These cascade impactors are used for testing aerosol drug delivery devices such as the metered dose inhaler (MDI) and the dry power inhaler (DPI) to determine the aerosol size distribution.
The Model 135 MiniMOUDI is a low-flow rate, low-pressure drop cascade impactor intended for general-purpose aerosol sampling.
The Model 170 Next Generation Pharmaceutical Impactor (NGI) is a high-performance, precision, particle-classifying cascade impactor for testing metered-dose, dry-powder, and similar inhaler devices.
The Marple Series 290 Personal Cascade Impactor is designed to be personally worn by the worker, establishing accurate aerodynamic particle size distributions from 0.52 to 21.3 microns.
The Two Stage Viable Particle Sampler is a multi-orifice cascade impactor that is used whenever a size distribution is not required and only respirable-nonrespirable segregation or total counts are needed.
The Eight Stage Non-Viable Sampler is a multi-stage, multi-orifice cascade impactor designed to measure the aerodynamic size distribution and mass concentration of solid particulates and liquid aerosols directly.
The Six Stage Bioaerosol Sampler is a multi-stage, multi-orifice cascade impactor that measures concentration and particle size distribution of aerosol-type bacteria and fungi in the ambient air.
In the intervening years since BGI created the market for high flow rate 24 hour personal sampling the requirements of the scientific community have matured. BGI’s leadership position in the realm of quiet samplers coupled with strictly limited pulsation has never been challenged. The Omni name refers to the operating system which is also ...
The BioStage single-stage cascade impactor operates on the principle of inertial impaction and meets NIOSH and ACGIH recommendations for sampling indoor and outdoor air for viable microorganisms, including bacteria, and fungi. Made of precision-tooled aluminum, the sampler contains a jet classification stage and base plate precision-threaded ...
BGI has designed the best all around calibrator for verifying and calibrating the properties of Industrial Hygiene Air Sampling Instruments. The Challenger is unsurpassed, when it comes to price and features. The readout is in both Actual flow rate and Standard flow rate. Highly accurate temperature and barometric pressure are also provided. No ...
