Description

• Independent heat controller lets you adjust the temperature range of each mantle individually
• Stainless steel construction is rugged and easy to clean

Run several projects simultaneously using these multiposition macro-kjeldahl extraction heaters. Heaters are available with two or six individually controlled heating mantles that accommodate either 100 to 300 mL vessels or 500 to 800 mL vessels. Back-mounted brackets hold flask support rods up to 12.7 mm in diameter.

Each mantle has an independent heater with control dial, on/off switch, and indicator light, and operates to a maximum element temperature of 800°C. A quartz heating element is housed in a thermally insulated cartridge for easy replacement, extending the life of the heater. Heat controllers located in the lower part of the unit is safely separated from the upper heating elements by a stainless steel tray and well-ventilated air space. Extra safety features include an earth screen and double fuses on the supply line.
