6-Place Open Combo Kjeldahl Digestion/Distillation Apparatus, Three Phase; 230 VAC, 60 Hz

Combines Kjeldahl digestion and distillation all in one unit ? saves space|Easy-to-read temperature gauge|Remote-control flow valve allows cooling water volume adjustment|Counterflow heat exchanger controls back pressure, maximizes rate of distillation|Chemical-resistant CPVC fume manifold with heat-resistant PTFE nipples|Digest and distill up to 6 samples at a time|1 year warranty|The open combination Kjeldahl apparatus features digestion and distillation components allow you to determine total nitrogen content within a variety of materials such as feeds, grains, soils, fertilizers, plant tissue, water, organic wastes, and food products. The units are supported by a sturdy, tubular steel framework, with the distillation apparatus mounted above the digestion portion. The distillation manifold is equipped with seamless stainless-steel tubes. No fittings or gaskets are required, eliminating potential leaks. To assure uniform results, the counterflow heat exchanger allows you to control back pressure and maximize the rate of distillation. The cooling water volume can be easily adjusted with the remote-control flow valve. Standard drain lines can be used since water discharged is not contaminated with corrosives. The connecting bulb separates liquid from vapors prior to the vapors entering the condenser. It effectively traps caustic mist that may carry over to the recovery solution. The one-piece borosilicate glass blub is equipped with an integral dual-baffle design. The one-piece borosilicate glass delivery tube features a long neck, round bottom, and thick walls to help eliminate pressure fluctuations in the distillation phase. To provide evenly distributed heat and faster processing of samples, the curved ceramic electric heaters follow the round base of the Kjeldahl flask. Heaters accommodate 500 and 800 mL flasks (not included). Two models are available with the capacity to digest and distill up to 6 or 12 samples at a time.
