Temperature-Controlled Heating Plate ECH-20/ECH-20D, 20 Positions (CAT#: STEM-AL2-0443-ZJF)

The ECH-20 and ECH-20D are microcomputer-controlled heating plates for wet digestion and acid evaporation. They can be used independently or as auxiliary heating devices before and after microwave digestion. Microcomputer control provides timed operation and programmed temperature ramps. Both models have a maximum power of 1600 W and a maximum temperature of 250 °C. The listed temperature-control accuracy for both models is ±1 °C. Each model provides 20 sample positions with a 34 mm hole depth. The ECH-20 uses a listed hole diameter of 31.5 mm, while the ECH-20D uses 39.5 mm. The two ECH variants therefore differ in heating-well diameter while sharing the same position count, temperature ceiling, power, and hole depth.
