Vacuum Filtration Apparatus Operation Process
Vacuum filtration manufactured in Hawach Scientific has better experience in laboratory tests due to the elimination of chemical and mechanical pretreatment, and the ratios of filtration areas are extraordinarily improved. It can ensure accurate and professional test work under realistic conditions with advanced design and superior performance.
Through thousands of tests, Hawach’s vacuum filtration can stand quality tests. Hawach will work with you to select the best system components, accessories, and vacuum filtration steps for your application. Hawach promises to tailor all vacuum filtration apparatus to fit the specific needs of the application.
Vacuum Filtration Steps
Here is the process of vacuum filtration:
1. Connect the flask to an aspirator.
2. Put the funnel on the flask with a filter vacuum to form a seal.
3. Moisten the paper with solvent.
4. Keep the water on.
5. The mixture to be filtered is then decanted into the funnel.
6. Open the clamp on the trap to release the vacuum.
7. Please keep in mind to release the vacuum first and then shut off the water

Vacuum Filtration Apparatus
In order to speed up gravity filtration, we apply a vacuum during the filtration process. A water aspirator is adopted to suck air by fitting on a water faucet and using a fast stream of water through the sidearm of a side-arm (or filter) flask.
Because of the strong suction, a special Funnel (Buchner Funnel) will be used to support the filter paper, or it may break through. Between the flask and the aspirator, there is a safety trap connected to prevent the possible backup of water from the aspirator from contaminating the filtrate. The quick release of the vacuum is due to the clamp on the trap. Tape the flask in case of glass shatters.
Performance of Vacuum Filtration
Hawach vacuum filtration is suitable for chemical analysis, sanitation inspection, environmental testing, and water quality analysis. It is designed to boost productivity and save the organization money by doubling and tripling service life. Cooling and lubricating fluid life can be extended, chip disposal has been streamlined, and the smoothness of the surface is dramatically improved.
Hawach vacuum filtration also pays attention to simplifying operations, reducing machine maintenance, and shortening the tool-changing ratio. All materials used for vacuum filtration are of uniform wall thickness, have an excellent fit with the vacuum pump, and have a good leak-proof ability.
Vacuum Filtration Classification
The vacuum filtration from HAWACH can be divided into a suction filter and a vacuum pump. While the suction filter can be glass with the option of single-channel and multi-collection (1.3.6) or stainless steel with multi-collection (1.3.6). The vacuum pump has two series, Standard Diaphragm Vacuum Pump and Anti-Corrosion Vacuum Pump.
