2012 CO2 Incubator Survey Results
Cell culture incubators, or carbon dioxide (CO2) incubators, are designed to mimic a cell’s natural environment with a relative humidity around 95 percent and temperature of 37°C.
Cell culture incubators, or carbon dioxide (CO2) incubators, are designed to mimic a cell’s natural environment with a relative humidity around 95 percent and temperature of 37°C. The CO2 concentration, about 5%, is controlled to match physiologic conditions and maintain a constant pH of 7.2 to 7.5.
Top 6 Questions You Should Ask When Buying a CO2 Incubator:
- What measures have been taken in the design to avoid contamination and what feature are included to remove (sterilize versus decon) contamination?
- How does the CO2 sensor contribute to optimal cell growth?
- How does the humidity contribute to optimal cell growth?
- Ask for the uniformity and accuracy data versus asking for a water jacket or air jacket.
- Do you need O2 control to simulate the environment for your experiment accurately?
- Calculate the total cost of ownership on the product over one year including product price, install, regular cleaning labor, material like HEPA filter, etc.
