Vacuum-Release (VR) Gel-Pak

Semrock utilizes Vacuum-Release^™(VR) Gel-Pak packaging for filters whose part size and narrow substrate thickness make it difficult to remove the filters from standard Gel-Paks. Filters packaged in either 4" x 4" or 6" x 6" VR Gel-Pak require the use of a vacuum release system prior to removing filters using plastic-tipped tweezers. This packaging allows Semrock to keep the parts cleaner, reduce potential defects caused during removal of the filters from the packaging.

Filters packaged in VR Gel-Paks lay on a mesh material over the gel membrane. This packaging provides optimal gel surface contact for shipping and handling of filters, while allowing the gel surface contact to be minimized for filter removal. The basic procedure below details applying a vacuum to the VR Gel-Pak to allow easy removal of the filters.
