The newly developed CULTEX® DG ? Dust Generator, together with the CULTEX® HyP ? Hydraulic Press, completes the highly integrated setup for the in-vitro exposure of particles together with the CULTEX® RFS. Especially designed for in-vitro exposure systems, the CULTEX® DG is able to provide uniform airborne concentrations of dust for long periods of time.
Features
The CULTEX® DG is completely computer-controlled and allows precise and fully adjustable scraping of the test substance. The rotation speed such as the feed rate of the scraper can be controlled in a wide range by an external computer, connected to the Dust Generators USB socket.
The device is suitable for most dry dusts that can be compressed to dry dust cakes as produced by the CULTEX® HyP.
The dispersion of the particles is carried out at the scraper. An Elutriator, integrated into the CULTEX® DG, retains bigger particles and serves as reservoir for a uniform and ideal particle containing atmosphere, which will be sucked trough the CULTEX® module.
