Marple Multi-Stage Impactor
The Marple CEN Series 290X Cascade Impactor has been specified for nebulizer applications. Originally its use was as a personal sampler for industrial hygiene or health & safety applications.
Now as a laboratory device currently validated for use in the Pharmaceutical Industry for establishing accurate aerodynamic particle size distributions from 0.4 to 21 microns, configurable from a 2-stage to an 8-stage impactor, with a flow rate of 2 L/min.
Various model numbers exist due to the ability to reconfigure the stage numbers: 292, 294, 296, 298 shown) Typical applications include Inhalation Toxicology, Pediatric Studies and Characterisation of Nebulized Aerosols
