CO2 Regulator


Precision CO2 Cylinder Pressure Regulator

  TREG-CO2:  $183.78 - In Stock
Image for Precision CO[2] Cylinder Pressure Regulator coming soon!
This precision single-stage pressure regulator performs as well as many two-stage regulators. It attaches to a high-pressure CO2 cylinder, via the standard CGA-320 tank fitting, and maintains a stable lower pressure, set by the user. Nice clear gauges let you monitor remaining pressure in the cylinder and the set/delivered pressure on the low pressure side. TREG-CO2 is ideal for attaching a CO2 cylinder to our DigiTherm® CO2 Incubator.

SwitchOver™ CO2 Cylinder Automatic Backup Switcher

  TREG-SO1:  $513.51 - In Stock
Image for SwitchOver(TM) CO[2] Cylinder Automatic Backup Switcher coming soon!
The SwitchOver™ protects cell cultures, tissue cultures, and embryos in your CO2 incubators by monitoring the pressure in your CO2 cylinder and ensuring that the supply does not run out. Instead, when the active cylinder is nearly empty it will automatically switch your incubator to a new, full backup cylinder. It is simple to use: attach two regulated CO2 cylinders to the two inputs, and your incubator(s) to the output, plug it in, you are all set. Bright LEDs indicate the pressure status of each CO2 tank. When one is nearly empty, the SwitchOver™ switches to the other gas cylinder and beeps to alert you that it's time to change out the empty cylinder. Resetting the system silences the warning. If both tanks are empty, a long continuous alarm is sounded.

Our unique system continues to source CO2 to your incubator even if it loses power, and it remembers which tank it was using last when power becomes available.

It has 1/4-inch (6 mm) OD tube quick connect fittings for its input and output, so it fits perfectly between our CO2 Regulator and our DigiTherm® CO2 Incubator.

Additionally, the SwitchOver™ can be used equally well with inert gasses such as nitrogen, argon, and helium to prevent you from running out of these gasses during the course of your research. This includes Gas chromatography and/or mass spectroscopy (GC/MS) applications, anaerobic incubators, and other applications where the uninterrupted, unmonitored, continuous flow of inert gasses is required.
