H.E.L GROUP products

The Tandem gas analyser has been used by scientists and engineers for over a decade to understand the cells in their fermenters and bioreactors in more detail. Other gas analysis equipment, such as a mass spectrometer, may help you get the O2 and CO2 conentrations, however, the Tandem has been specifically designed for the fermentation industry and for ease of integration. We understand the equipment you already use, and how to benefit quickly from installing a new sensor. We can provide application examples, practical help and simple step by step guides for you, whether you run one or two 50ml mini-fermenters or a facility with multiple 100m3 manufacturing bioreactors. The Tandem has already been installed on all these equipment ranges, and on almost all manufacturers` models, meaning you have the benefit of a flexible and portable analyser. The accuracy and precision of the sensors inside the analyser are designed for fermentation processes and their process control equipment.

The Tandem PRO is a self-contained O2 & CO2 gas analyzer. The PRO system comes with an internal gas pump and programmable display. It includes calibration functions, error reporting and dual 4-20mA outputs. An RS232 output is included for integration into control systems.

The Tandem Mulitplex system is an economical choice for laboratory, pilot or production areas that have in excess of six fermentors or more. The multiplexed models have a local display, calibration functions, error reporting and selectable line control with an RS232 output for integration to control systems.

BioVIS allows the online monitoring of total cell growth and biomass using optical density, which can reduce or replace the need for online sampling.  BioVIS is a compact, portable unit compatible with all major brands of bioreactor. Simply insert the sterilisable probe inside the bioreactor and track growth kinetics.

Designed to maximize your laboratory’s productivity, parallel synthesis technologies with PolyBLOCK is easy to use, flexible and compact multi-reactor system. With either four (PolyBLOCK 4) or eight (PolyBLOCK 8) independently controlled and monitored zones, PolyBLOCK 4 offers working volumes of up to 500 ml and PolyBLOCK 8 up to 120 ml.  Reactor options range from 1 ml HPLC vials to round or flat-bottom flasks up to 250 ml and custom reaction vessels up to 500 ml. Agitation in each zone is independently controlled and temperature monitoring and control is offered with either reactor and/or zone temperature.

The ChemSCAN is a bench-top, automated parallel catalyst screening platform, designed for the rapid screening of high-pressure reactions and catalysts. The 4 reactor variant, supports reactors ranging from 16ml to 500ml. As with the fully automated ChemSCAN, each stirred reactor is independently controlled and monitored, allowing screening tests to be carried out concurrently and accelerating development time.

The FlowCAT is an automated high-pressure flow catalysis bench-top platform, designed for the development of continuous flow chemical processes. It supports both gas and liquid feeds, and so can facilitate the scale-up of both homogenous and heterogenous chemistries.

BioVIS is a probe for the inline monitoring of total cell growth and biomass within a bioreactor, enabling culture growth kinetics to be tracked and logged.  It removes or reduces the need for online sampling, thereby simplifying measurements, reducing contamination risks, and conserving the culture media volume.

H.E.L’s fully customizable AutoLAB reactor platforms are designed, configured, and tailored to meet your specific process and application requirements.  The modular and highly adaptable nature of the system enables the platform to evolve with your research and development interests.

The need to study crystallization is widespread in the chemical industry due to the importance of solids as the final form of many products. H.E.L’s CrystalEYES makes it easy for chemists to determine the crystallisation and dissolution points of their solutions.
