Centrifuges are used in the chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipping sectors. Suitable for use in biology, chemistry, genetics, medicine and scientific research.
Problems to be avoided in the use of laboratory centrifuges <br>I don’t know if you have used laboratory centrifuges. When we use laboratory centrifuges, we have to avoid causing unnecessary problems for them. For our use of laboratory centrifuges.
When we put the centrifuge tube of the laboratory centrifuge, we must be symmetrical so that he can run normally and does not generate high vibration. Before the centrifuge is opened, we need to cover the door of the centrifuge. Can't forget it. Regardless of whether the centrifuge is on or off, we must have a certain control on the speed, so that he can slowly add or slow down. Do not adjust too much at all, so as not to affect the machine's use effect and service life.

When the laboratory centrifuge is turned on, we should check his rotation speed to see if it is in the range corresponding to the rotor speed. Of course, let's see if his rotor parts are loose or not. Check whether the connection is normal before the boot. If he has abnormal jitter or sound, then we have to stop immediately for inspection, and we must make a corresponding record. Before the centrifuge is used, we have to adjust the brakes. If the rotor of the centrifuge exceeds the speed when it is rotating, it needs to be shut down. When the rotor is running, we can't disassemble and adjust it.
Centrifuges widely used by laboratory personnel should be familiar with their use
1. The centrifuge should be placed on a level solid floor or platform and strive to keep the machine in a horizontal position to avoid machine vibration during centrifugation.
2. Turn on the power switch, install the required rotor as required, and place the sample with the balance of the tray balance in advance on the rotor sample holder (the centrifuge tube must be balanced with the sample), if there is only one sample tube The branch should be replaced by water of equal mass; the centrifuge tube must be placed symmetrically into the casing to prevent the body from vibrating. Close the cover.
3. Press the function selection button to set the requirements: temperature, speed, time, acceleration and deceleration. The machine with computer control also needs to press the store button to remember the input information.
4. When starting the centrifuge, the top cover of the centrifuge should be covered before it can be started slowly.
5. Press the start button, the refrigerated centrifuge will perform the above parameters to operate, and automatically shut down to the scheduled time.
6. After the centrifuge has completely stopped rotating, open the cover, take out the centrifuge sample, and wipe the rotor and the inner wall of the machine cavity with a soft and clean cloth. After the temperature in the centrifuge chamber is balanced with the room temperature, the cover can be closed.
7. The bottom of the centrifuge casing should be padded with cotton or test tube pads.
8. After the separation is finished, first close the centrifuge. After the centrifuge stops rotating, the centrifuge cover can be opened to take out the sample, and no external force can be used to force it to stop moving;
9. If the electric centrifuge is vibrating or the body is vibrating, the power should be cut off immediately to eliminate the fault immediately;

Centrifuge use precautions:
1. The body should always be in a horizontal position, the voltage of the external power supply system should be matched, and a good grounding wire is required.
2. Before starting the machine, check whether the rotor is installed securely, and if there is any foreign matter falling into the machine cavity.
3. The sample should be pre-equilibrated. When using a centrifuge tube, the centrifuge tube and the sample should be balanced at the same time.
4. When the volatile or corrosive liquid is centrifuged, the centrifuge tube with the cover should be used to ensure that the liquid does not leak, so as not to corrode the machine cavity or cause an accident.
5. Wipe the frozen centrifuge chamber with light action to avoid damage to the temperature sensor inside the chamber.
6. Record the usage status after each operation, and regularly check the performance of the machine.
7. If abnormal phenomena are found during the centrifugation process, the power should be turned off immediately and reported to the relevant technical personnel for inspection.
Pull Stud selects high quality steel, high precision.
Widely used in various three-dimensional engraving milling machine, engraving machine,
Using common rivet rivet is suitable for the inconvenience which riveting (must be from two sides) riveting occasions, so it is widely used in building, automobile, ships, aircraft, machines, electrical appliances, furniture and other products. With open mouth the most widely oval head core-pulling rivet, countersunk head core-pulling rivet riveting occasions suitable for performance needs to be smooth, enclosed core-pulling rivet is suitable for the requirements with high load and has a certain seal performance of riveting.
