Vacuum filtration apparatus
The solvent filtration apparatus is widely used in chemistry laboratory. In different conditions, you could use it to filtrate the liquid of HPLC, or to analyze the particulate of particle, or to detect the degree of microbial contaminate and so on.
The solvent filtration apparatus adopts super-quality borosilicate glass, therefore it could filter liquid while analyzing it, as well as sterilizing it in the temperature of 121 centigrade
1. Put the filtering membrane in the middle of the sand core plate
2. Press the filtering membrane by using cylindrical graduated funnel
3. Clamp the flange upper and down edges with the metal clamp
