Labconco - 2117613 - Six-Place Hooded Combination Kjeldahl Digestion/Distillation Apparatus
2117613
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. • 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 Options • 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 Required Accessories • Kjeldahl digestion flasks • Remote exhaust blower • Ductwork Optional Accessories • Auxiliary-air blower (Hooded models only) • Laboratory Carts and Benches See other products in some related categories (click to browse): Industrial & Scientific > Laboratory & Science > Food & Beverage Testing > Analytical Techniques > Kjeldahl Analysis Weight: 828.0 lbs Weight metric: 376.0 kg Dimensions: 49.75" w x 28.75" d x 88.25" h Dimensions metric: 126 x 73 x 224 cm Electrical: 230 V, three phase, 60 Hz, 21 amps Kjeldahl Digestion Fume Removal Method: Remote Blower Exhaust Product Subcategory: Classical Macro Kjeldahl Purpose: Combination Kjeldahl Digestion and Distillation Required Accessories: Kjeldahl flasks, PVC Remote Acid Exhaust Blower, Coated Steel Heat Exhaust Blower
