Product name: Carbon dioxide incubator
The CO2 incubator mainly consists of box structural parts, temperature control system and CO2 concentration The control system consists of three parts.
1. The box structure is composed of outer shell, insulation material and stainless steel water jacket. The design of the studio is key. The water jacket method is adopted, that is, except for the front glass door, the other five sides are stainless steel interlayers filled with water. Through the circulation of hot water, the studio is surrounded by an interlayer of isothermal water, so the heating is uniform and constant, the temperature rises quickly, and the temperature drops Slow, even if there is a power outage for 5 to 6 hours, the cells can still survive. It adopts a double-layer door design. The inner glass door is convenient for observing cell growth and has less interference with the environment. The inner side of the outer door is equipped with an automatic temperature-controlled lining to prevent condensation and is not affected by changes in ambient temperature. Fans in the studio circulate the gas to make the temperature and CO2 concentration in the studio uniform. The top layer of the water jacket adopts a stepped design (the design has obtained a national patent), which not only ensures a uniform water layer on the top of the incubator, but also avoids the impact of the high temperature of the fan motor and environmental changes on the temperature uniformity of the studio. The manufacturing process also ensures that body deformation is reduced.
2. The temperature control system adopts a three-way detection and three-level control circuit, and also has a circuit to prevent excessive temperature. (Some imported incubators have single-channel detection and secondary control circuits.) The temperature sensor is an advanced voltage-type integrated circuit temperature sensor, rather than the commonly used thermoelectric cathode, semiconductor, thermocouple and other sensors.
3. The CO2 concentration control uses ultrasonic sensors, which have the advantages of stable performance, fast detection speed, adaptability to humid box environments, long life, not easily damaged, and good linearity (this technology has obtained a national patent). Most similar products at home and abroad use thermal conductivity and infrared types. Thermal conductivity sensor structure The thermal conductivity sensor has a simple structure and low cost, but it is too sensitive, is greatly affected by the environment, and is prone to zero drift. Infrared sensors cannot work in humid incubators, so an external sensor is used to pump out the gas in the incubator and condense and dehumidify it before detecting it, and then return the gas back to the incubator. This method has complex pipelines, large mechanical losses, delayed detection results, and a high failure rate.
Automatically control CO2 concentration
As long as a set value is given, the instrument will automatically control the CO2 concentration. Compared with the flow meter method, the operation is simpler, the gas saving is high, the accuracy is good, and the stability is good. .
◆Using patented technology water jacket structure
Using patented technology water jacket structure, the culture chamber can be contained by the water interlayer to the maximum extent, increasing the water jacket capacity, and helping to achieve extremely high Reliability and stability; seamless welding technology makes it difficult for bacteria to grow.
◆Precise temperature control
Using three-way integrated temperature sensors to precisely control water temperature, door temperature, and room temperature, the incubator temperature is rarely affected by changes in ambient temperature; over-temperature dual Layer protection, extremely high security.
◆ Use patented ultrasonic technology to measure CO2 concentration
Using ultrasonic sensors, no mechanical wear, long service life, good stability, and will not be affected by high humidity.
◆One machine for two uses
The temperature and CO2 concentration are controlled separately, and the CO2 control system is turned off, and it can be used as a high-precision incubator alone.
◆Easy to operate, intuitive display
Digital display of temperature, CO2 concentration, door heating, water heating, and water level changes all have LED displays.
◆Double glass door
The 200-liter large box adopts an upper and lower double glass door design, which can greatly reduce the impact of opening the door on the culture room and facilitate quick restoration of the culture environment.
◆Miniaturization
The 50-liter small box can be used as a desktop incubator; because of its small size, the temperature and CO2 concentration recover quickly, and it is particularly gas-saving.
CARBON BIOXIDE INCUBATOR
Carbon dioxide incubator is composed by box configuration, temperature control system and CO2 thickness control system.
◆ Box configuration is composed by crust, heat preservation material , stainless steel water jacket . The design of the workroom is linchpin . It is adopted the water jacket technology , namely , except the front glass door , other 5 surfaces are all stainless steel interlayer full with water . With hot water circulation , water interlayer in same temperature surrounds the workroom. Heated equably, temperature invariableness, the fast rising temperature and the slow falling temperature are the advantages of this workroom. Though power cut for 5-6 hours, it can also make the cell alive. Adopt the design of double door , the glass door inside is convenient for observation of dew and other influence . The air in the workroom can be circulated by fans for uniformity of the temperature and CO2 thickness in workroom . The top of the water jacket is step shape ( declared the nationality patent), for uniformity of the mater tier in incubator and prevention of high temperature in workroom. The manufacturing technical can also guarantee the shape of the incubator.
◆The circuit of 3-route check, 3-step control and high temperature prevention is adopted in temperature control system. (some import incubator circuits are single route check,2 step control) Temperature sensor is unusually adopted the voltage
concentration circuit .
◆CO2 thickness control is adopted the ultrasonic sensor with stable capability , fast checking speed for adaptation of the wet environment , long service life and good linearity . (Declared the nationality patent) . But the same kind of this products in the world are adopted the heat conduction and infrared . The sensor configuration of the heat conduction is simpleness and low expedition , but it is sensitive by environment influence and easy to zero drift . The infrared sensor can't work in wet incubator, so it is adopted with the outlay sensor by pump the air inside and check after freezing, and then it will send the air back to the incubator. This system has disadvantages of complex duct, high mechanical waste, hysteresis checking result and high fault rate .
Auto-control of CO2 thickness and comparison of flow are worked when a value is set , so it has the advantages of easy operation , high gas save , high precision and good stabilization .
