Polyethylene, single open-ended cells feature a snap post for venting and an overflow reservoir, making them ideal for samples that expand during analysis.

Simply apply pressure to the snap-post to rupture a thin thermoplastic seal and establish a passageway. Consists of a single open-ended cell, snap-on ring and collar. Snap-on ring incorporates a taper and “bead-to-indent” geometry for establishing and maintaining a taut thin-film sample support plane. Collar functions as preliminary holding device for thin-film sample support attachment prior to securing with a snap-on ring.
