1. what is an incubator?

Incubator refers to a temperature-controllable box device mainly used for cultivating microorganisms, plants and animal cells. Some have a two-way temperature adjustment system with refrigeration and heating. It is the basic scientific research department of biology, agriculture, medicine, environmental protection, etc. Experimental equipment is widely used in constant temperature culture, constant temperature reaction and other tests.

The main characteristics of the incubator are: the box adopts polyurethane and other foam as the heat insulation material, which has good isolation ability from external cold and heat; the inner cavity is mostly made of stainless steel, which has strong corrosion resistance; it has heating, Refrigeration and automatic temperature control device.Can sensitively adjust the temperature inside the box.

2. incubator need to monitor what?

Incubators are now used in many laboratories to simulate the formation of a cell/tissue-like growth environment in an organism, such as a stable temperature, a stable carbon dioxide level, a constant pH, and a relatively high relative humidity.

In the process of using the incubator, the content of oxygen and carbon dioxide in the incubator should be strictly monitored. Therefore, a large number of sensor detection elements are usually provided in the inner chamber of the carbon dioxide incubator. For example, a temperature sensor, a carbon dioxide sensor, an oxygen sensor, etc. A combination of sensors and a microprocessor are placed in the gas flow path to provide timely monitoring of temperature, CO2 and oxygen concentrations in the gas flow path for the most accurate control of the elements of the incubator environment.

Why should 3. monitor carbon dioxide?

Generally speaking, the pH value of the cell culture medium is between 7.0 and 7.4. Since the carbonate pH buffer system is a physiological pH buffer system, most culture solutions use it to maintain a stable pH value. When preparing the culture solution with powder, it is often necessary to add a certain amount of carbonate. For most of the culture solution with carbonate as pH buffer system, in order to keep the pH stable, the carbon dioxide in the incubator needs to be maintained between 2-10% to maintain the dissolved carbon dioxide concentration in the culture solution.

Here, I would like to recommend you a COZIR-W of sensors for detecting CO2. This sensor is an infrared spectrum sensor specially developed by GSS in the UK for detecting CO2.

Overview of 1. COZIR-W

COZIR is a CO2 sensor with ultra-low power consumption (3.5mW) and high performance, which is ideal for battery-powered products and portable devices; based on IR LED technology and innovative optical path design, COZIR is the lowest power NDIR sensor; and optional temperature and humidity output. COZIR is the third generation product of GSS company and is the leader of IR LEDCO2 sensing technology. The ranges are 0-5%,0-20%,0-60% and 0-100% respectively, which makes the COZIR-W suitable for applications like diving, industrial safety and automotive manufacturing industries.
