Introduction to The Three-Branches Vacuum Filtrations System

Hawach Three-Branches Vacuum Filtrations system is an important branch of the vacuum filtration unit. Unlike a typical suction unit, each set can only filter one set of samples. The biggest feature is that at the same time, rely on a set of equipment and a suction pump. Three sets of samples can be filtered.

The triple-type filter product is generally connected to a filter bracket made of metal by a suction pump. Three suction filter funnels can be inserted into the bracket, and a vacuum waste liquid suction bottle is connected between the bracket and the suction pump. The whole system After the vacuum is formed, the atmospheric pressure pushes the filtrate through the filter. For users such as suspended solids detection and microbiological examination, because of the large number of samples that need to be tested every day or once, filtering multiple sets of samples at one time significantly improves work efficiency.

The SLTGF03001 laboratory Three-Branches Vacuum Filtrations system is used as an example to illustrate which components need to be included in a complete system and the functions of each component.

a. Pumping pump: The main function is to realize the negative pressure for the whole system, so as to realize the pressure difference inside and outside the system so that the atmospheric pressure pushes the filtrate through the filter membrane. Equipped with the classic SLVPGM050B Standard Diaphragm Vacuum Pumps, the needle can be used to observe the working condition of the system and adjust the vacuum and filtration speed.

b. Filter bracket: is the most important part of the system, connecting the various components of the system. A suction filter funnel can be inserted into the bracket, which is the center of the complete filtration system.

c. Filtering funnel: Place the filter and hold the liquid sample to be filtered. Equipped with the One-Branch / Three-Branches / Six-Branches filter funnel according to the number of filter holders, it can be autoclaved. The filter bowl and the funnel base are directly connected by a rotary card. They do not need to be sealed by accessories such as clamps or clamps, and can be clamped or loosened by gently rotating.

d. Vacuum pipette: holds the filtrate that has passed through the filter. The material used is conventionally made of plastic or glass. This transparent material allows the user to observe the liquid level and prevent the liquid from being sucked into the pump and damaging the instrument.

e. Water blocking protector: prevent the filtrate from sucking into the protector in the vacuum pump. It is the easiest accessory to be ignored by the user. However, its role is relatively significant, it can be 100% anti-back suction, so that the pump can not be used for years.
