Beiyang Lixing Glass Distillation Device Chemistry Teaching Device

The following is a comprehensive analysis of the technical parameters, application scenarios, and purchasing suggestions for glass distillation equipment:

1. ‌Equipment structure and type‌

• ‌core componentUsually composed of a glass distillation column (filled with stainless steel step rings or Bauer ring packing), an electric heating tower kettle, a vacuum insulation layer, a reflux ratio controller, and a condenser, with some models integrating magnetic stirring function

• ‌special designThe double-layer glass structure can be combined with electric heat tracing to achieve vacuum insulation, suitable for heat sensitive materials; The vacuum distillation device improves the separation efficiency of high boiling point components through rotary distillation function

2. ‌Key performance parameters‌

• ‌temperature controlElectric heating power range 500-2000W, tower top temperature accuracy ± 1 ℃, some models support intelligent PID temperature control

• ‌pressure rangeFrom atmospheric pressure to -0.098MPa (vacuum degree), suitable for the separation needs of materials with different boiling points

• ‌processing powerThe capacity of laboratory level equipment is usually 0.5-20L, and the capacity of pilot equipment can reach 50L

3. ‌Typical application scenarios‌

• ‌Preparation of high-purity solventsIf ethanol is dehydrated to 99.9%, it needs to be combined with molecular sieve or azeotropic distillation technology.

• ‌Natural product extractionDuring essential oil distillation, it is necessary to control the reflux ratio (1:5 to 1:10) to prevent pyrolysis

• ‌Scientific research experimentUsed to determine chemical parameters such as theoretical tray number and equal tray height.
