How to Choose a Laboratory Carbon Dioxide Incubator
The carbon dioxide incubator is suitable for cell or tissue culture, and microbial research, and is the key equipment for life science research. Co2 incubators are widely used in the research and production fields of microorganisms, agricultural sciences, and medicines. As an important instrument for cell culture, in the process of in-vitro experiments, the carbon dioxide incubator can maintain a stable temperature (37°C), CO2 concentration (5%) and high relative saturation humidity (90%), and simulate the growth environment of cells or tissues in organisms, to improve the success rate and efficiency of biological cell or tissue culture. Faced with many carbon dioxide incubators on the market, how to choose it?
The CO2 incubator mainly controls 3 basic variables related to the simulated living environment, namely stable CO2 level, temperature and relative humidity. In order to create a stable culturing environment, these three influencing factors must be considered. When purchasing a CO2 incubator, we should have a certain understanding of these "top priorities" in order to choose a suitable instrument.
I. Temperature control:
Keeping a constant temperature in the incubator is an important factor in maintaining the healthy growth of cells. When purchasing a carbon dioxide incubator, there are two types of heating structures to choose from. One is air jacket heating, and the other is water jacket heating. Although these two heating systems are accurate and reliable, they both have their own advantages and disadvantages.
II. Carbon dioxide control:
CO2 concentration detection can be measured by two control systems, infrared sensor (IR) or thermal conductivity sensor (TC). When the door of the carbon dioxide incubator is opened, CO2 leaks out of the box. At this time, the sensor will detect the decrease in CO2 concentration and make a timely response to re-inject CO2 to restore it to the original preset level.
III. Relative humidity control:
The control of the relative humidity in the incubator is very important. It is necessary to maintain a sufficient humidity level to ensure that the culture will not fail due to excessive drying. Large-scale carbon dioxide incubators use steam generators or sprayers to control the relative humidity level, while most small and medium-sized incubators generate moisture through the evaporation of humidity control panels, and the level can reach 95-98%).
IV. Micro-processing control system:
Every user hopes that the instrument can be convenient and easy to use. The use of micro-processing control system and other various functional accessories such as high temperature automatic adjustment, alarm device, CO2 alarm device, password protection setting, and automatic calibration system, etc. can make the operation and control of the carbon dioxide incubator very simple.
V. Other factors:
Other factors include the control of pollutants, laboratory requirements, temperature control range, incubator volume, special features, etc. These factors should all be considered when purchasing a carbon dioxide incubator.
