Laboratory pressure reactor system - easy operation for heavy pressure vessels

Reactor volume: 0.5 to 20.0 liter
Pressure: -1 (FV) to +60 / 200 bar
Temperature: -20 °C to +250 °C
Material: stainless steel, Hastelloy®, glass-lined steel

This multipurpose pressure reactor system is designed for the use of large steel pressure vessels. The hydraulic vessel lift with tilt function makes opening and closing as well as cleaning of the vessel very easy. Safety features guarantee safe reactions under pressure.

The stainless steel or Hastelloy® reactors ensure high resistance against acids. Visual process control and monitoring is also possible under high pressure by using steel pressure vessels with sight glasses. Various low to high torque magnetic drives ensure efficient mixing and stirring low to high viscosity process media as well as excellent heat transfer.

Multipurpose glass reactor for small volumes

Glass reactor: 20 to 30 liter
Pressure: -1.0 (FV) to +0.5 bar
Temperature: -60 °C (optional -90 °C) to +200 °C
Material: Borosilicate glass 3.3, PTFE, PFA, PEEK

A clean-room setup and other materials are available to meet your specific process requirements.

The midiPilot is our sturdy multipurpose glass reactor for small volumes. It is specifically designed for applications in kilo lab, for chemical process development and cGMP compliant API syntheses.

The reactors' explosion proof design (ATEX) and inert materials allow safe processing of solvents and acids in a completely sealed reaction vessel.

The compact reactor system can easily be modified:  interchangeable reaction vessels of 20 and 30 liter including interchangeable stirrers are available. The glass reactor is equipped with a lifting / lowering device for easy and efficient opening and cleaning.

Nutsche filters for reactors and pilot plants

Glass vessel: 10, 30, 50, 100, 140, 300 liter
Pressure: -1.0 (FV) to +0.5/ 1.0 bar
Temperature: -60 °C to +150 °C (200 °C)
Filter cloth: Mesh size 8 to 115 micron
Material: Borosilicate glass 3.3, PTFE, PFA, ETFE

A clean-room setup and other materials are available to meet your specific process requirements.

Buchi nutsche filters can easily be combined with our reactors for solid / liquid separation after the synthesis. The inert materials allow safe processing in an inert atmosphere of a wide range of solvents and acids in a completely sealed (buchiflex) glass system under full vacuum.

The slurry is transferred into the filter. The solid content in the slurry is held back by the filter cloth forming a filter cake, while the filtrate runs away to the outlet valve in the bottom plate. The filtering stage ends when the filtrate is of small quantity, which can be shortened by squeezing the filter cake by turning the height adjustable stirrer.
