Contained Powder Handling


Discharging Isolators

PSL has a complete range of contained vessel discharging solutions with down to nanograms containment levels.

Our Isolators enable contained sampling and offloading from reactors, filters, filter dryers, dryers, mixers and other small-scale synthesis to full scale production vessels. The level of containment can be selected to suit specific operating procedures.

PSL Heel Recovery System

We provide integration of discharging isolators with a wide range of vessels, and can supply complete process solutions with the integration of PSL’s filter dryers, filters and tray dryers.

PSL has refined its filter dryer discharging isolator to increase yield productivity. PSL's pioneering Heel Removal Glovebox can be mounted on the side of any filter dryer vessel and provides a complete product recovery during the offloading operation with raking tools and a unique discharge plug valve.
