Description

Technical Field

Its outer shell is made of high-quality cold-rolled steel plates, and the surface uses electrostatic spraying technology. Its working chamber is processed and formed by stainless steel plates or high-quality cold-rolled steel plates and is treated with rust and corrosion prevention. The electrothermal constant temperature incubator for microorganism culture is one type of electrothermal constant temperature incubator.

On the front of the clamping block, there is a fixed connection support plate. Inside the support plate, there is a sliding socket with a limit bar. On the front of the limit bar, there is a fixed connection extraction box. Inside the extraction box, there is a fixed connection spring. By the spring fixed inside the extraction box, when it is necessary to place a culture dish, the culture dish is directly placed between two pressing plates inside the extraction box.
