Thomson Transfer Caps
Simple Aseptic Connections
Thomson Transfer Caps when used in conjunction with Optimum Growth® Flasks eliminates the need to move cells to an intermediate vessel for scale up or seed cultures. The ability to pump into the Optimum Growth® Flask makes filling with media from a bulk source a simple aseptic process. Transfer Caps in conjunction with the Thomson Optimum Growth® Flasks can be used for reagent addition, seeding of larger bioreactors or cell bags, pumping of media into flasks from large drums or bags of media and other liquid media transfers into and out of bioreactors.
Transfer Caps are compatible with the following Optimum Growth®Flasks 1.6L, 2.8L and our popular 5L.
