Rapid Digestors

By Labconco
Rapid Digestors

 

Available in 4- or 25-place models, the Rapid Digestors were developed in a working laboratory environment following extensive interviews with Kjeldahl users. Only Labconco’s Rapid Digestors provide an individual ceramic heater module for each tube to provide efficient, uniform heat transfer. Unlike aluminum block designs, the ceramic modules have virtually the same coefficient of heat expansion as the digestion tube. This means more rapid destruction of organic material resulting in faster digestions. Digestion time is normally 45 minutes depending on the sample type and catalyst. Each ceramic heater is insulated on all four sides as well as the bottom. This prevents heat loss and assures low energy consumption while maintaining reduced external housing temperatures.

Rapid Digestor-4 and Rapid Digestor-25 both provide rapid digestions for nitrogen determination of 1 to 4 or 25 (depending on model) samples up to 2 grams using 250mL tubes. Both models are constructed of individual ceramic heaters surrounded by 1" thick insulation board housed in chemically-etched aluminum casing. The Rapid Digestor-4 has 4 heaters, while the Rapid Digestor-25 has 25 along with two fold-down handles on the casing. A heater element is encapsulated in each heater module. An RTD platinum temperature sensor (5 sensors are in the Rapid Digestor-25) 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 Rapid Digestor-25 also has a 7-foot electrical line (electrical plug is required). Includes carrier rack made of aluminum alloy with two plastic handles and two removable heat shields.

Requires 250mL digestion tubes and fume removal system (not included). Operation inside a fume hood is strongly recommended. The RapidStill II provides the ideal companion for the Rapid Digestors.
