Laboratory Furniture, Classical Macro Kjeldahl Apparatus, Combination Hooded

Combination Hooded Kjeldahl Apparatus
Open Combination and Hooded Combination Kjeldahl units have digestion and distillation components for nitrogen determination in one space-saving apparatus. The 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
Specifications

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 800mL 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

Fume Removal Method	Remote Blower Exhaust
Purpose	Combination Kjeldahl Digestion and Distillation
