Larger diameter, square, rectangular, customized geometries and dimensions are encouraged and available upon request

Each pellet die is precision fabricated from high quality hardened 440C stainless steel. The assembly includes a die chamber, one set of anvils(2), a plunger, stepped baseplate and an extraction ring to facilitate sample pellet removal. The overall assembled height including the die chamber, stepped baseplate, two anvils and plunger but without sample powder is 104mm. The die chamber only dimensions are 50mm height x 45mm outside diameter with each anvil measuring 10mm thickness (two anvils are typically used for pellet fabrication although one anvil could be used for thicker pellet fabrication).

REFLEX Analytical recommends the review of the chamber height to confirm there is adequate height to fabricate a pellet to the desired pellet thickness. If required, optional die chamber heights (75mm and 90mm) and plunger lengths can be adjusted accordingly. Offer request for quotation and indicate the required die chamber height. Also ensure there sufficient height between the top and bottom press rams. The pellet dies are commonly used with our series of laboratory presses.

Tungsten carbide anvils are optional and ideal for hard or abrasive powdered sample materials which may tend to mar the surface of stainless steel anvils. Notably, the tungsten carbide transverse rupture strength is 500,000 psi and hardened Stainless Steel is 100,000 psi. Therefore theoretically, tungsten carbide offers 5x the compression strength when compared to hardened stainless steel. A tungsten carbide die chamber and die plunger are also higher cost options.

Other options include a 200°C heating jacket and digital temperature controller; and an optional centered thermocouple port for a customer supplied thermocouple and independent temperature read out.
