Economical OAKTON® StableTemp® ovens are ideal for industrial, educational, bacteriological, and clinical labs on a tight budget. The gentle gravity convection airflow is important for samples that should not be disturbed by air currents. Low-watt coil heaters provide uniform heating at peak energy efficiency. Temperatures up to 200°C with uniformity of ±10°C for even heating. Temperature range is regulated by a hydraulic temperature controller that prevents heater element burnout. Durable, double-walled construction and thick mineral-wool insulation prevent temperature drift. Carbon steel interior, heavy-gauge welded steel exterior and powder-coat paint finish resist chemical damage. Each oven includes a spirit-filled glass thermometer for quick check of temperature and a 6-ft. three-wire line cord (120 VAC models include plug). Two adjustable shelves are also included; order additional shelves separately to increase capacity.
