![]() Often, laminar hoods will require custom HEPA filters to be created to ensure they create the right pressure drop and fit the equipment perfectly to prevent leaks. Air is taken through this HEPA filtration system and exhausted across the work surface as part of the laminar flow process.īecause a laminar flow cabinet is enclosed on the sides, a constant positive air pressure can be maintained to prevent the intrusion of contaminated room air and personnel contamination. This set up id designed to create a particle-free working environment and provide product protection from contamination. Laminar flow hoods create this unidirectional flow of air with one or more HEPA filters and pre-filters. ![]() Class III biosafety cabinets provide the highest attainable level of protection to personnel and the environment and are suitable for human pathogens and BSL-4 materials. Class II are designed for work involving BSL-1, 2, and 3 materials and provide an aseptic environment for cell culture experiments. Class I is suitable for laboratory personnel with similar air flow characteristics to chemical fume hoods. Each of these are suitable for working with different types of materials as each has its own level of protection and filtration. There are three classes of laminar flow hoods, Class I, II, and III. The flow can either be horizontal or vertical, depending on the lab’s needs. Laminar flow hoods work to protect the working environment from dust and other airborne contaminants by maintaining a consistent, constant, unidirectional flow of filtered air over the work area. They are a key part of any laboratory and a requirement for keeping samples free of contaminants that could damage them. These are hand made in Texas and have a lead time of 17 days.Laminar flow cabinets are used in a variety of environments, particularly where a clean air environment is required for smaller items or samples. You can fit 60+ plates in front of this model if you needed to in 4 stacks of 15. It's the perfect size for 500ml and you can easily pour 20 plates or more per 500ml. We pour out agar with this unit and use a small mason jar to do so. So we recommend it especially for new growers. This is the only way to guarantee the lowest level of contam possible. Optional acrylic shield is also available for those that want to keep things extra clean. But for the most part, this will get rid of your contamination issues. ![]() Certain things you can't control such as a cracked plate, or sneezing directly on top of your agar. I have personally put over 300 plates through this model with almost zero contamination. This unit ships fully assembled, it is plug and play! However we took it a step further and added a small electronics dust filter to the back in order to keep as much dust out as possible, in the first place! This will extend the life of the filter and ensure that your fan works for years.Ĭomes with a removable filter frame so that you can easily access the inside of the unit should you ever need to. These HEPA filters have a built in pre-filter as well as a built in carbon filter. Filters out all contaminates so you can have clean agar, clean grain spawn and grow in peace! These are made with a 17x8 HEPA filter rated at 0.1 microns. A cost effective Laminar Flow hood built by cultivators with cost and ease of use in mind. ![]()
