Improved Vacuum and Bottle Top Filters

Sarstedt proudly announces several improvements to its line of vacuum unit and bottle top filters. All filters now 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 conveniently imprinted onto each filter housing. The redesigned 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.
Sarstedt vacuum and bottle top filters are available in 250 ml and 500 ml volume options, individually wrapped and sterile.
