The overflow protector prevents that soil water solution is drawn out of the sampling bottle and into the vacuum unit. As soon as the sampling bottle is full and water enters the protector the protector closes. Thus, this bottle is cut off from the vacuum system while the other bottles still continue to work.

Simply attach the SF-protect to the end of the vacuum tube.

With the overflow protector SF-protect you can also adjust or limit the volume to be sampled. For example, if you want to sample an amount of 100 ml push the vacuum tube deeper into the sampling bottle so the protector is positioned at the height of the bottle's 100 ml line.

The protector opens up again as soon as the sampling bottle is emptied

Typical Applications

• Sampling bottle in vacuum systems

Advantages

• Protects the vacuum pump
• Prevents that samples from different bottles mix
• Allows the pre-selection of the sample volume.
• The sample has contact to Teflon(R) and polypropylene solely and only minimal.
• Any full bottles do not block the complete vacuum circuit.
