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 |
