Labconco Rapid Digestors provide rapid digestions for nitrogen determination of 1 to 25 samples up to 2 grams using 250 mL tubes. Constructed of individual ceramic heaters surrounded by 1" thick insulation board housed in chemically-etched aluminum casing. A heater element is encapsulated in each heater module. An RTD platinum temperature sensor is encased in the ceramic and sends signals to the controller. Capable of reaching 410° C in less than one hour. Separate controller has power switch and a solid-state, stepless temperature control knob, factory calibrated from ambient to 450° C, with triac control of ¬±0.5% over entire operating range. Features a 6-foot electrical cord with plug and electrical lines to connect the digestor to the controller.

The RapidStill II (N1196) is the perfect companion to the Rapid Digestor. Operation inside a fume hood is strongly recommended.
