Each stage has 400 precision machined jet orifices. The Six Stage Impactor has a corrosion resistant body and operates at a flow rate of exactly 28.3 lpm (1 CFM). The Six Stage Sampler ensures ease of operation: calibration, sterilisation, and setup and is inspected by our own Impactor Vision Inspection System (IVIS).
Andersen cascade impactor using inertial filter technology (ANIF). The sampler consists of an 8-stage impactor from the Andersen cascade impactor (Tokyo dyrec AN-200), and a nozzle section that will smoothly correct the flow from the final impactor stage with a 0.43 μm cutoff size and then introduce the flow to the inertial filter stage.
Ambient Viable Andersen Cascade Impactors Tisch Environmental ambient viable andersen cascade impactors are used for the collection of airborne aerosols containing bacteria or fungi. These devices come in six stage (TE-10-800), two stage (TE-10-860), or single stage (TE-10-890) variations with an available pump for sampling at 28.3lpm.

Slit impactors have a rotating support stage for agar plates to allow for measurement of concentration over time. Andersen Air Sampler (sieve impactor); TDL, Cassella MK 2 (slit impactors) Sedimentation
In a typical impactor sampler air is drawn into a sampling head by a pump or fan and accelerated, usually through a perforated plate (sieve samplers), or through a narrow slit (slit samplers). This produces laminar air flow onto the collection surface, often a standard agar plate or contact plate filled with a suitable agar medium.

The sampler consists of an 8-stage impactor from the Andersen cascade impactor (Tokyo dyrec AN-200), and a nozzle section that will smoothly correct the flow from the final impactor stage with a 0.43 μm cutoff size and then introduce the flow to the inertial filter stage.
the Andersen viable aerosol impactor (2, 8, 13) sampler or the AGI-30all glass impinger (9), orboth. Analternative to these samplers is the May three-stage glass impinger (10) whichhas somesignificant advantages despite its infrequent references in the literature. This paper presents a compari-son of the May sampler versus the most widely accepted
The Andersen cascade impactor is designed to work “online,” incorporating a nozzle for isokinetic sampling from a gas stream. A precyclone removes particles >15 μm and a filter catches those <0.4 μm. The Sierra, designed for room or atmospheric air measurement, covers a range 0.05 μm to 10 μm. The collected particles are removed and
Aerodynamic Particle Size Distribution (APSD) The Aerodynamic Particle Size Distribution (ASPD), along with Delivered dose, is widely recognised as a Critical Quality Attribute in the in
We compared the yields of 4 recently developed sieve impactor air samplers that meet international standard ISO 14698-1, using 2 growth media (tryptic soy agar and malt extract agar) in real
Particle Impactor Sampling Guide This method of air sampling involves drawing a measured volume of air over culture media in petri dishes. The petri dishes are incubated in the laboratory so the organisms impacted on the plate can grow. The fungi or bacteria are counted and identified. This method commonly uses the Andersen N-6 Impactor TM

Remove the plate from the impactor stage. Replace the plate cover. Label the plate with identification number. Place in a ziplock bag. Clean the impactor stage with an alcohol wipe before next sample collection and when all sampler collections are complete. Plates should be shipped overnight in a cooler with cold packs as soon as possible.
