Liquid nitrogen cooling stages C1001, C1002, C1003

Simple installation/removal allows use of standard SEM stage
Stages cooled to less than -185 °C by nitrogen gas
Efficient thermal design ensures rapid cool down and stable temperatures
Accurate control through integral heater and temperature sensor
External liquid nitrogen heat exchanger removes vibration due to boiling of LN₂
Higher upper-temperature options for more flexibility in experiments

Liquid helium cooling stage CF302M

Specially designed low drift and vibration, while minimizing liquid helium consumption
CF302M is a helium-cooled stage module that attaches onto the existing stage
Complete system includes flexible transfer tube storage vessel, top fitting with bladder and valve, gas flow controller, gas flow pump, and digital temperature controller

Dual fuel option

Allows liquid helium cold stages to be operated with either helium or nitrogen
Functions by forcing cold nitrogen gas through the circuit similar to the successful C1002 product
