Thomson's advancements of unique solutions help scientists achieve higher protein yields in less time. Thomson's Transfer Caps, Sampling Ports, Transfer and Feed Ports, 30mL Optimum Growth® Tube (coming soon), and other products help increase cellular growth efficiency and save time. Thomson takes a systematic approach to cell culture as a whole. The Bidirectional Transfer Cap allows liquid to be pumped both in and out of the Optimum Growth® Flasks to another vessel. The Inversion Transfer Cap enables the sterile transfer of cells to a scale up vessel (Optimum Growth® Flask, cell bag or bioreactor) inside or outside of the hood by allowing precise control of the volume transferred to one or many vessels for inoculation from a single seed culture. Optimum Growth® Tubes represent a quantum leap from spin tubes and other older technology.
