Trusted by customers worldwide.
Since 1987 we have designed and manufactured scientific instruments and automation software for chemists and biologists, with offices in the United Kingdom, the United States, China and India.
Founded in the UK
H.E.L was founded in 1987. Our head office, research and development, and manufacturing are based here.

Princeton, NJ 08540Reactor systems designed as one instrument
Vessel, jacket, stirring, dosing, sensors and the controller that runs them are engineered together, so they behave as one system rather than a collection of parts.
Every part has a reason to be there
Glass or steel vessels, overhead stirring, heated and cooled jackets, automated dosing and data capture, specified for the chemistry you are running.
Built to your requirement, not from a catalogue
Almost every system leaves our factory configured to a customer’s specification. Customisation is the business, not an option.
Nearly four decades of instruments for people who make things
H.E.L was founded in 1987 to build laboratory equipment that chemists actually wanted to use. Today we design and manufacture automated reactor systems, calorimeters, bioreactors and battery test systems, and the software that runs them, for pharmaceutical, biotech, chemical, battery and petrochemical companies around the world.
Our systems are used by customers all over the world and supported from offices in the United Kingdom, the United States, China and India.
Quality and environmental management systems independently certified by Citation ISO Certification.
The people behind the instruments
H.E.L is run by the engineers and chemists who design, build and service its systems. Behind every system is a team of specialists in engineering, manufacturing and service.
Engineering and design
Chemists, biotechnologists, and chemical, mechanical and software engineers, who specify and design each system around the customer’s process.
Manufacturing and quality
Every system is built, wired and tested before it ships, by a production team with decades of experience.
Sales, service and support
We sell and support systems all over the world, with installation, calibration, spares and training wherever a system is installed.

Explore →Four things we ask of ourselves
Insightful
We understand the science before we design the instrument.
Collaborative
Customers, engineers and scientists design systems together.
Tenacious
We keep going until the system does exactly what it should.
Proud
Our name goes on every instrument. We want it to be earned.
