Selection and operation of handheld centrifuge in PCR laboratory
Palm centrifuges are widely used in life sciences as low-speed and medium-speed microcentrifugation. In routine life science experiments, precipitation or centrifugation of microtubes is an experiment, and a palm centrifuge is an indispensable prerequisite.
The purchase of a handheld centrifuge is actually very simple for people who know and often contact, but compared to those who are new to the centrifuge, the choice of a handheld centrifuge is a very troublesome thing. First of all, in terms of selection, online suppliers are diverse, and their products are all the same, especially in appearance, some are very similar!
At this time, it is necessary to see whether the technical parameters of the centrifuge meet our technical requirements, such as the speed, the mini centrifuge provides you with a single-speed mini centrifuge: 4G/7G/10G/12G, two-speed centrifuge and three-speed centrifuge Speed centrifuge, the other is whether the handheld centrifuge is stable when it is working, whether it has the function of reducing noise, which has a lot to do with the motor of the handheld centrifuge, and now many handheld centrifuges will emit large The sound and the work are extremely unstable, which will lead to customers not having a good experience when using it. The centrifuges provided by Shanghai Maigao Scientific Instruments Co., Ltd. have added noise reduction functions for you to work with ultra-quiet. When the handheld centrifuge is in When working, the noise is very small, the noise at the highest speed is ≤47db. Moreover, it is small in size and light in weight, which is the product characteristic of the mini centrifuge.
In short, the quality of choosing a handheld centrifuge can't just look at the appearance. The motor part is the core of choosing a handheld centrifuge. Don't just look at the cheap price and buy products that have poor performance and are not suitable for you.
After the selection is finished, we will talk about the operation of the handheld centrifuge. The correct operation method of the handheld centrifuge is to reduce the damage of the centrifuge and extend the life of the handheld centrifuge. This can save customers time and reduce economic costs. !
1. The centrifuge should always be in a horizontal position, because the mini centrifuge is small in size and light in weight, and it is easy to shake when it is not working in a horizontal position, which will cause it to not work normally or cause an accident.
2. The voltage of the external power supply system should be matched, and the microcentrifuge should work in an indoor environment, so more attention should be paid to the voltage problem and a good grounding wire is required.
3. Before starting the handheld centrifuge, check whether the rotor is installed firmly and whether there is any foreign matter falling into the cavity.
4. If an abnormal phenomenon is found during the centrifugation process, the power supply should be turned off immediately and reported to the relevant company’s technicians for repair.
5. The sample should be pre-balanced, and the centrifuge cylinder and the sample should be balanced at the same time when using the centrifuge tube for centrifugation. The centrifuge tube of the mini centrifuge is very small, which means that the balance error that the instrument can withstand is also very small, which cannot be compared with the large centrifuge, so the mini centrifuge must be accurately balanced.
6. When volatile or corrosive liquids are centrifuged, centrifuge tubes with a cover should be used, and the liquid should not leak out to avoid corrosion of the machine cavity or cause accidents.
7. After each operation, a record of the usage should be made, and various performances of the machine should be checked and repaired regularly.
