Nitrogen oven LB-21NTO

Nitrogen oven LB-21NTO

Nitrogen oven LB-21NTO 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 air exhaust duct. High heat-resistant door and fiberglass wool insulation provides effective sealing.
