Introduction: The SEHB-2000 integrated universal distillation instrument is a new intelligent distillation treatment device that integrates constant temperature heating, automatic distillation end point control and cooling water circulation according to laboratory distillation pretreatment operation rules. The instrument experiments on precision temperature control, automatic anti-back After the detection and certification of the distillation recovery rate of the measurement and certification laboratory, the results are accurate and reliable, and The recovery rate is over 95%. The instrument can be widely used in environmental protection, disease control, aquatic products, water supply and drainage, universities, research institutes, factories and mines and other chemical laboratories where distillation is required, such as volatile phenol, cyanide, ammonia nitrogen, Kjeldahl nitrogen Distillation treatment of water and other items and distillation experiments of sulfur dioxide residues in food. The receiving bottle is not restricted. Executive standard Water quality - Determination of volatile phenol - 4-aminoantipyline spectrophotometric method (HJ 503-2009 ) Water quality - Determination of cyanide - Volumetric method and spectrophotometric method (HJ 484 - 2009 ) Water quality Determination of Ammonia nitrogen Distillation-neutralization titration (HJ 537-2009) Soils - Determination of cyanide and total cyanide - Spectrophotometric method (HJ 745-2015) The distillation experiment can automatically stop heating, prevent back suction, internal circulation cooling mode, no external water source, fast distillation speed, high efficiency, no need for manual guard! Features: 1. The heating module is the only one in China that adopts imported far-infrared ceramic furnace, which has wide heating power adjustment range, high heat radiation efficiency, fast distillation speed and long service life (three years free warranty); 2. The distillation end point automatically stops the locking function, adopts the advanced weighing pressure sensor control, can set the distillation volume weight arbitrarily, automatically stop heating, sound and light alarm, automatically lock the distillate, the range 1-500ml; 3. The cooling method adopts closed internal circulation return system, no external cooling water source is needed, and it is equipped with compressor refrigeration + air-cooled double cooling and cooling internal circulation system, suitable for large-scale work, and the condensation effect Is good! 4. One-button internal circulation water tank adds water and stops automatically. Set anti-vacuum electronic valve, anti-back suction function, no need to manually guard! Technical Parameters: Heating method: Adopting Good, far-infrared ceramic heating furnace, infrared radiation heating, single hole power ≤800 (no open flame heating, waterproof, long service life) The heating program is equipped with a micro-boiling and full-boiling mode. The distillation speed can be selected according to the boiling point of different samples to ensure the safety and stability of the distillation experiment and prevention bumping. A gold-plated thermal insulation layer is placed on the bottom of the heating zone to prevent heat loss at the bottom. The heat radiation efficiency is high. LCD display: LCD display Heating unit: six groups, single hole single control Heating time: 5-8min Single hole power: 100-800W (single furnace, adjustable) Total power: 600-4800W (adjustable) Distillation speed: 2-12ml/min (the heating rate can be adjusted to adjust the distillation speed) Distillation end point control: Automatically detect the distillation end point by using the weighing sensor, can set the distillation volume weight arbitrarily, automatically stop, control accuracy ± 2ml Cooling method: closed internal circulation return system, no external cooling water source required Anti-back suction: with anti-vacuum solenoid valve, anti-back suction function Time control: 0-200min adjustable, can automatically stop heating by setting the distillation time. With six-way steam heating device, it can completely supply water vapor. Single hole single hole. Distillation flask Specifications: standard 500ml × 6; 250ml × 6 (optional) Receiving bottle specifications: standard 250ml × 6; 100ml × 6 (optional)
