LC Switch (3 cylinder version)

Is changing out liquid cylinders to your cryogenic freezers a constant hassle?

Yeah, we know what that’s like.  That’s why we built the LC Switch, an automated switcher for cryogenic liquid cylinders.  It  connects your lab with up to four liquid cylinders, and automatically switches over to a full cylinder when each one empties.

How does it work?

By measuring pressure and temperature, it knows when your cylinder is truly empty so you don’t have to guess.  This switching technology maintains a constant supply of LN2 to your lab so you can focus on what you do best.

Losing sleep wondering if your freezers have enough liquid nitrogen supply?

Worry no more.  The LC Switch hosts a website where you can securely log in from home, office, or smart phone to check the system status.  See which liquid cylinder is feeding the system, which cylinders are empty, and the use-time per cylinder.  Test out our shop demo (username: shop1, password: demo1) or view some screen shots.

Want to be notified when each liquid cylinder empties?  When they all empty?

No problemo.  Receive alerts emailed or texted to your phone whenever a cylinder empties or if they all empty – which hopefully doesn’t happen!  View some screen shots.

Additional features:

  • 2, 3 or 4 cylinder options
  • Audio and visual alarms indicating empty cylinder
  • Automated usage data collection and reporting
  • Easy installation and configuration
  • Stainless steel manifold and enclosure


  • Oxygen sensor/alarm to monitor atmospheric oxygen levels.  Includes horn-strobes.
