A companion to the Micro Kjeldahl Digestor, the RapidStill I is designed for labs that are determining micro quantities of protein/nitrogen. It may also be used to perform only one or two macro determinations per day by simply 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 powder-coated steel benchtop console that contains all operating controls. Each distillation takes only five minutes. Features: built-in glass aspirator that purges spent samples after determination; one-piece borosilicate glass still with chemically-inert PTFE stopcocks; 115-volt immersion heater inside the water reservoir; variable heat control switch for controlling steam; and 8-foot, 3-wire cord with plug. Includes fill valve for filling the boiling flask, rear cooling water connections through the back of the housing, adjustable height shelf to support the receiving flask, water bottle for introducing distilled water to the boiling flask via the fill valve, and one large U clamp and two small U clamps to secure glassware. Dimensions (W x D x H): 14.5 x 9.8 x 24.4 in. Ship Weight.: 23 lbs (10 kg). Wired for 115 volt, 60 Hz, 2.4 amp operation.
