5.Main body is made from stainless steel, which is beautiful and anti-corrosion.

6.Sealed by PTFE component, be able to maintain higher vacuum degree.

7.Be able to work under normal and negative pressure, negative pressure up to -0.09MPa.

8.Alternating current dynamo conducts frequency control stirring, reliable operation, large moment of force and no spark.

9.The inner core of stirring rod is made from 321 stainless steel, strengthened anti-corrosion property, military technology makes workmanship more exquisite, operation with high proficiency.


YuHua Instrument SF-2L double-layer glass reactor is an ideal equipment for modern chemistry sample, petrochemical engineering, pilot experiment, biological pharmacy and new material synthetic.
