SpectroCertified® XRF Sample Cups
Chemplex Industries, Inc. maintains a design engineering department together with a contemporary equipped machine shop facility. Chemplex products are manufactured “in-house” starting from the initial product conception, design, prototype, testing, and evaluation stages to finished inventoried products. In many instances, the machinery to make a product is not available necessitating the “in house” design and custom fabrication of the actual production equipment.
The design of sample cups begins with an innovative idea for a method of containing and handling liquid and powdered sample substances for x-ray analysis. Many Chemplex XRF Sample Cup designs and applications are classified as innovatively unique and have been awarded intellectual property status with the USPTO.
With a battery of injection molding machines and adjunct equipment in its manufacturing section, sample cups are: manufactured on a daily basis; subject to quality control at the production stage; packaged and labeled to avoid contamination; and inventoried under a protective environment to maintain their original quality and to assure prompt delivery.
SpectroCertified® XRF Sample Cup Quality Starts with a Special
Formulated Polyethylene
Chemplex XRF Sample Cups are injection molded from a proprietary high-density polyethylene specially formulated for this application. The material is characterized with:
- Compliance with RoHS Directive
- Absence of “whitening” agents that may potentially influence x-ray data
- Lubricity to facilitate the smooth and firm attachment of thin-film sample support windows
- Physical characteristics for performance and resistance to thermal and irradiation exposure
- Chemical resistance from contact with incalculable sample material substances
- Low trace element impurities
