Slit-Vented “Snap-On” Sample Cup Caps are unlike traditional caps with vented holes. These innovative caps are specifically designed to form a series of circular physical barriers when attached to a 1500 Series XRF Sample Cup. The barriers are created by the inter-relationship between integrated ridges on the interior of the cap and the Cell Neck when assembled. This forms circular troughs representing passageways leading from the interior of the sample cup to the sample chamber. The barriers present complicated paths of travel for sample particles to reach the sample chamber. Slit-Venting is used instead of traditional holes in order to increase the volumetric quantity of air withdrawal with minimum disturbances to the powdered sample substance while maintaining taut thin-film sample window planes.
The Slit Vented “Snap-On” Caps are affixed to the upper open end of the Cell containing a ridge and after the thin-film window has been attached and the sample introduced. The Caps are designed with the same Chemplex® developed “bead-to-indent” geometry of the “Snap-On Rings” for affixing thin-film window sample planes.
The “Snap-On Rings” supplied with the 1500 Series sample cups are also designed with the same “bead-to-indent” geometry used for safely securing a sample with a taut thin-film sample support window plane.
*Please see the "Additional Info" tab for analyzer equipment compatibility details.
The interior ridges form circular baffles when assembled to a 1500 Series sample cup. The baffles present physical barriers designed to retard or eliminate sample particle disruption.
