📢 New to Labokraft’s portfolio: the Hei-REACT modular reactor system
The usability of a reactor system is not determined during the reaction alone. Vessel changes, cleaning, connecting sensors and peripherals, or reconfiguring the system are often just as much a part of daily work — and can easily interrupt the workflow. Heidolph’s new Hei-REACT system focuses on these practical situations. Its modular design, ergonomic handling solutions and reactor vessels with consistent geometry from 100 ml to 5 litres support flexible configurations and more predictable scale-up. In our blog post, we show how the system is designed, which everyday reactor-handling challenges it addresses, and when it may be a good choice for a new or further-developed laboratory process. 👉 Discover the Hei-REACT system in our blog post.

Everyday Challenges in Reactor Handling

When routine tasks become more complicated than necessary.
Frequent vessel changes, setup adjustments and limited workspace can turn routine reactor work into a time-consuming process.
Switching vessel sizes, adapting the setup for new sensors, cleaning the system or moving it to another fume hood often interrupts workflows and requires significant manual effort.
During scale-up, changing vessel sizes or glass flange geometries can make even simple adjustments slow and complex.
In many laboratories, valuable working time is spent on setup changes rather than on actual research.
The result: more downtime, higher physical effort and increased complexity in everyday reactor handling.
Hei-REACT was designed to reduce these everyday challenges with a more ergonomic, flexible and modular reactor concept.

Typical Customer Challenges
Small obstacles. Bigger impact.
These challenges do not occur in isolation. Together, they increase downtime, physical effort and the complexity of everyday reactor work.
 Heavy overhead stirrer requires two hands
  Vessel changes interrupt workflows, consume valuable time, and is risky
  Cleaning and setup adjustments increase downtime
  Limited space inside fume hoods complicates handling
  Rising costs and long lead times require multiple reactor systems for different applications
  Complex cable system increases setup complexity and safety risks
  Hei-REACT was designed to turn these everyday limitations into a more efficient, flexible and comfortable workflow.
Hei-REACT combines a compact footprint with flexible handling in everyday laboratory work.
One reactor system. Built around your workflow.
UNIQUE EASE OF USE
Less effort. Less downtime. Less risk.
Because changing a reactor vessel should not require a toolbox but become a routine, meaning fewer handling errors and faster turnaround, our system Hei-REACT includes:
 spring-assisted telescopic rod(s) for ergonomic height adjustment
 swivel functionality of the telescopic rod(s) and positioning ring for a quick and flexible handling of the stirrer, the lid, and the whole set-up alignment
 one-hand operation is possible to facilitate the fast and intuitive set-up
 tool-free PEEK couplings for a connection within seconds instead of minutes
 draindown-manifold kit for a fast and clean thermofluid drainage and workflow
EASY SCALE-UP
Reduced complexity. Reproductible results.
Process teams are under increasing pressure to deliver scalable chemistry faster, more safely, and with greater confidence. Developing processes at a small scale while planning for reliable scale-up is a constant challenge. That’s why Hei-REACT system focuses on reducing the complexity by offering a range of various vessels:
 reactor vessel sizes from 100 ml to 5 liters
 single or double jacketed reactor vessels
 optimized geometry across all vessel sizes
 height-to-width ratio of 1.25:1 for straightforward scale-up
 reliable data, reproducible results, and reduced risk
INFINETELY MODULAR
One framework. Many possibilities.
Whether for chemical synthesis, pharmaceutical development, or biotechnology applications, our reactor system can be precisely tailored to your processes and requirements. Experience the next generation of laboratory reactors.
Starting with the Hei-REACT reactor framework as a basis for every application, the system offers:
 a framework base that can accommodate one or more telescopic rod(s) in various positions
 support for one or more reaction vessels and overhead stirrers
 excellent stability and unique ease of use thanks to the swiveling, spring-assisted telescopic rod
 integrated drip tray
Once you have chosen the reactor framework, we will be happy to advise and assist you in selecting the system components you need for your application in a fume hood or automated environment.
