2810 Pellet Press
2810 Pellet Press
The Parr Pellet Press provides a convenient and inexpensive means for compressing powdered samples into pellet form for oxygen bomb calorimetry. Although many materials burn well as a loose powder, others such as benzoic acid must be made into a pellet for safe and complete combustion. Punch and die sets are available in six sizes:

• 1/2 inches • 1/8 inches
• 3/8 inches • 3.0 mm
• 1/4 inches • 4.5 mm

Calorific Standards
Calorific Standards
Parr offers benzoic acid as a secondary standard, traceable to NIST, for standardizing the bomb calorimeters. Also offered is Trizma base (>99.9% by titration) for standardizing the 6755 Solution Calorimeter.
