Membrane discs and sheets, filters, holders and cassettes designed specifically for environmental air applications
Product: Air Monitoring Cassettes
Air quality is a concern worldwide due to its known impact on health and environmental issues. Globally, government regulators set standards to control pollution in the air we breathe. Pall began research on the development and production of filters for air sampling and analysis more than 40 years ago. We are now one of the world's largest suppliers of membranes and glass fiber filters designed specifically for environmental monitoring and testing.
As knowledge about the impact of industrial by-products and the need for monitoring have increased, so has Pall’s commitment to supplying products for air analysis. You will find Pall environmental testing products referenced and recommended by regulatory agencies worldwide for air monitoring and hazardous waste analysis of both organic and inorganic matrices.
For the most accurate results in your air analysis, use this guide to select the membrane or filter media optimized for your application. Then choose from our wide selection of complementary products, including filter holders, cassettes, and convenient accessory products.
Conductive, non-static cowl prevents adherence of particles to cassette walls for more accurate analysis. 0.8 µm GN-4 Metricel® (mixed cellulose esters) membrane has a low fiber background count. It is widely accepted for air monitoring of fibers, asbestos fibers, and metals, and complies with NIOSH Methods 7400 and 7402.
Can be used to monitor respirable constituents such as silica, metal, and dusts. Leak proof and tamper resistant. Banded cassettes assure air-tight seal for critical applications. Consistent performance. 100% inspected for complete membrane assembly and secure unit sealing.
GN-4 Metricel membrane assures consistent performance for industrial hygiene sampling designed to meet NIOSH and other regulatory requirements for industrial hygiene sampling using vacuum filtration. Widely accepted for air monitoring of fibers, asbestos fibers, and metals. For open- or closed-face monitoring methods. 0.8 µm GN-4 Metricel membrane has a low fiber background count.
Leak proof cassettes are available in twoor three-piece units.
Stores disc filters and protects filter integrity during microscopic examination. Rectangular base fits most microscope stages. Inner cover ring for air-tight securing of sample does not interfere with viewing. Frosted area on base permits identification of the sample with pencil or marker. Convenient packaging simplifies collecting samples in the field.
Tips have a flat, smooth surface. Polypropylene finger grips provide a comfortable, secure hold. Choose traditional black or ulticolored finger grips. Bright colors make forceps easy to identify, track, and see on the lab bench.
