FTIR Pellet Dies | Prepare KBr Pellets

Evacuable Pellet Press Dies for high quality spectroscopy pellets

Specac manufactures a wide range of high-quality Atlas Series Evacuable Pellet Press Dies, suitable for compacting powdered samples into discs or briquettes.

Specac's Evacuable Pellet Dies produce circular pellets in sizes from 5 mm to 40 mm diameter as standard, but other shapes and sizes are available on request. These pellet dies cover a range of load capabilities. These pellet press die sets are particularly well suited for the preparation of solid KBr pellets for FTIR molecular spectroscopic analysis.

Highly polished stainless steel FTIR Pellet Dies

For optimum quality and durability of the pellet die, all parts are manufactured from hardened stainless steel, and surfaces that come in contact with the sample are highly polished. Each Pellet Die comprises an evacuable base, body, plunger, set of pellets, extractor ring, and O Ring Kit.

Difference between FTIR and XRF pellet dies

• FTIR pellet die sets hold samples while they are pressed inside a hydraulic press for spectroscopic analytical sample preparation. They are usually used in conjunction with  potassium bromide powder.
• XRF pellet die sets are generally designed to hold samples inside a hydraulic press for pressing of pellets with a larger surface area/diameter than most FTIR pellets, due to the requirements of XRF. X-ray powder is often used as a binder.

Small 7 mm die for handheld Mini-Press

A 7 mm die is also available for individual purchase. This die is used in conjunction with the Specac Mini-Pellet Press to create 7 mm KBr pellets.
