Comparison of vacuum pump R300 and traditional laboratory vacuum pump
The vacuum suction pump is a vacuum pump that is often used by laboratory users for vacuum filtration with various test vacuum filtration devices. The R300 small oil-free vacuum pumping pump under the St. Stephen's sciencetool brand is designed for laboratory users. It is more in line with laboratory filtration requirements than traditional laboratory oil pumps and water circulation pumps. The main differences are as follows:
1. R300 laboratory vacuum pumping pump adopts oil-free dry design. It does not need to be connected to water source or add pump oil during use. It only needs to be plugged in to use. The water circulation pump needs to be connected to the water source, and the oil pump needs to be added and periodically replaced. This makes the R300 free from the usual maintenance troubles (no need to change the pump oil regularly), and it does not cause the problem of pump oil or water suction.
2. Due to the oil-free design, the oil tank and water tank components are eliminated, which makes the R300 vacuum pumping pump very compact. Its outer dimensions are only 272×121×164mm, and the surface area on either side. Both are smaller than the size of one A4 paper. This saves the bench space of the laboratory and is also convenient for carrying out.
3. Because it is a small oil-free vacuum pump designed for laboratory suction filtration, the vacuum degree and pumping speed are more corrosive to the filtration test requirements than other laboratory vacuum pumps, and the vacuum regulating valve and vacuum gauge are standard. It is convenient for users to observe the degree of vacuum and adjust the pumping speed and vacuum according to specific needs.
4. Compared with the general laboratory vacuum pump, the buffer cup as standard with the suction pump can be used to prevent the filtrate from sucking up and damaging the vacuum pump during vacuum filtration.
