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.
• Electric distillation and digestion heaters with curved ceramic bases to cradle 500 or 800 ml Kjeldahl digestion flasks.
• Individual infinite-control knobs for electric heaters with variable input from 20-100% capacity
• Chemical-resistant CPVC fume manifold with heat-resistant PTFE nipples that draw chemical fumes from the digestion flasks.
• Full one year warranty

• Open Combination Units in 6-place and 12-place models
• Hooded Combination Units in 6-place, 12-place and 18-place models. Hooded models feature epoxy-coated steel construction reinforced with tubular steel and tempered safety glass, horizontal-sliding sashes. Three collars are provided for connection to remotely-located acid fume and hood heat exhaust blower and optional auxiliary-air blower.
• Various electrical configurations

• Kjeldahl digestion flasks
• Remote exhaust blower
• Ductwork

• Auxiliary-air blower (Hooded models only)
• Laboratory Carts and Benches
