Desktop high-speed centrifugeThe development of centrifuges is an instrument for separating samples, widely used in biomedical, petrochemical, agricultural, food hygiene and other fields. Since its inception, centrifuges have undergone changes in low speed, adjustment, and overspeed, and their progress is mainly reflected in two aspects: centrifugal equipment and centrifugal technology, which complement each other. From the perspective of rotational speed, desktop high-speed centrifuges basically belong to the category of low-speed and high-speed centrifuges. The development of universal desktop centrifuges has blurred the boundaries between low-speed, high-speed, micro and large capacity centrifuges. The numerous rotors provide researchers with a wide range of applications and have become models for scientific research laboratories.
Desktop high-speed centrifugeMaintenance precautions
1. Clean the centrifuge chamber and rotor, and dry the condensed water inside the chamber.
2. After use, open the door until the chamber returns to room temperature.
3. Balance the sample before centrifugation.
After centrifugation, attention should be paid to disinfection and sterilization.
5. Select as needed and increase the sample size according to the requirements.
6. Pre cool the rotor if necessary.
7. Maintain and store the rotating head, paying attention to protecting the counting ring at the bottom.
8. Accurate use of tools and correct installation of rotating heads.
What are the usage guidelines for desktop high-speed centrifuges?
When the centrifuge is in the pre cooling state, the centrifuge cover must be closed. After centrifugation, the rotor should be inverted and placed on the experimental table to dry the remaining water in the chamber. The centrifuge cover should be in the open state.
2. When pre cooling the rotor, the rotor cover can be placed on the platform of the centrifuge or on the experimental bench. Do not leave it on the rotor without tightening it, as if it is accidentally started, the rotor cover will fly out and cause accidents!
3. After tightening the rotary head cover, be sure to touch the gap between the rotary head and the cover with your fingers. If there is a gap, unscrew and tighten it again until it is confirmed that there is no gap before starting the centrifuge.
During the centrifugation process, the operator must not leave the centrifuge chamber. In case of any abnormal situation, the operator cannot turn off the power (POWER) and must press STOP. Before pre cooling, it is necessary to fill out the centrifuge usage record.
5. Do not use counterfeit centrifuge tubes, and do not use centrifuge tubes that are aging, deformed, or have cracks.
6. During holidays and evenings, the centrifuge must undergo a routine safety check before leaving.
7. If there is a machine malfunction or component damage during the use of the instrument, please inform us promptly.
How to skillfully use itDesktop high-speed centrifugeWhat about it? Teach you a few tricks...
At present, electric centrifuges are commonly used in laboratories. Due to their fast rotation speed, safety should be taken into account, especially to prevent the centrifuge from moving while working due to imbalance or aging of the test tube pad during operation, causing it to fall off the experimental bench, or the centrifuge tube to break due to vibration caused by uncovered lid, resulting in glass fragments rotating and flying out, causing accidents. Therefore, when using a centrifuge, the following operations must be noted:
(1) The bottom of the centrifuge casing should be padded with cotton or test tube pads.
(2) If there is noise or body vibration in the electric centrifuge, the power should be cut off immediately and the fault should be eliminated immediately.
(3) The centrifuge tube must be symmetrically placed in the casing to prevent vibration of the machine body. If there is only one sample tube, the other should be replaced with water of equal mass.
(4) When starting the centrifuge, cover the top cover of the centrifuge before slowly starting it.
(5) After the separation is completed, turn off the centrifuge first. After the centrifuge stops rotating, open the centrifuge cover and take out the sample. Do not force it to stop moving with external force.
(6) The centrifugation time is generally 1-2 minutes, during which the experimenter must not leave to do anything else.
Desktop high-speed centrifugePrecautions for use:
1. It is strictly prohibited for any liquids or other debris to enter the centrifuge chamber. Otherwise, it will damage the host.
2. The instrument casing should be properly grounded to prevent accidents caused by moisture damage to the entire machine.
3. Please do not open the upper cover of the centrifuge head at high speed.
When there is an error in the setting, it will automatically sound an alarm to remind you to reset.
