Use stirred cells for dewatering and concentrating proteins and other biological samples with ultrafiltration membranes. They are also recommended for cellulose membrane filtration of fluids with heavy particle burden. Cells include a preset safety relief valve for pressure buildup, a 1/2" NPT(M) cell cap connection, adapters, and pressure tubing. Top cap can be removed on the 25-, 43-, and 62-mm models to load sample. All cells have polyacetal end caps and stir rod, PTFE stir bar, polypropylene support screen, and silicone O-ring.

The 76-mm model has a 1/2" NPT(M) port for sample loading.
