Vacuum And Bottle-Top Filters

Vacuum unit and bottle top filters contain a low binding, fast throughput PES membrane with a pore size of either 0.22 μm or 0.45 μm. Lot number, membrane material, and pore size are imprinted onto each filter housing. Ported neck is compatible with 45 mm receiving bottles and is securely attached to the filter housing for an improved connection. Vacuum units are assembled with new ergonomic receiving bottles that feature a wide base for stability and two opposing indented sections for improved grip and handling.

All items are individually wrapped, sterile, and certified non-pyrogenic and non-cytotoxic.
