2012 CO2 Incubator Survey Results

By

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:

  1. What measures have been taken in the design to avoid contamination and what feature are included to remove (sterilize versus decon) contamination?
  2. How does the CO2 sensor contribute to optimal cell growth?
  3. How does the humidity contribute to optimal cell growth?
  4. Ask for the uniformity and accuracy data versus asking for a water jacket or air jacket.
  5. Do you need O2 control to simulate the environment for your experiment accurately?
  6. Calculate the total cost of ownership on the product over one year including product price, install, regular cleaning labor, material like HEPA filter, etc.
