Fume hoods protect against dangerous or poisonous gases, vapours, or airborne particulates by providing safe ventilation. A chemical fume hood is primarily intended to protect the user or the environment outside the hood in laboratory and production settings, but it can also be used to protect the materials or experiment within the hood.
Ducted fume hood designs link to a remote exhaust system to safely ventilate outside the building. Ductless fume hood arrangements filter and recirculate purified air using a built-in fan and filtration system. Activated carbon filters for the elimination of non-hazardous, nuisance odors are available as add-ons for laboratory fume hoods. To eliminate tiny particles and germs, HEPA or ULPA filters can be added to a light duty fume hood. For volatile or flammable applications, explosion-proof fume hood designs are offered. When floor space is restricted, a wall-mounted canopy fume hood gives you more options.
International regulatory bodies have extensively regulated the sampling and dispensing of substances such as chemicals, excipients, actives, solvents, and other chemical entities used in the food, cosmetic, pharmaceutical, and biologicals industries. This part of the process necessitates substantial design and qualification inputs. ISOVAX designs and manufactures open fronted and close fronted downflow booths for these industries.
For dealing with bio/pharmaceutical samples, medical devices, semiconductor components, and other sensitive materials, Horizontal Laminar Flow provides a particle-free environment. Its rear-unted fan/filter unit continuously circulates HEPA-filtered air to wipe away contaminants. The Horizontal Laminar Flow unit (HLAF) from Isovax delivers a cost-effective work environment that satisfies the most rigorous contamination regulations.Isovax’s VLAF combines a number of our most sophisticated systems into a cutting-edge workstation that eliminates articulate airborne contamination.
ISOVAX Dynamic Type Pass Boxes allow components, tools, and other work items to be passed into and out of the clean room while minimizing traffic and contamination. The unit functions as an air lock, keeping ambient air from entering the clean room and clean air from leaving. Because a continual flushing of the working area by a unidirectional, vertical, and ultra-filtered airflow ensures full product protection, the Dynamic Pass Box permits operating in sterile and particle-free circumstances.
The ISOVAX Pass Through Hatch is meant to reduce traffic and contamination into the clean room by allowing parts, tools, and other work items to be transferred into and out of the room. The unit functions as an air lock, keeping ambient air from entering the clean room and clean air from leaving.
Powder dispensing booths are used to keep hazardous powder and dust emissions to a minimum during powder dispensing, product sampling, or bag dispensing, for example, without endangering the operator or the environment. The downdraught keeps dust from rising into the operator’s respiratory zone during weighing and dispensing activities. The air driven downwards is removed at the booth’s lowest level of filtration, where dust particles are retained at each level of filtration before being re-circulated back into the booth’s air stream.
Air showers are specialized enclosed chambers that are used to decrease particle pollution in cleanrooms and other regulated settings. High-pressure, HEPA- or ULPA-filtered air is used in air showers to remove dust, fibrous lint, and other pollutants from persons and object surfaces. The quantity of airborne particles introduced is reduced when surfaces are “cleansed” vigorously before entering clean surroundings.
When suitable standards and procedures are followed, Biological Safety Cabinets (BSCs), also known as tissue culture hoods, are meant to provide human, environmental, and product safety. A vented cabinet for people and environmental protection is classified as a Class I cabinet. These do not provide product contamination protection, which severely limits their applicability. A ventilated cabinet for personnel, product, and environmental safety for microbiological operations or sterile pharmacy compounding is classified as a Class II cabinet. An open front with inward airflow (people protection), downward HEPA-filtered laminar airflow (product protection), and HEPA-filtered exhaust air are all features of Class II BSCs (environmental protection). A Class III cabinet is defined as a completely enclosed, ventilated cabinet with a leak-tight structure and attached rubber gloves for performing cabinet activities. Glove boxes are another name for Class III biosafety cabinets.
