Polyethylene sample cups offer option to vent cell for pressure equalization purposes.

Cups contain an overflow reservoir for accepting thermally sensitive solution samples that tend to expand during analysis. Simply puncture seal in the centrally located circular depression to release any entrapped gases or vapor pressure build-up during analysis. Consists of a single open-ended cell, a snap-on ring and a collar. Snap-on ring is firmly clamped in position by means of unique tapered “bead-to-indent” geometry matched to the cell neck Collar is optionally used as preliminary holding device for thin-film sample support attachment prior to securing with a snap-on ring. Height: 23mm (0.9").
