Simular | Process Development Reaction Calorimeter
This highly configurable reaction calorimter that excels in optimizing process conditions and determining safer reaction conditions. With dual reactor options available, offering more flexibility for applications.
In addition to traditional heat flow calorimetry, the Simular offers power compensation calorimetry allowing operators to skip time-consuming calibration steps and get more conditions screened. The Simular is ideally suited for process safety and scale-up of the most varied and demanding reactions.

Overview
Simular is a flexible reaction calorimeter designed to measure reaction heat output and enthalpy, providing critical data for process development, optimization, and scale-up.
Accurate Measurement of Reaction Heat and Cooling Demand
By quantifying reaction power and heat release, Simular enables users to determine cooling requirements and assess process safety. It can also be used to estimate accumulation of unreacted material and potential adiabatic temperature rise.
Designed to Reflect Real Process Conditions
Built around a stirred, jacketed reactor, Simular allows precise control of temperature, feeds, and operating conditions. This enables realistic simulation of batch and semi-batch processes under laboratory conditions.
Flexible Calorimetry and Process Control
Supporting multiple calorimetry methods and a wide range of configurations, Simular adapts to different chemistries and process requirements. Its integration with probes, feeds, and automation tools provides deeper insight into reaction behavior.

My experience with H.E.L dates since 2005. During these years H.E.L was the provider of the most important lab equipment with the help of which I developed many different API pharmaceutical processes in the companies l worked for including Merck, Pfizer, and Theravance. The versatility of the automated lab reactors (AutoLAB), the ease of use of and the accuracy of the TSu and Simular systems, as well as the flexibility of the PolyBLOCK made my work much easier and accurate. I would like to mention the great relationship I established with the service engineers and the sales people at H.E.L. With their help I was able to customize the software and the hardware of the equipment to our specific needs. This readiness to accommodate each customer’s specific needs gives H.E.L the edge over their competitors and makes them the preferred vendor for pharmaceutical lab equipment.
