1740 Series 1700 Polyethylene Single Open-Ended XRF Sample Cup with "Snap-Post" Venting, 1.26" Aperture (Pack of 100)

Venting is performed by simply jiggling the "Snap-Post" integrated with the ThermoPlastic seal from side to side. The seal is automatically ruptured permitting a direct passageway from within the sample cup to the sample chamber. Pressure equalization is established that maintains a flat taut sample support window plane. The Integrated External Overflow Reservoir collects thermally sensitive liquids having tendencies to expand. The Collar provided pre-affixes a thin-film substrate to the Cell in preparation for attaching the furnished locking "Snap-On Ring." Alternatively, a pre-attached thin-film may be used to support evaporated droplets or micro powdered samples for thin-layered preparations enveloped in between another thin-film with both secured in place by the attachment of the included "Snap-On Ring." The "Snap-On Ring" and Cell neck utilize the unique Chemplex "bead-to-indent" geometry responsible for firmly securing thin-film sample support window planes to the sample cup Cell. In combination they form wrinkle-free sample planes and leak-resistant seals. Alternately available in nominal 32 mm diameter sample cups with integrated serrated edged Snap-On Rings that allow extraneous thin-film trimming close to the sample cup.
