Products & Reviews

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

3M™ Harvest RC Centrate Chromatographic Clarifier is a single stage single-use chromatographic clarification solution designed to effectively clarify modern cell culture centrates. Centrate clarification using 3M™ Harvest RC Centrate Chromatographic Clarifier may provide many benefits including process compression, high product recovery, and improved process economics.

The 3M™ Harvest RC Chromatographic Clarifier is a single stage single-use chromatographic clarification solution designed as an efficient option for harvesting and clarification of modern cell cultures. Clarification using 3M™ Harvest RC Chromatographic Clarifier may provide many benefits including fewer processing steps, higher yield and lower production time and costs.

Sterivac vacuum-driven filter units are ideal for bottle-top filtering directly into receiver flasks at flow rates as fast as 1.5 L/min. The unique "start & stop" filtration action makes setting up, filtering and transferring the unit to another receiver fast and easy. Push a button to stop filtering, move the device to an empty bottle and restart
