Installation and Operation
Installation
- Assemble the VFC 47 Continuous Filter Holder as shown below.
- The GL45 filtration adapter and bottle are not included with the purchase of a VFC 47.
Operation
- Turn on the pump, block the inlet (3b), and regulate the desired vacuum by vacuum regulator (6b).
- A trap bottle is recommended to connect before the pump when handling moisture-rich samples.
- Screw the GL45 filtration adaptor onto a laboratory glass bottle, and insert the filter holder on it using a silicone stopper (4a).
- Place a membrane on the support base (3a), assemble the cover (1a) onto the support base, and clamp them securely.
- Connect the GL45 filtration adaptor to the pump inlet (3b) using a silicone tube.
- If the silicone tube is incompatible with the medium, replace it with a suitable material, such as PTFE.
- Connect the filter holder’s inlet hose barb to the sinker using tubing, then place the sinker (6a) into the sample container for continuous filtration.
- Power on the pump to start filtration.
Maintenance
- The vacuum pump is not autoclavable. Please clean the surface with pure water or 75% ethanol.
- After finishing the experiment, please remove the liquid in the moisture trap and keep pumping the air for at least 2 minutes to withdraw the residual steam.
- Please remove the liquid in the moisture trap after every use. If the liquid in the moisture trap is more than 70%, please stop the experiment immediately to empty the liquid.
- Filtration apparatus and accessories are autoclavable (121°C, 1 bar, 20 min). Please make sure to rinse the apparatus with pure water and separate each part before autoclaving.
- Valve plate(s), O-ring(s), silicone tube(s), and diaphragm are consumables, it is recommended to replace them every year or as needed to ensure good operation.
How to clean the VFC 47 Continuous Filter Holder
- Disassemble the filter holder and vacuum bottle completely.
- Soak all parts in clean water. Avoid abrasive cleansers. If necessary, use a soft bristle brush or sponge to remove residues.
- Rinse all parts thoroughly. The final rinse should be done with distilled or deionized water.
- Store in a clean, dry place.
