Bottle Top Vacuum Filtration Cradle Ring for SOLVFil™ Filters, allows for hands-free filtration, provides on/off vacuum flow control manifold, and is for use with both the 500ml and 1000ml SOLVFil™ bottle top filters. Designed to work with a standard laboratory ring stand and "house vacuum" or vacuum pumps.

The unique design of the cradle works as a quick connect to the SOLVFil™ filters which when screwed on to the solvent reservoir bottles, simply sit on the ring and self connect to the vacuum. This connection is simple and fast. The operator can turn on the vacuum once the HPLC solvents have been placed into the SOLVFil™ upper reservoir. When the mobile phase bottles are almost full or enough solvent have been filtered, simply turning off the switch on the Cradle Ring allows for easy disconnect with the filtered and degassed solvents in the mobile phase bottles. 1 EA.
