Quotation Request



This low-pressure reactor is ideally suitable for larger experimental runs. This low-pressure reactor is available in stainless steel. The usable volume of the reactor can be varied 20L, 30L and 50L using different reactor vessels.

The NR-20L/30L/50L low-pressure reactor is notable for its ease of handling. The reactor is closed using a quick closure. The reactor seal is established using a conical flange lock and O-ring seal of PTFE, FKM, or FFKM. The appropriate fitting inserts are available in stainless steel. A total of 7 connection options are provided in the lid, which can be selected from the following:
* Gas sampling
* Rupture disc of metal for the safe limitation of maximum pressure
* Pressure display
* Vent valve
* Dip-tube liquid sampling
* Thermocouple with dip-tube
* Exhaust hose

Temperature is regulated using a temperature probe which detects the inner temperature of the reactor in an immersion tube. A second temperature probe can optionally be used as an independent overheating safety. Appropriate stand systems are available.

* 20L,30L or 50L / 20 bar / 250℃
* With bottom drain valve
* Quick closure chain
* O-seal ring made of Viton®, PTFE or Kalrez®
* Temperature controlled by heating and cooling circulators from JULABO
* Stiring by magnetic clutch and separate drive
