Features And Applications Of Vacuum Filtration System
Vacuum filtration system is a kind of vacuum filtration device, which ingeniously combines all the components needed for Vacuum filtration on one body, saving space and simple operation. It is widely used in laboratories, including various microbial tests in food, medicine, beverage and drinking water industry, determination of suspended solids in the field of environmental protection, sample pretreatment or solvent purification for micro analysis such as HPLC, GC, AA, etc.
The Vacuum filtration system consists of a filter bottle device and a vacuum pump: The filter bottle includes a triangle collecting bottle, a sand core filter head, a filter cup and a fixing clamp.
1. The filter bottle is made of high-strength and extra hard glass material, with resistance to range temperature change up to 270 degrees and good pressure resistance.
2.The filter bottle is produced in batch, which not only has exquisite appearance, uniform wall thickness, but also has good interchangeability.
3.The oil-free vacuum pump designed for the filter bottle device is compact and practical, easy to operate, high efficiency and low noise. We also provide imported original pump for users.
4.The solvent can be directly extracted from the components, which can make the filtration process as fully sealed as possible, reduce pollution and enhance degassing effect.
Product features of Vacuum filtration system:
1.Filter funnel cup cover: standard with filter funnel cover, can help you to do more microbiological tests.
2. Overflow protection device: the receiving bottle is designed with overflow protection device to prevent water from being pumped out of the bottle.
3.Waste liquid extraction and transfer cover: the receiving bottle is designed with waste liquid extraction and transfer cover, which can change the receiving bottle into waste liquid bottle at any time.
4.Membrane gasket diversion design: the membrane gasket Xuanli diversion design can greatly improve the filtration rate, so that you can complete the experiment in less time.
5.The filter bottle group is made of PES advanced engineering plastics: the filter bottle group is injection molded with PES engineering plastics, with strong impact resistance and high temperature resistance (180 ℃), which can be directly used for high temperature and high pressure sterilization.
6.Small volume and safe operation: it is a system integrating filter bottle group and vacuum source, giving full play to industrial design ingenuity. In addition to reducing half of the floor area of the traditional combination, it also uses a fence platform to fix the waste liquid bottle, so as to prevent the operator from accidentally touching the bottle and dumping it.
Use of Vacuum Filtration Hawach vacuum filtration is a standing device for the chemical laboratory. According to the needs of the operator, the filter membrane with different materials and different filtering apertures can be selected, and the effects of removing impurities, purifying and eliminating bacteria in the solvent can be achieved.
In the chromatographic analysis, the solvent which is filtered by the chromatographic column not only can effectively prolong the service life of the chromatographic column, but also obviously improves the data precision of the analysis system due to the vacuum degassing effect of the chromatographic column. The method is mainly applied to high-performance liquid chromatography mobile phase filtration, particle material analysis and microbial contamination detection.
Basic Operation Knowledge of Vacuum Filtration
1. The vacuum filtration is fragile, must not be moved as a whole, and especially cannot be moved with clip.
2. The membrane does not divide anyway, but it is best to smooth and face up, and the effect of downward filtration on the rough side will be good.
3. The filtered solvent should avoid secondary pollution.
