SIS GC Cryo-Traps

Adds Cryo-Cooling Capabilities to your GC.
Programmable cryo-cooling and heating trap for the cryo-focusing of volatiles and semi-volatiles at the head of GC capillary columns.

The GC Cryo-Trap is used to cryo-focus volatiles at the front of the GC column in a narrow band for subsequent heating and release. We offer multiple sizes, with both CO2 cooling gas or (for lower molecular weight volatiles) liquid nitrogen.
