Cryogenic Sample Crusher is ...

The JFC series of cryogenic sample crushers consist of a cell, a tungsten carbide steel ball. The sample and the steel ball are placed inside the cell which is attached to a crush rod and the rod is attached to the main unit. The cell is immersed in liquid nitrogen to cool the sample and the steel ball. Then the crush rod is set in up and down reciprocating motion. The steel ball inside the cell pulverizes the sample into a fine powder.

Feature

All kind of polymers, such as plastic and rubber, can be crushed after cooled in liquid nitrogen.

Perfect for sample preparation of polymer additive analysis, outgas analysis from polymers, natural products and biological sample analysis.

Economical operation with low consumption of LN2
The sample cell is made of stainless steel (standard) or titanium (option).
High resolution NMR spectrum can be obtained after pulverization.
When vulcanized rubber is crushed with KBr, IR measurement can easily be made from the KBr disk.
