Biochemical incubator and thermostatic incubator (electrothermal incubator) are two commonly used laboratory instruments. They are both thermostatic incubators. What are the differences between them?
I. Different Product Characteristics
The outer cover of the incubator with electric heating and constant temperature is made of cold-rolled steel sheet stamping die. The surface layer is electrostatic sprayed plastic, the inner liner is SUS stainless steel plate, the two-way sealing property and the insulation material is silicate cotton. The incubator is equipped with a small fan, a light air circulation system, and the temperature in the incubator is uniform. The temperature control equipment adopts a response temperature-controlled liquid crystal display screen without adjusting the temperature control parameters. It has high temperature control precision, no overshoot, timing function and over-temperature protection function. The electrical control part is at the top.
The biochemical incubator is composed of shell, temperature control equipment, heating refrigeration unit and air supply mode channel. The shell personal studio is made of black mirror steel stamping die with arc structure around it. Thick steel plate surface electrostatic spraying is selected for shell case. The tail door is equipped with windows. The height-width ratio of steel mesh in personal studio can be adjusted at will. The polyurethane foam board with good thermal insulation performance is filled between the studio and the box body. Temperature control device mainly consists of temperature controller and temperature sensor. The temperature controller has the functions of over-temperature protection, timing and power-off protection. The heating and refrigeration system consists of heating tube, evaporator, condenser and compressor.
2. Different uses of products
Biochemical incubators are mainly used for ovulation of biochemical reactions, so their key door is made of laminated glass, which can be used for ovulation at special temperatures. Operators can not put forward changes of appearance examination under the premise of destroying the reflection criteria, and can also be used for cultivation of bacterial fungi and control bacteria.
Constant temperature incubator is mainly used for shaping pathogens and manipulating bacteria. As its name suggests, it has good airtightness and stable temperature controllability, but it is not conducive to appearance inspection.
3. Different Temperature Control of Products
There are great differences in temperature range between the two. Biochemical incubator with refrigeration, temperature control is generally 4 - 60 C. Some low temperature biochemical incubators can reach - 20 - 40 C, while constant temperature incubator is usually room temperature + 5 - 60 C. The temperature control accuracy of the biochemical incubator is different from that of the thermostatic incubator. The accuracy of the biochemical incubator is required to be high, about (+0.1 C), while that of the thermostatic incubator is only (+1 C).
Generally speaking, biochemical incubator and thermostatic incubator are all thermostatic incubators, which can be used for shaping tests of microbial and viral infections. Biochemical incubator has refrigeration effect, temperature control category is more common, temperature control precision is higher, and the price is higher. Users can purchase and use it according to their actual needs when choosing.http://www.crxyq.cn/
