Product description
Product parameters


  Sublimation instrument(Organic Small Molecule Purification Equipment) is to purify the organic mixture under vacuum conditions ( re-crystallization after evaporation). The main treatment object is sublimable organic material, or a mixture with mobile phase characteristics such as organic sound and light products (such as An organic photoelectric material for an organic light emitting display) or a nano material.

  BEQ provides a variety of sublimation instruments that meet the needs of R&D, pilot and industrialization levels, enabling users to seamlessly integrate from laboratory to production line.

  Adopt Vacuum adsorption ball head extrusion seal.The structure is simple and easy to disassemble. Convenient to put in and put materials also operate.
