GQ75 Tubular centrifuge for bacteria separation

The GQ75 tubular centrifuge is a type of laboratory - scale high - speed centrifuge suitable for separating bacteria!

Working Principle6: The GQ75 tubular centrifuge operates on the principle of centrifugal force. It consists of components such as the machine body, head assembly, liquid - collecting tray assembly, drum assembly, sliding bearing assembly, and motor - drive assembly. During operation, the motor rotates at high speed and transmits power to the pulley and spindle on the machine head through a drive belt and pressure pulley. The spindle then drives the drum to rotate at high speed around its own axis, generating a strong centrifugal force field inside the drum. When the feed liquid is injected into the drum from the bottom inlet, the centrifugal force causes the liquid to stratify. The lighter - weight liquid moves to the center of the drum, flows out from the upper part of the drum, and is collected through the liquid - collecting tray, while the heavier solid substances, such as bacteria, are deposited on the inner wall of the drum and are manually unloaded after the machine stops.

Scope of Application:

The GQ75 tubular centrifuge is widely used in the pharmaceutical, bioproducts, food, and fine - chemical industries. In the pharmaceutical and bioproducts fields, it is mainly used for the separation and purification of antibiotics and yeast, as well as the clarification of biological fermentation broth, which is of great significance for the extraction and purification of bacterial - related products.

Advantages: 

Firstly, it has a high degree of automation, and processes such as feeding, separation, and supernatant discharge during operation are continuously and automatically carried out at high speed. Secondly, it has reliable safety performance, being equipped with protection measures such as torque protection and power control to effectively prevent or reduce damage to the machine caused by sudden faults. In addition, the GQ75 features low noise and good stability, and its operation is carried out under fully enclosed conditions, which can ensure a clean and pollution - free operation site.

However, when using the GQ75 tubular centrifuge for bacterial separation, it should be noted that the actual production capacity varies depending on the characteristics of the material and the separation requirements3. Moreover, the solid content of the suspension should preferably not exceed 3% to avoid overly frequent slag discharge3.
