1. Glass Solvent Filter
Vacuum filtration is used primarily in microbiological and analytical procedures that involve collecting a particulate (bacteria, precipitate, etc.) from a liquid suspension. Liquid poured into a funnel passes through a filter, which retains the particulate, and filtrate can be collected into a filter flask, directly or via a vacuum manifold. This glass solvent filter is made of high-quality extra hard glass. It is sparking and crystal-clear. Its thickness is even, With performance of withstanding voltage and very excellent leak-proof ability. Size agrees with the international standard size. Therefore, it also can be used for sterilization at high temperature and high pressure. All of our glass solvent filters are perfect with our vacuum pumps.
Features
- High quality extra hard glass
- Sparking and crystal-clear, even thickness
- Funnel: 300ml & 500ml
- Flask: 100ml & 2000ml 47mm or 50mm diameter membrane
- Excellent fitting with vacuum pump
- Whole set can be used for Sterilization at high temperature and high pressure.
Applications
- Filtration of aqueous and organic solvents
- Purification and outgas of solutions and HPLC solventsInstruction Drawing:
Caution:
- Keep the liquid under the top If need keep on filtering continuously, please add the liquid after the horizontal line is down to the bottom measure.
- Please don’t collect filtrate to much in the flask. If the horizontal line is near the side arm, the liquid will breathe into the
- If the pump make a halt, when you restart it, please release the air from the vacuum
- When you find the filtration become slower than before, please change the membrane
- Not recommended for use with flammable.
2. Multi-branch Vacuum Filtration Manifold
Multi-branch vacuum filtration system, an integrative filter with reasonable structure and beautiful contour and without wedding spots, equipped with separate valve so that it can filter single sample or multiple samples at the same time so as to save time when testing a lot of samples.Our solvent filtration apparatus made with 316L stainless steel has the characteristics of acid-resistance, alkali resistance, fast filtering speed, long service life, reasonable structure, easily cleaning and operating.
