety cabinet is designed with Outer Mild steel powder-coated construction with inner complete SS 304 grade. It has a double-walled construction with proper insulation and airflow. It comes with a base cabinet or without a base cabinet have multiple shelves & lockable door.
Blower Assembly – 1/3 HP motor which runs on Single Phase has 1440 RPM motor with Capacity of 1000 CFM & Pressure 30 mm WG.
Exhaust Assembly – Capacity of 300 CFM & ducting by a Stainless steel pipe have a diameter as per user requirement.
Illumination– We use Philips Illumination light with 700-1000 Lux which illuminates the working table including UV light which is used for cleanliness within the equipment.
Noise level– Yatherm Biological safety cabinets are designed with low noise levels most importantly it is less than 55 Db.
