Filtration manifolds 10 x 20 mL or 5 x 100 mL
Handmade filtration manifolds for vacuum filtration of up to 10 or 5 samples on 25 mm filters.
The chimneys made of acid resistant stainless steel hold the filters. Each chimney has a capacity of 20 mL or 100 mL. The chimney base is made of Teflon (PTFE) and stainless steel. By placing the chimneys in a freezer chilled filtration (e.g. TCA) can be carried out. The top and bottom of the manifold and the cylinder collecting filtrates are made of PVC.
A two-way Teflon tap for each chimney permits opening and closing of vacuum for separate samples during filtration. The manifold is supplied with a holder for independent collection of filtrates in 20 mL vials or in 100 mL blue cap bottles. A detachable pipe in the cylinder makes draining of filtrate possible through a pipe stub on the side.
The possibility of independent control of 10 or 5 simultaneous filtrations and the fact that the manifold can rotate makes it well-suited for working with several samples at one time.
