Radleys (Saffron Walden, UK) have introduced a revolutionary new Calorimetry module for their Lara Controlled Laboratory Reactor (CLR) system that sets new standards in accuracy, repeatability, operational flexibility and ease-of-use.

Calorimetry is a valuable tool for the process chemist. Unfortunately, traditional calorimetry techniques have many drawbacks. Coflux™ or Constant Flux Control is a new form of Calorimetry offering high levels of performance and flexibility at a low price. The Lara Coflux™ system provides real-time information on power and enthalpy readings without relying on any time-consuming baseline calibrations. The new system not only accurately produces heat of reaction and maximum heat flow data needed for hazard assessment to scale-up a process to pilot plants or production units but also generates the information for process monitoring, analysis and optimisation.

In traditional calorimetry temperature control is usually provided by altering the temperature of the coolant fluid. This leads to slow response times, dependency on a baseline calibration and thermal lag issues. Using constant flux calorimetry technology the temperature control is provided by a series of coolant pipes that can be opened and closed on demand. The use of this innovation massively improves thermal response and removes any dependency on the heat transfer coefficient of the system. The result is the first high performance laboratory calorimeter that is simple-to-use, accurate, fast and affordable.

Unlike do-it-yourself CLR systems, Lara delivers a complete integrated solution, with hardware and software components that have been specifically designed to provide optimal performance and reliability. The Coflux calorimetry module utilises the existing Lara CLR software, enabling easy integration of other Lara modules and third party equipment. System data is provided in real-time using an intuitive and flexible graphical display with all data logged to CSV files.

The standard Lara system comprises a choice of easily interchangeable jacketed glass reaction vessels (500ml, 1 litre and 5 litres), integral stirrer and stand with an intuitive, easy-to-use PC control system to set-up and run experiments. The system also offers direct connection of sensors and the ability to control an unlimited number of third party devices via RS232 or analog input/outputs. The compact footprint of Lara minimises valuable laboratory space and allows the unit to easily fit into a regular fume hood.
