2GF two-gas mixer
The 2GF two-gas mixer generates CO2-air mixtures with adjustable CO2 concentration in the range of 0–15%. This mixer is compatible with any microscope stage incubator, and can alternatively be used as a stand-alone device. It is accurate to within ±0.1%, and is supplied with a reusable 0.2-mm-pore polytetrafluoroethylene (PTFE) membrane filtering device.

CV-30 live-cell imaging chamber
The CV-30 live-cell imaging chamber is compatible with any microscope stage capable of accepting a multi-well plate. It features a user-defined bath geometry, bath volume, and a large viewing area. A 0.17-mm-thick glass coverslip forms the top of the chamber and a 1.0-mm-thick round coverslip forms the chamber bottom. The CV-30 is compatible with CytoViva’s high-resolution imaging system, so it can be used for simultaneous observation of fluorescent and non-fluorescent samples.

Oxystreamer O2 and CO2 gas controller
The Oxystreamer O2 and CO2 gas controller has a closed-loop dynamic gas control system and maintains mixed gas concentration to within 0.2% of selected setpoint levels. Ranges covered include O2 concentrations from 0.1% to 99.9%, CO2 concentrations from 0.1% to 20.0% and N2 concentrations from 0% to 100%. The two output streams of this system are suitable for controlling dissolved O2 and CO2 levels in a media or perfusate. The Oxystreamer eliminates the inflexibility and high cost of premixed gas, and inaccuracies due to gas stratification in premixed cylinders.
