XRF Sample Cups
Chemplex XRF Sample Cups are injection
molded from a proprietary high-density polyethylene specially formulated for
this application. The material is characterized with:
- Low trace element impurities
(typical Ca, Mg, Ti, Al, P, Zn in ppm).
- Compliance with RoHS
directive.
- Chemical resistance from
contact with incalculable sample material substances.
- Physical resistance to
thermal and irradiation exposure (melting point: 130 °C, softening point: 123
°C).
- Lubricity to facilitate the
smooth and firm attachment of window films.
Chemplex offers a choice of double
open-ended cells which allow attaching the window films in advance and top
sample filling.
For all nominal 32 mm diameter sample
cups which utilize Snap-On Rings alternatively Snap-On Rings with serrated
edges for trimming extraneous window film can be used.

Series
1000
Double open-ended or single open-ended
cells. The window films are fixed with extra wide TrimLess™ Thin-film Sleeves
designed to envelope and secure windows without trimming extraneous window
film.
Single open-ended cells include external
overflow reservoirs and puncturable ThermoPlastic™ seals for pressure
equalization between the sample cup and sample chamber.
|
 |
Series 1300
Double open-ended cells with re-sealable
caps to equalize pressure differentials between the sample cup and sample
chamber. Caps include external overflow reservoirs. The window films are
fixed with Snap-On Rings assuring leak-resistant seals.
|
 |
Series 1400
Single open-ended cells with option to
accept capillary tubes containing standards or micro-samples. Cells include
puncturable ThermoPlastic™ seals for pressure equalization between the sample
cup and sample chamber. The window films are fixed with Snap-On Rings
assuring leak-resistant seals.
Provided collars are optionally used to
prepare micro-samples or evaporated droplet samples (“sandwiching” sample in
between two window films).
|
 |
Series 1500
Double open-ended cells
with option to attach a microporous film to the back
for pressure equalization in applications using inert helium flushes or
vacuum. The window films are fixed with Snap-On Ring assuring leak-resistant
seals.
Alternatively, to a microporous film uniquely
vented caps can be used (see Series 1600).
|
 |
Series 1600
Slit-vented cell caps used in conjunction
with Series 1500 sample cups to maintain equal pressures and avert distension
or convolution of the thin-film window under positive or negative pressure
conditions.
|
 |
Series 1700
Single open-ended
cells for the preparation of micro-samples or
evaporated droplet samples. The provided collars and Snap-On Rings allow “sandwiching” the sample in between
two window films assuring leak-resistant seals. The cells include external
overflow reservoirs and “Snap-Post” ThermoPlastic™ seals for equalizing
pressure differentials within the sample cup and sample. Jiggling the
integrated “Snap-Post”, which is attached to the ThermoPlastic™ seal ruptures
the seal.

 |
Series 1800
Single open-ended
cells for the preparation of micro-samples or
evaporated droplet samples. The provided collars and Snap-On Rings allow “sandwiching” the sample in
between two window films assuring leak-resistant seals. The cells include external
overflow reservoirs and puncturable ThermoPlastic™ seals for equalizing
pressure differentials within the sample cup and sample.
|
 |
Series1850
Single open-ended
cells designed for instruments requiring an overall
height shallower than conventional sample cups and a wide upper section.
Cells include external overflow reservoirs and puncturable ThermoPlastic™
seals for equalizing pressure differentials within the sample cup and sample
chamber. The window films are fixed with Snap-On Ring assuring leak-resistant
seals.
|
 |
Series1900
Double open-ended
cells for the preparation of micro-samples or
evaporated droplet samples for analysis in helium flush or atmospheric
conditions. The provided collars and Snap-On Rings allow “sandwiching” the sample in
between two window films assuring leak-resistant seals.
|
 |
Series1935-OX
Designed specifically as replacement cups
and vented caps for Oxford analyzers requiring the user supplied L240
aluminum sample holders with interior “O” ring seals (Oxford CK-100
Consumables Kit, P/N 54-CK-100).
|
  |
Series2100
Double open-ended cells which integrate
an internal overflow reservoir for collecting thermally sensitive liquid
samples within the sample cup and thus reducing the likelihood of inadvertent
spillage into the sample chamber. The reservoirs also serve as reference
point for filling cups with uniform sample volumes.
The “Snap-On Cap" includes a vent
hole for equalizing pressure differentials within the sample cup and sample.
The window films are fixed with extra wide TrimLess™ Thin-film Sleeves
designed to envelope and secure windows without trimming extraneous window
film.
|
 |
Series3100
Double open-ended uniquely designed cells
for the preparation of powdered, solid or liquid micro-samples (0.2 – 5.5
cc).
The FunnelShape™ cell interior consists
of a larger conically shaped upper portion, which facilitates sample
introduction, and a lower cylindrically shaped spout, which represents the
actual sample chamber.
The “Snap-On Cap" includes a vent
hole for equalizing pressure differentials within the sample cup and sample.
The window films are fixed with a uniquely designed collar.
Cells fit into nominal 32 mm diameter sample
holders.
