Slit-Vented Sample Cup Caps are used in conjunction with Series 1500 Sample Cups for differential pressure equalization. The interior of the slit-vented Caps integrate a series of concentric ridges that form physical barriers when attached to the Cell Necks of 1500 Series Sample Cups. The space in between the barriers serves to provide a tortuous passageway from within the sample cup and sample chamber to maintain equal pressures and avert distension or convolution of the thin-film sample support window under positive or negative pressure conditions. Available in nominal 32 and 40 mm diameters.

SERIES 1700: Single Open-Ended Sample Cups, Snap-Post Venting and External Overflow Reservoirs

Gateway to XRF Sample Cup Work Stations

Chemplex XRF Sample Cup Work Stations represent a novel design approach in providing an organized resting place for sample cups after affixing thin-film sample support windows, preventing contamination to thin-films by eliminating contact with a counter top surface and facilitating the sample filling procedure.

A work station consists of single or six individual conical shaped cavities that allow acceptance of any size sample cups of the same or dissimilar diameters ranging from 24 mm to 45 mm. The conical shape of the cavity allows the smaller diameter sample cups to rest lower into the cavity than the larger sample cup diameters while maintaining the sample cups level in position. Multiple cavity work stations allow for the advanced preparation of a large number of samples in readiness for transporting to the instrumentation for x-ray analysis and a means of storage for future referral.

Work stations are offered in two models: a handy circular one position work station and a rectangular six position work station. For convenience, the cavities in the six position work station models are sequentially numbered. Work stations are fabricated from black anodized aluminum with white numbers stamped adjacent to the positions in the multi cavity work station.

Gateway to XRF Sample Cup Transfer Pipettes

Disposable clear polyethylene pipettes simplify and facilitate transferring fluid and viscous petroleum samples into single or double open-ended sample cups and for general laboratory uses. Ensure similar sample volumes for x-ray analysis, eliminate spillage and prevent contamination possibilities. Easy-to-read chart relates correct pipette to XRF sample cups; affordably priced for disposability.

Gateway to Palm-Held Snap-On Ring, Sleeve and Thin-Film Fastener

This handy device is small enough to fit into a palm hand and takes the soreness out when assembling XRF sample cups with Snap-On Rings or Sleeves.

Simply align the Palm-Held Fastener over the Snap-On Ring or Sleeve and gently push down. During this process, the thin-film sample support window remains stretched over the sample cup Cell and upon assembly completion it’s firmly secured for a taut thin-film sample plane.

Gateway to Snap-On Ring and Thin-Film Fastener

XRF Sample Cups designed with a “Bead-to-Indent” geometry for affixing thin-film windows to the Cells with Snap-On Rings are greatly facilitated by using the Snap-On Ring Fastener. By applying a slight amount of pressure to the finger lever the Snap-On Ring is slowly and uniformly attached to the Cell. During the process assembly process the thin-film substance maintains its tautness to form a perfect sample cup presentation effortlessly.

Gateway to Palm Held Vent-Hole Punch

XRF Sample Cups requiring venting for differential pressure equalization, the Vent-Hole Punch is an invaluable palm held tool.

Through a series of counter-bores, the Vent-Hole Punch will accommodate the majority of sample cups integrating a ThermoPlastic™ Seal.

Simply fit the Vent-Hole Punch over the closed end of the assembled sample cup and push downward. This action extends an awl that punches a hole through the ThermoPlastic™ Seal without any effort. The awl retracts after use in readiness for the next preparation.

Gateway to Microporous Polypropylene Gas Permeable Film Membrane

Microporous Gas Permeable Film is used in applications that require differential pressure equalization between the sample chamber and within the sample cup containing a non-volatile liquid or powdered sample material. The micro pores follow a tortuous path of travel from one surface of the film to the other. Powdered sample particles are too large to become withdrawn and liquids similarly behave. The thin-film sample plane remains taut.
