 BioDevices' PipetMaster |
Bio Devices Inc. of Allston, Mass., has introduced the PipetMaster™, a one-step, vacuum-driven system for cell culture medium exchange. The PipetMaster permits removal of old media and replacement of new media with the use of one piece of equipment (traditional methods require two). The system reduces the risk of contamination and, according to company literature, reduces the amount of time needed to exchange media by 85 percent. Additionally, the PipetMaster can be used as a liquid dispenser.
