Product Description

The S312-50L three-layer glass reactor is the newly developed glass equipment. The glass material is GG- 17. The frame is made of stainless steel. The reactor volume is 50L. The interlayer capacity is 13L. The exhaust valve height is 450mm. and the temperature range is - 80-250 ℃. The vacuum degree is 0.098 Mpa. The range of stirring speed is 0-280rpm. Stir in diameter of 12mm. The voltage is 220V / 50Hz. The device is a three-layer glass that forms two intermediate layers. It can be heated or cooled internally. The outside can be evacuated to maintain the reactor's heating or cooling temperature. When it is working, it can be stirred and can control the evaporation and reflux of the reaction solution. The reaction in the reactor is then released from the bottom discharge valve after the reaction. The operation is very convenient. It is an ideal equipment for modern chemical samples testing, petrochemical, bio-pharmaceutical and new materials. The S312-50L three-layer glass reactor meets the requirements of different experiment customers, saves experiment time and steps, and fills the gap in domestic equipment industry.

Product features of S312-50L three layers glass reactor:

  1. The equipment is sealed with PTFE and special rubber sealing ring to maintain high vacuum and solvent.
  2. Efficiency condenser ensures high recovery rate.
  3. Standard connection are easy to remove..
  4. Discharging valve makes solvent recovery very fast.
  5. The vacuum gauge can be used to select the best vacuum degree of low-boiling material.
  6. This machine adopts high quality stainless steel, aluminum alloy and new synthetic materials, corrosion resistance, rust resistance and various solvents.
  7. The glass component adopts GG17 glass to endure high temperature and good physical and chemical properties.
  8. The main electrical components are original imported parts.
  9. The machine adopts electronic stepless speed regulation, the motor has no spark, safe and reliable, long life.
