| Some liquid I was filtering was aspirated into my vacuum line. How do I prevent that from happening? | |
| |
| You should stop filtering before the liquid level reaches the top of the bottle to prevent liquid from entering the vacuum line. To protect you vacuum source from serious damage which can be caused when liquid accidentally enters the vacuum tubing, your setup should consist of both a trap followed by a Millex FG 50 (SLFG05010) hydrophobic vent filter. | |
