DZF-6050-HT High-Temperature 53L Vacuum Oven with Digital Control, Inert Gas Flowmeter, and Water-Cooled Door Seal
DZF-6050-HT is engineered for laboratory heat treatment processes requiring precise temperature control under vacuum or inert gas atmosphere. Its 53-liter stainless steel chamber accommodates samples up to 16.3″×13.5″×14.5″ and supports continuous operation at temperatures from 50°C to 450°C, with short-term capability up to 500°C for less than 8 hours. This oven is ideal for applications such as drying, curing, and heat processing of materials sensitive to oxidation or contamination.
The oven maintains vacuum levels below 0.05 torr at room temperature and can operate at pressures under 5 psig. It integrates a digital temperature controller with 50 programmable segments and ±1°C accuracy, ensuring precise thermal profiles. A built-in flowmeter allows controlled purging with inert gases at flow rates between 50 and 500 ml/min, enhancing process atmosphere control. The door features a silicone gasket with water cooling to maintain seal integrity at elevated temperatures, supported by optional recirculating water chillers. The chamber includes two stainless steel shelves and a KF25 vacuum port for connection to vacuum pumps (sold separately).
