Description

Open Combination and Hooded Combination Kjeldahl units have digestion and distillation components for nitrogen determination in one space-saving apparatus. Open Combination Kjeldahl units are supported by a sturdy, tubular steel framework, with the distillation apparatus mounted above the digestion portion. Models are available with the capacity to digest and distill up to 12 samples at a time. Hooded Combination Kjeldahl units enclose the distillation and digestion apparatus so that process heat may be contained and vented from the laboratory. The hood surrounding the apparatus includes three collars: one for remotely-located exhaust blower connection, one for acid fume exhaust manifold connection, and one for auxiliary-air blower inlet connection. Models are available that digest and distill up to 18 samples at one time. Kjeldahl units require a remote blower to exhaust fumes. Features Distillation manifold with seamless stainless steel tubing. No fittings or gaskets are required eliminating a potential leak source. Counterflow heat exchanger controls back pressure and maximizes the rate of distillation for uniformity of results. Remote-control flow valve allows cooling water volume adjustment. Easy-to-read temperature gauge located on the water outlet One-piece borosilicate glass connecting bulbs separate liquid from vapors prior to the vapors entering the condenser and effectively traps caustic mist that may carry over to the recovery solution. One-piece borosilicate glass delivery tubes with long necks, round bottoms and thick walls to help eliminate pressure fluctuations in the distillation phase.
