Vacuum Pumps used for lab (Scientific laboratories) often have the purpose of being used in the matter of filtration to help separating the substances to be analyzed more conveniently and quickly. In the laboratory, usage of vacuum pump is very common. Vacuum pump with compact size is most suitable because general lab tends to have a lot of equipment and has limited space.
Therefore, GAST DOA Series is perfect choice. It is small but powerful and oil less (oil free). Oil free diaphragm system eliminate chances of oil mist go through lab machine while working and has quiet operation.
How to use the vacuum pump GAST DOA Series in filtration applications.
Filtration with a vacuum pump device is a very popular method because the substance can be filtered quickly resulting in reducing the time in analyzing the substance. By filtering the substance with a vacuum pump, GAST DOA Series is done in conjunction with other equipment including:
The process of filtering substances with a vacuum pump will start from the Buchner cone comes as a filter cone and the filter paper placed to cover all the pores. Filter paper should be wet so that it sits completely against the bottom of the Buchner cone. Then, put on the funnel firmly and hold the stopper on the filter bottle. The sleeve of the filter flask is connected to the GAST DOA Series vacuum pump. After that, vacuum pump operates to create suction power to suck or filter the analyte from the water. The one to be analyzed is the filter.
Meanwhile, the suction speed must also be set appropriately. Otherwise, the sheet used to filter the substance will pass through.
