SwitchOver™ CO₂ Cylinder Automatic Backup Switcher

(Click to see larger image)

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.
