These Classic Kjeldahl Digestion Apparatus provide macro digestion for nitrogen determination of samples up to five grams. Six-Place Models are able to digest up to six samples at one time. Two-Place Models are able to digest up to two samples at one time. The Two-Place unit offers the same rugged construction as larger Kjeldahl models, plus it is compact and may be placed inside a fume hood. Choose units with Water Ejector Systems for fume removal.

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.

The Labconco RapidStill II provides automatic steam distillation for macro Kjeldahl nitrogen determinations. Compactly designed to fit on bench top. Each distillation takes five to ten minutes. Frame is constructed of epoxy-coated steel.
Photo of Labconco RapidStill I
RapidStill I. Provides distillations for nitrogen determination. Designed for labs that are determining micro quantities of protein/nitrogen or performing one or two macro determinations per day by diluting and aliquoting the sample. Accepts digested samples up to 4 mL (max.) and gives reproducible results in ranges as low as 1 mg/L Kjeldahl nitrogen. A one-piece still is mounted on high-density polyethylene benchtop console that contains all operating controls. Each distillation takes only five minutes.
