I need to identify a gas management system for my bioprocess that can scale from as few as 4 to as many as 6 gases. Here is the further challenge, it needs to be able to direct these gases on demand to headspace or sparge. Any ideas?

Just when you think you’re out, they pull you back in. All kidding aside, it sounds like you should take a look at the Finesse (now Thermo) TruFlow. It is a compact manifold solution designed specifically to address the challenges associated with bioprocess gas management. Per your requirements, it manages up to 6 gases and can direct gases to headspace or sparge. Bonus fact, it was known as the “Zola” during it development. I cannot speak to whether the system is available individually or must be part of a Thermo solution. The link below will provide you with more information.
