Multiple-Branch Glass Vacuum Filtration

There are two types of glass vacuum filtration that are particularly popular in the market – single-branch and multiple-branch vacuum filtration. Compared with the single-branch vacuum filtration, the multiple-branch vacuum filtration is more frequently used for laboratory sample filtration with high laboratory productivity.


First of all, the multiple-branch glass vacuum filtration provides a more efficient and faster performance by allowing multiple samples to be filtered simultaneously. Secondly, since it has independent control valves for each filter frame, both single and multiple simultaneous operations are supported at the same time. Thirdly, its unique high-quality glass material could undertake the sterilization under high pressure and temperature. It is typically suitable for laboratory sample filtration, aseptic testing of large infusions, and microbial detection.

Precautions of Operation

During the operation, the sealing of the glass vacuum filtration should be ensured to prevent leakage of solvents or gas. Also, never pump the filtered solution into the vacuum pump while it is connected with the vacuum filtration.

If the filtration speed is slowed down obviously, it is acceptable to pick up the filter screen and rinse the back of it repeatedly by using tap water. After the end of the operation, remember to rinse and completely clean the vacuum filtration.
