Introducing the new Ai UL/CSA certified AccuTemp1.9 cubic foot vacuum ovens, this certification is required by many municipalities, and it also provides a higher standard of equipment safety and lifespan. Also come standard is the secondary over-temp protection dial, all stainless steel tubing/compression fittings, stainless steel vacuum/vent valve, oil-filled vacuum gauge, 5 sided pad heating technology and two year warranty. The thermal-conductive aluminum shelves provide excellent temperature uniformity inside the chamber, while our 3rd gen LCD low proportional gain temperature controllers keep your oven temperature within +/- 1°F accuracy, in either °F or °C. 5-shelf ovens are recommended for initial stage of solvent evaporation process; 10-shelf systems are recommended for second stage (after extract has "muffined").
