2. Overview
Nitrogen oven is a standard medium for contamination-free storage. Being
inert, it neither reacts with stored materials nor carries moisture, keeping
the sample safe and contamination free. It features a temperature controller
with PID controlled auto calculation and single segmentation control.
Adjustable air throttle is directly connected to the airexhaust duct. High heat-
resistant door and fiberglass wool insulation provides effective sealing.
