Cascade Impactor

Biological air sampler, designed to capture viable particles and fractionate sample onto glass or plastic agar plates. Made to the specification of the sampller.

Included are a set of Petri Dishes to give you a running start

The Lab Automate Six Stage Viable Cascade Impactor is a bioaerosol and microbial particle sizing sampler designed to measure the concentration and particle size distribution of aerobic bacteria and fungi in intramural or ambient air for sampling at 28.3 lpm.

It is designed & built to the original An-dersen Cascade Impactor (ACI) speciation, which is known as the world’s reference bioaersol sampler. It is precision-machined out of high-quality aluminum. Each sampling stage has 400 precision machined jet ori??ces with diameters

ranging from 1.81mm on the ??rst stage to 0.25mm on the sixth stage. All collected particles, regardless of size, shape or density are aerodynamically sized.

This impactor works on the principle of inertial separation. When air is drawn through the sam-pler it cascades through the different stages, and the corresponding particulates impact on the agar on the stage and the smaller particulates continue to travel through the stages until they are en-trapped on the corresponding plate or the petri dish containing agar.

These viable bacterial particulates are then incubated and then counted and indented. They can then be recorded and related to where they may be deposited on the human lung.

It allows for size separation from >9µm to <0.3µm. The Six Stage Viable Impactor comprises of an aluminum inlet cone, six jet stages, silicone seals, six glass petri dishes and a base plate that

is held together by three spring action retainer clamps and sealed with high quality silicone O-rings.

The spring action retainer clamps allow for easy disassembly and cleaning.
