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.

FAQ's
Q: The regulator appears to be leaking and the area around the nozzle has ice forming. What could be the issue?
A: The cold / frozen area indicates that it the point where a lot of CO2 is escaping. If the output T is frozen, this indicates that there is too much flow through the T. Coming from the bottom of the T is a purge valve. It must be fully closed at all times. Please double-check that no CO2 is coming from the output of the purge valve. If so, turn the silver knob fully clockwise to close it.

SwitchOver™ CO2 Cylinder Automatic Backup Switcher
TREG-SO1:
$535.14
†
- In Stock
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.
The standard model is fully automatic and self-contained. We offer a few add-on options in case you need them. One is an extra switch button for manually switching between sources. This saves time if you have one large CO2 source and a small source that is used only briefly while replacing / refilling the main source. It lets you switch back to the larger source with the push of a button. Another option is an external trigger for facility alarm systems. The standard model beeps and flashes a red light to let you know the active source ran low. The add-on option does these things, plus it closes or opens a relay switch that can be connected to an alarm system to inform staff that monitor building alarm systems. If you need a custom-made internet-based alarm that can send text messages and e-mails, let us know and we can make a version that does that, too!
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.

FAQ's
Q: Can the Switchover be used with input pressures less than the recommended 25 psi (for example 1 bar ~ 14.5 psi)?
A: Yes, your input pressure can be set to 1 bar / 14.5 psi and the Switchover will still work just fine. Our unit uses pressure switches to indicate insufficient tank pressure at about 6 PSI. If the pressure gets down to about 6 PSI, the unit knows that the CO2 tank is empty, which triggers switching to the other tank and sounding of the alarm to remind you to replace the first tank.
