LN2-SYS Liquid Nitrogen Cooling Systems
Instec’s LN2-SYS liquid nitrogen cooling systems provide fast and accurate cooling for Instec stages, chucks, and plates. Each system consists of a liquid nitrogen pump, a Dewar, and the necessary tubing. Dewar lids have a stoppered port so that LN2 can be refilled without stopping cooling. The pump generates suction, pulling liquid nitrogen from the Dewar and through the hot and cold stage, chuck, or plate. The pump is PID controlled by an Instec temperature controller with 0.1% resolution. This means when the stage, chuck, or plate is heating, the pump is off; when the pump is on, heating is off. The liquid nitrogen cooling systems are available with multiple pump options and either a 2, 10, or 30 liter Dewar.
