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.

The 3 in 1 All-Quartz Flow-Through Cuvette from Hellma offers a threefold advantage, with absorbance, fluorescence, and two optical path lengths in one cuvette. Its innovative design includes precise internal threads for easy and secure tube connection. By turning the cuvette 90°, the second path length becomes available, eliminating the need for time-consuming changes. It  is suitable for high and low temperatures, and is ideal for tablet dissolution analysis and flow-through spectroscopic analysis.

Pike Technologies IRIS

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.
