Ready-to-use, sterile Milliflex filter units combine a funnel and a gridded membrane filter in one device. No membrane handling during transfer minimizes the risk of extraneous contamination. Up to twice the surface area of standard 47 mm membranes (depending on filtration system). Milliflex units are disposable and the Milliflex vacuum filtration system can be easily sanitized.
Vacuum manifolds support simultaneous filtration of three or six test samples. Use Millipore glass, plastic or stainless steel filter holders fitted with standard No. 8 perforated stoppers over holder outlets. Manifolds connect to single vacuum source and use separate control valves at each station for independent operation.
