Dust Generator

acc. to Wright (1950)

The computer-controlled CULTEX® DG – Dust Generator is based on the dust feeder according to Wright (1950) and is recommended as essential peripheral equipment for the exposure of cells to dry powder aerosols.

In combination with the CULTEX® RFS and the CULTEX® Hydraulic Press, the CULTEX® DG completes the optimal setup for in vitro exposure to particles. The included elutriator enables the user to control the size of the delivered particles to under 10 µm.

Especially designed for in vitro exposure systems, the CULTEX® DG is able to provide uniform airborne concentrations of dust for long periods of time.CULTEX® DG
