The Brief Introduction Components of Vacuum Filtration

General introduction of vacuum filtration device

Laboratory vacuum filtration device is a derivative product developed and improved on the basis of the existing single-layer glass reactor according to the actual needs of customers. It is mainly used for chemical analysis, instrument analysis, sanitary inspection, liquid filtration in the pharmaceutical industry, biological products, pesticides, petroleum, environmental monitoring, etc., to monitor and remove particles and bacteria in the liquid.

The laboratory vacuum filtration device consists of an oil-free diaphragm vacuum pump, an all-glass membrane filter (solvent filter), and a microporous membrane. The all-glass membrane filter includes a filter cup (300mL or 500mL), a triangular liquid collection bottle (1L or 2L), a sand core filter, a fixed aluminum clamp, and a hose.

Vacuum filtration is an instrument used in laboratory vacuum filtration. Generally speaking, filtration can intercept particulate matter, clarify filtrate, sterilize, solid-liquid separation, degassing, defoaming, and other purposes. Drainage bottle, fixed seat, filtration membrane, and water blocking protector of vacuum filtration components. Hawach provided Stainless Steel Single-Branch Vacuum Filtration Manifold and Glass Triple-Branches Lab Vacuum Filtration System for your choice. Here are as follows:

In addition, A relatively complete vacuum suction filter device is composed of many parts. Therefore, the lack of any part will affect the normal use of the instrument. The following is a brief introduction to its components and functions:

Components of vacuum filtration device

1. Vacuum filter pump
The oil-free vacuum filter pump and the oil-free pump is a dry vacuum pumps that can be used directly after connecting to the power supply. The intake end of the filtration filter pump is equipped with a vacuum regulating valve, and the vacuum regulating valve is equipped with a vacuum gauge to facilitate observation of the working status of the instrument and to adjust the pressure and pumping speed as required. Many customers will consult when purchasing a vacuum filtration device that they must purchase a vacuum filtration pump.

Due to the small pore size of the filter membrane, filter paper, filter cloth, or filter screen, there will be a lot of resistance to the liquid passing through the filter membrane. The vacuum filtration pump can form a pressure difference between the inside of the vacuum filtration bottle and the outside so that the outside air can quickly push the filtrate through the filter membrane. Without the use of the vacuum filtration pump, the liquid can only permeate the filter membrane naturally and drip into the collection bottle. Therefore, the suction filter pump is a must.

2. Filter cup
To contain filtered liquid, it is generally more convenient to choose a calibrated cup with a graduation mark as far as possible.

3. Automatic suction cup cover
The user only needs to use a hose to connect one end to the automatic liquid inlet port, and the other end into the filtrate to be filtered. After turning on the switch, the filtrate will automatically be sucked into the filter cup to start filtering, no need to manually pour samples, which is easy to operate.

4. Filter membrane placement base
It is used to prevent the filter membrane. Generally, the surface is required to be flat and will not scratch the filter membrane. The connection with the filter cup is as simple as possible without the use of clamps or clamps.

5. Filtration bottle
It is used to hold the filtrate or waste liquid after the filtration. The bottom of the suction filter bottle of the vacuum filtration device is designed with a quick discharge port. After the filtration, there is no need to remove the suction bottle and pour out the filtrate. You only need to loosen the clamp at the bottom of the liquid distribution port to quickly discharge the liquid, or even change it. Drain the liquid while filtering. It is improving efficiency with easy operation.

6. Fixing a seat
Stabilize the suction filter bottle to avoid misoperation or accidental shaking to make the suction filter bottle fall.

7. Filter membrane

It is equipped with filter membranes with an aperture of 0.45 microns and a diameter of 47 mm. However, users can also choose appropriate filter membranes with aperture and material according to their own needs. The pore size and material are not affected by the filter device and can be selected according to the customer’s experimental needs.

8. Water blocking protector

Built-in PTFE hydrophobic membrane, which can block 100% of the sucked liquid.
