First, understand the needs of the glove box First of all, it is necessary to clarify the purpose of the use of the glove box and working conditions. Is it used for general experimental operations, or special requirements involving high purity and high vacuum?
Different application scenarios have different vacuum requirements in the glove box. If semiconductor materials are processed, an extremely high vacuum is usually required to avoid the mixing of impurities; while for general chemical experiments, a relatively low vacuum may be sufficient. Second, consider the type of vacuum pump common types of vacuum pumps are rotary vane vacuum pumps, scroll vacuum pumps and molecular pumps. Rotary vane vacuum pumps are simple in structure and relatively inexpensive, but vacuum may be limited. Scroll vacuum pumps have high pumping speed and good stability. Molecular pumps, on the other hand, can realize ultra-high vacuum, but the price is higher and the maintenance cost is also larger. Third, focus on the pumping speed of the vacuum pump
The pumping speed directly affects the time it takes for the glove box to reach the required vacuum level. If the pumping speed is too slow, it may lead to low experimental efficiency. Generally speaking, the larger the volume of the glove box, the higher the required pumping speed. Fourth, the ability to maintain the vacuum degree In addition to reaching the specified vacuum degree, it is also important whether the vacuum pump can maintain this vacuum degree stably for a long time.
A good quality vacuum pump should operate for a long period of time and the change in vacuum level should be within an acceptable range. V. Noise and vibration levels For laboratory environments, vacuum pumps with low noise and vibration levels provide more comfortable working conditions. VI. Ease of maintenance and servicing Choosing a vacuum pump that is easy to maintain and service can reduce the cost of use and downtime.
Some vacuum pumps have easily replaceable filter elements and components that are easy to disassemble and clean. Seven, brand and after-sales service well-known brands are usually more guaranteed in terms of quality and performance, while good after-sales service can solve problems in time when the equipment appears. In short, the choice of vacuum pump for glove box needs to consider a variety of factors. Only according to the actual needs, carefully evaluate the indicators, in order to select the most suitable vacuum pump, to ensure the efficient and stable operation of the glove box.
