The speed of material filtration is related to the following factors: | |||||
1.Material characteristics (such as: the size of the material and the fluidity of solid-liquid mixing) | |||||
2.The pore size of the filter paper or filter cloth ( the pore size is too small to block the flow rate of the filtrate) | |||||
3.The size of the filter sieve plate. | |||||
4.The vacuum degree of the system. |
1. High quality borosilicate glass 3.3 with excellent physical and chemical properties for glass parts.
2. Perfect sealing property and no dead corner design for charging solution or power more easily.
3. One vacuum value for connecting vacuum pump for processing vacuum filtration.
4. Cost-saving modular design and can be customized by clients' requirements.
5. Safe in operation, easy to move around with lockable casters.
B95 Water Circulating Vacuum Pump

Product Characteristics
1.Obvious water-saving effect. The water added once can be used for a long term.
