The desktop low-speed centrifuge, with its five core advantages of low-speed design, precise centrifugal force control, large capacity and flexibility, safety protection mechanism, and intelligent operation, has become the basic equipment in the laboratory for mild separation of cells, proteins, and fragile samples. The specific analysis is as follows:
1、 Low speed and precise centrifugal force control to protect sample activity
The speed range of a desktop low-speed centrifuge is usually 3000-6000rpm, and the centrifugal force (RCF) is controlled at 500-5000 × g. Mild separation is achieved through moderate centrifugal force. For example, in cell experiments, low-speed centrifugation can avoid the shear force generated by high-speed rotation from damaging the cell membrane structure, ensuring the integrity of cell precipitation; In protein separation, gentle centrifugal force can prevent protein denaturation and maintain its biological activity. This "low-speed low centrifugal force" characteristic makes it an ideal choice for handling fragile samples such as red blood cells and lymphocytes.
2、 Large capacity and flexible rotor design, suitable for various experimental needs
The device supports multiple specifications of centrifuge tubes (such as 1.5ml, 15ml, 50ml), and some models can accommodate large capacity samples of 250ml, meeting the requirements of high-throughput experiments. There are various types of rotors, including angular rotors (for rapid particle separation) and horizontal rotors (for clear liquid precipitation stratification), and users can flexibly choose according to the sample type. For example, in blood separation, a horizontal rotor can achieve clear stratification of serum and blood cells; In cell culture medium processing, a large capacity rotor can handle multiple samples at once, improving experimental efficiency.
3、 Security protection and intelligent control ensure the safety and convenience of experiments
The equipment is equipped with safety devices such as door lock protection, overspeed protection, and imbalance detection, which monitor the operating status in real time and automatically stop and alarm in case of abnormalities. For example, when the sample is not placed symmetrically and causes imbalance, the device will immediately stop running to prevent rotor damage or sample leakage. In addition, the intelligent control system supports precise setting of parameters such as speed, time, and RCF value. Some models have memory function, which can store commonly used programs and simplify the operation process.
