Attention: Before initial use, run oven at 400°F without vacuum for 15 minutes to burn off any residue that may have been introduced during the manufacturing process.Now with our new low proportional gain temperature controllers, designed specifically for a very steady heating rate and optimal accuracy, at temperatures as low as room temperature and as high as 480°F, with +/- 1°F accuracy, the VO-16050m series digital desktop vacuum oven features a 1.9 cubic feet easy-to-clean stainless steel chamber with a large tempered glass safety window and small bench footprint. These ovens can greatly reduce drying time by maintaining a consistent vacuum level within the chamber.Every one of our vacuum ovens goes through a 24-hour vacuum leak test before leaving our factory.Features * Best choice for the curing and converting of oil extracts. With deep vacuum level, they can operate at temperatures which allow the degassing/purging process to occur rapidly, thus increase productivity and allow for the production of superior quality products with minimal processing time * Corrosion resistant stainless steel interior finish with dual-layer toughened glazing 12mm observation window * Overheat protection automatically cuts power when temperature is beyond limit or sensor fails * Digital temperature controller with timing, alarm and memory functions * Silicon door sealing gasket and adjustable door latch maintain great vacuum level and keep the outer surface of the oven from becoming too hot to touch * Racks included: 2 (maximum 5, additional racks available at extra cost) * Optional vacuum pump required for vacuum operation * One year warranty and lifetime US-based parts and service support.
