Product Description .

Brief Description of chemical glass reactor

Lanphan S212-50L double-layer glass reactors reaction flask volume is 50L, interlayer volume is 12L, stirring diameter of axle is 12mm, power of stirring is 120W. S212-50L double-layer glass reactor is an audacious product who has combined advantages of domestic and foreign like products, it adopts double-layer glass design, put reaction solvent in internal layer to do stirring reaction, connect different cold and heat sources(refrigerating fluid, hot water or hot oil) to interlayer to do cyclic heating or cooling reaction. Under set constant temperature condition, you can conduct stirring reaction under normal or negative pressure in airtight glass reactor, as well as conducting backflow and distillation of reaction solution. S212-50L double-layer glass reactor is an ideal pilot test and production equipment for modern fine chemical engineering, biological pharmacy and new material synthesis. This glass reactor series mainly contains following parts: double-layer glass reaction kettle, a set of component cover of glass reactor, condenser, constant voltage funnel, frequency conversion controller, rotate stirring and sealing system, stainless steel frame system, etc.

Product features of S212-50L double-layer glass reactor:
1.Constant rotate speed, no electric brush, no spark, safe and stable, enable continuous working.
2.Full set of glass part is produced by G3.3 borosilicate glass, owns excellent chemical and physical properties.
3.When glass interlayer connecting to hot oil and been circulated, it can do heating reaction, connecting to refrigerating fluid can do low temperature reaction.
4.Enable reaction under normal temperature, that is connecting to tap water can take away the reaction heat quickly.
5.Enable reaction under normal temperature, that is connecting to tap water can take away the reaction heat quickly.
6.Discharge outlet has flange mouth and PTFE valve, there has no dead angle in vessel, detachable and convenient for solid material to discharge.
7.Main body is made from stainless steel, which is beautiful and anti-corrosion.
8.Sealed by PTFE component, be able to maintain higher vacuum degree.
9.Be able to work under normal and negative pressure, negative pressure up to -0.09MPa.
10.Alternating current dynamo conducts frequency control stirring, reliable operation, large moment of force and no spark.
11.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.

Q: What kind of payment term do you accept?

A: Normally we accept TT, Paypal, Western Union, Alibaba Escrow, and L/C. The exactly term with be discussed during the deal.

Q: Whats the loading capacity of double-layer glass reactor?

A: Loading capacity of glass reactor generally is 1kg, use hot water and oil to do negative pressure heating.

Q: Whats the difference between single-layer and double-layer glass reactor?

A: Single-layer glass reactor can directly heating or cooling, it is similar to water or oil bath, inferior in temperature control aspect; while double-layer glass reactor has interlayer between two layers, we can inject water or oil through temperature control equipment and form circulating system, in this way, no matter cooling or heating, its temperature control property is better.
