kiloclave®- lab pressure reactor

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

Other materials, pressures & temperatures are available

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.

The modular setup of the kiloclave® system allows changing or upgrading for new tasks at any time.

A wide range of accessories for feeding of liquids, solids, gas, a fast action closure device and others like catalyst baskets etc. are available – talk to us to define the right setup for your specific need.

Customer references

"For carbonization, we have chosen the Buchi kiloclave Type 3E with a Cyclone 300 drive as stirrer agitator. The design of the reactor stand allows easy filling and emptying by single person. The individual components can be cleaned easily. Two stainless steel vessels with 0.5 liter and 5 liter are available as reactor vessels. For special reaction experiments in the acidic range by adding organic or mineral acids, a 1 liter reactor made of Hastelloy® is used."

"Our emulsion polymerization process is very difficult to simulate at the laboratory scale. The process runs at moderately high temperature and elevated pressure. High-shear agitation is critical to product quality. We have struggled to identify a pilot reactor that provided just what we need.  The available systems either cannot achieve the elevated pressure or are designed for extreme pressure, making them extremely bulky and costly. We had begun enlisting custom equipment manufacturers until we came across the Buchi kiloclave system, which was a good fit for us. With some simple, cost effective, customization, the kiloclave has proven to be the perfect pilot reactor for our process optimization."
