The Specac Apex Quick Release XRF die makes routine pellet preparation simple and faster than ever before. The patented auto-ejector sleeve allows release of the finished pellet without needing to invert, disassemble or, handle the Die at any point during pressing. After compression of the sample, release of the load causes the ejector tabs to swivel over and capture the sleeve in release position. Re-applying a load causes the finished pellet to be pushed clear of the die body.

Process Probes from Hellma Analytics can be used for all kinds of applications. XP probes when accuracy and reproducibility are the main priority HY  Probes  for use in production processes with high hygienic requirements. HD Probes are the best choice for high pressures and temperatures conditions. Contact us for advice on the best configuration for your application.

The Pike Technologies IRIS accessory is the go-to diamond ATR for every lab. It is designed to make IR sampling easy. You can expect high-quality spectra covering a wide range of samples from powders, gels, liquids, solids and more. It is ideal for research, QA/QC and sample identification. Data collection for most samples may be completed in less than one minute.

The MDS-15 from Buck Scientific is a versatile microwave digestion system which can handle both routine work, and  more complicated and demanding samples  with a wide variety of vessels to choose from.  It applies high-energy uniform microwave field for a rapid digestion with a quick 20 minute cool down time.   The quartz digestion vessel enables the whole process to be visible.
