Servicing side glass with ports for service taps installation.

Motor blower: direct coupled motor, electronic speed controlled to maintain a constant laminar air flow of 0.45m/sec, and compensate for a partially clogged filter up to a maximum plenum pressure of 40 mm of water.

Re-circulating and extractor fans: the ‘S’-Series are supplied with single centrifugal fan, whilst models of the ‘D’ Series with double centrifugal fan (main and exhaust) to provide complete operator, product and environmental protection.

Front window: electrically operated vertically sliding safety glass sash window.

Work surface in stainless steel AISI 316L consisting of sections (or in one piece upon request) which are easily removable for carrying out routine cleaning and/or autoclaving sterilization procedures closed or perforated on request.

Rear wall in stainless steel AISI 304 L, designed to conform to requirements and pass the “cleanability test” according to EN12469:2000.

External structure in epoxy powder coated cold-rolled steel for excellent corrosion resistance to the attack by aggressive common chemicals.

Class III laminar flow cabinets are required for work involving known human pathogens and other BSL-4 materials. Class II laminar flow cabinets are used for handling potentially hazardous materials such as primate-derived cultures, virally infected cultures, carcinogenic etc.Ĭlass III- laminar flow cabinets are gas-tight, they deliver the highest level of protection achievable to personnel and the external environment.

However, they do not provide cultures protection from contamination.Ĭlass II- are designed for work involving BSL-1, 2, and 3 materials, and they also provide an aseptic environment required for cell culture experiments. What are the classes of laminar flow hoods?Ĭlass I- offer significant levels of protection to laboratory personnel and to the environment when used with correct microbiological techniques. There are three kinds of laminar flow hoods, designated as Class I, II and III, each have been established to meet various research and clinical requirements. Depending on the requirement- the flow can be horizontal, blowing parallel to the work surface, or vertical, blowing from top down onto the work surface. The use of a laminar flow hood is to shield the working environment from airborne contaminants such as dust, by maintaining a constant, unidirectional flow of HEPA-filtered air over the workspace. The cabinets provide an aseptic work area whilst containing infectious splashes or aerosols produced by microbiological procedures. Withnell Sensors are thrilled to partner Angelantoni Life Science (ALS) to provide a wide range of laminar flow hood/ laminar flow cabinet models.
