Glas-Col's combination heating mantles have always been the mantles of choice for repetitive extracting, refluxing, and distilling procedures in labs of the food, textile fiber, water and waste-water, petroleum, and many other industries. The ideal mantle for Kjeldahl, Soxhlet, and other extraction procedures. Lower profile for space-saving convenience. Revolutionary heating element container system makes replacing burned-out elements a simple, five minute task. Element containers act as spill containment chambers to capture chemicals from spillage or boil-over. Clear anodized aluminum cabinet with black PTFE resin coated top for chemical resistance. This is a three-place version designed for 500-1000 mL flasks. See H1520 for a six-place version that fits 100-300 mL flasks. Available in low-temperature 400°C (752°F) RX version and high- temperature 600°C (1,112°F) RJ version. Two Series RL control choices are available: percentage timer or proportional voltage. The percentage-timer version pulses full-line voltage to each heating position according to the dial setting. The proportional-voltage version supplies a constant, steady-state voltage to each position. The cord-connected controls allow placement at a convenient location for the operator. Order controller separately. Note: 240V units are not returnable.
