Best Carbon Dioxide Gas Meter (for Biological Incubators)
The CO2 meter for biological incubators is a component of the scientific instrument used to grow cell cultures through optimizing environmental conditions for cell growth. This instrument goes by other names as well, including CO2 incubator and CO2 biological incubator. The carbon dioxide meter itself is used to measure the amount of carbon dioxide present in biological incubators. More specifically, it measures the concentration of carbon dioxide gas present within the incubator in %vol and typically is set at 5% CO2. It is commonly used in biological research labs that require the growth of cell cultures and other microorganisms.
Best CO2 Meter for Biological Incubators?
The best Co2 meter for biological incubators is a unit with a CO2 range from 0 to 10%. This range provides the most accurate measurement for most incubators that require CO2 to remain at about 5%.
What is a CO2 Meter for Biological Incubators?
A CO2 meter for biological incubators is a scientific device used to measure the amount of CO2 present in a given environment. In this specific tool’s context, the environment is that of a biological incubator growing microorganisms. In some cases, it is installed within the incubator itself for greater ease of use.
What is Carbon Dioxide Gas?
Carbon dioxide is a compound composed of two parts oxygen and one part carbon. It is an essential compound to the biological function and development of many organisms.

What is the Purpose of a CO2 Incubator?
In incubators, CO2 serves the important purpose of maintaining the pH present in the incubator to allow for optimal cell growth. Combined with proper humidity and temperature, the controlled presence of CO2 in the incubator allows for key, non-contaminated cell growth.
How Do You Measure CO2 Levels in an Incubator?
In an incubator, CO2 levels are measured using a carbon dioxide meter, sometimes referred to as a carbon dioxide analyzer or carbon dioxide monitor. Such meters come in two different forms of gas sensors: a thermal conductivity sensor (T/C) or an infrared (IR) sensor. Thermal conductivity sensors monitor how well heat transfers through a gas while infrared sensors monitor infrared radiation in the given environment.
Why is CO2 Used in Incubators?
CO2 is used in incubators in order to maintain a consistent pH level. This consistent pH then allows for effective cell growth.
Chemically, CO2 helps to maintain a consistent pH level by reacting with water to produce carbonic acid in a chemical reaction. This carbonic acid then reacts with the bicarbonate ions to produce sodium bicarbonate or bicarbonate. It is this product that assists in maintaining the pH.
What is the Difference Between an Incubator and a CO2 Incubator?
A standard incubator in a biological lab is often referred to as a microbiology incubator. It differs from a CO2 incubator in that it focuses on maintaining a consistent temperature for cell growth while CO2 incubators often maintain the temperature in addition to maintaining the pH of the environment and, as a result, the subsequent culture.
Oxygen can be found in a CO2 incubator since many cells require oxygen to survive. This can be a limitation of the devices in some cases, however, in the case of anaerobic bacteria that do not grow in environments where oxygen is present.
CO2 incubators themselves have a wide range of costs. At the low end, some are about $3,000, while at the high end, some are about $20,000. Many factors contribute to this wide range including what features are available and what maintenance the seller is willing to offer.
5% CO2 is used in biological incubators in order to ensure the correct, constant pH is maintained. The CO2 serves to create bicarbonate that acts as a buffer and keeps the pH level maintained. As such, if a researcher wants to maintain a pH level of 7.2-7.4, as is typical for normal tissues since it is near neutral, he or she must calculate the amount of bicarbonate necessary for this pH and adjust the percentage of CO2 accordingly. Most cell cultures will maintain the correct pH when the CO2 meter tracks a CO2 concentration between 4.5% and 6.5%, with 5% being the common measurement used.
CO2 incubators do not have a set temperature. Rather, the user can adjust the temperature to what they deem is best for optimal cell growth. For human iPS cells, this is 37 ºC but the ideal temperature should be adjusted for other cell types if they grow best in different temperatures.
What is the Function of CO2 in a CO2 Incubator?
The general function of CO2 in a CO2 incubator is to provide ideal growing conditions for the cell cultures and microorganisms being grown. More specifically, the CO2 serves to balance the pH levels in the incubator.
How Long Can Cells Survive Outside of an Incubator?
The total length of survival for cells outside of the incubator ultimately depends on the type of cells used—some cells can survive much longer than others outside of the incubator. One of the largest concerns for cell survival outside of the incubator is not actually the presence of CO2, rather it is the temperature of the environment in which the cells reside.
How Accurate are CO2 Meters?
CO2 Meters are accurate but one must check the specifications of the product.
As temperature and humidity increase or decrease, the accuracy will vary. Typical accuracy for CO2 meters is about 5% of the full range. But again, this is worst case scenario when termperature and humidity are approaching the maximum permitted. Typically, however, under normal operating conditions a CO2 for incubators should read within 0.3% of the CO2 real value.
What is the Principle of an Incubator?
The basic principle behind the use of an incubator is that microorganisms, which are the cells that will be grown within the incubator, depend upon specific features within their environment for their growth and reproduction. As such, incubators serve to regulate temperature, oxygen levels, carbon dioxide levels, pH levels, and humidity in order to better allow the cells to develop.
Most mammalian cell culture incubators will have CO2 concentration set to 5%, but researchers should take care to evaluate their own cell’s growth conditions and adjust the CO2 levels accordingly.
What are the Types of Incubators?
- Poultry incubators function to keep eggs from fertilized birds warm until hatching.
- Infant incubators function to keep babies warm when they are unable to properly regulate their own temperature and/or are born prematurely.
- Biological incubators promote the growth of cell cultures and microorganisms by maintaining an optimal environment for the specific microorganism being grown.
Why Do We Place Cells in an Incubator with 5% CO2?
5% CO2 is used in the incubation of cell culture in order to maintain an adequate pH to foster cell growth. In the environment, the CO2 acts as a bicarbonate buffer and also provides some nutrients to the growing cells.
How Does a Laboratory Incubator Work?
By definition, a laboratory incubator is a piece of scientific equipment that is both heated and sealed and used to control an environment conducive to microbiological growth conditions. It does this through monitoring and maintaining temperature, humidity, and gas concentration.
What is a Humid CO2 Incubator?
CO2 incubators are used to maintain a high humidity over time for cell growth that is typically between 95% and 98%.
What is the Importance of an Incubator in a Biological Laboratory?
Incubators are an essential part of biological laboratory equipment that allows for the growth of cell cultures in a constant, set environment conducive to the optimum growth of cells.
What Type of CO2 is Used in Incubators?
In biological incubators, CO2 is set to the desired concentration, often 5%, and tracked using a CO2 meter for biological incubators. This may not be the same for the other types of incubators, poultry and infant.
Is Carbon Dioxide Dangerous?
Exposure to high levels of carbon dioxide can be dangerous. In fact, increasing levels of carbon dioxide is a large concern for climate change. In the biological incubator, however, short exposure should not cause long-lasting damage to users assuming adequate ventilation is present.
- A CO2 meter is a tool used to measure the CO2 concentration within a biological incubator.
- A CO2 meter is also called a carbon dioxide monitor, carbon dioxide analyzer, carbon dioxide detector or CO2 analyzer.
- Maintaining CO2 concentrations allow for the ideal environment for cell growth.
- CO2 meters for biological incubators are used in biological laboratories-- from government laboratories, private laboratories, and to academic laboratories.
