General description

Use the ENVI-Disk Holder with 47 mm ENVI-DSK SPE disks.

The unique design of the holder allows each disk to be installed and held firmly in place without wrinkling and tearing. A screw clamp provides uniform pressure on the disk and the sealing surfaces to prevent troublesome leaks - spring-loaded clamps cannot offer the sealing integrity of the ENVI-Disk Holder.

The unit consists of a 1 L sample funnel, a threaded screw clamp, a PTFE disk support, and a PTFE filter base/adapter with a vacuum attachment fitting. The filter base fits onto any 1 L flask that has a 40/35 tapered ground glass neck. Use 25 x 250 mm test tubes to collect disk eluates.

To use the holder, place the base/adapter on the 1 L flask and center an ENVI-DSK on the disk support in the base. Loosen the screw clamp to install the funnel, then tighten to secure the unit. Attach the base/adapter to a vacuum source, and the unit is ready to use.
