What are the Correct Membranes for Your Filtration Needs?

Steripak-GP filter units are designed for larger scale pressure-driven filtration of tissue culture media with or without serum. They are single use and are not autoclavable. The filter units come in two sizes, with the smaller unit able to filter up to 10 L and the larger up to 20 L. Both sizes utilize the low protein binding, fast flow 0.22 µm EMD Millipore Express membrane.

Steritop bottle top filter units provide a large filter area for rapid sterile filtration of aqueous fluids into narrow-mouth (33 mm) or wide-mouth (45 mm) bottles. A small tab inside the funnel secures an optional prefilter in-place during filtration. For added protection against contamination, the threads for bottle attachment have been slightly recessed in case the funnel accidentally touches a work surface
