Uncovering Scale-up and Safety Issues
OptiMax HFCal is a reaction calorimeter that generates calorimetric information under both isothermal as well as non-isothermal conditions. The system is Plug & Play and ready to run any desiged unit operation automatically - or manually if preferred.
Heat Flow Calorimetry ? Simple and Accurate
OptiMax HFCal reproducibly delivers information to characterize and scale-up processes ensuring they are safe at scale.
At the push of a button, iControl software automatically calculates heat data, including:
- Heat transfer coefficient
- Specific heat of the reaction mass
- Heat flow for isothermal and non-isothermal conditions
- Thermal conversion
- Adiabatic temperature rise
iControl Software creates a report including trends and tables of experimental results.
Heating and Cooling ? No Additional Cryostat Needed
Heating and cooling is fast and does not require a cryostat. The electrical heating and Peltier cooling ensure precise temperature control from -40 °C to 180 °C.
All events and data are recorded automatically, making experiments traceable and reproducible. At the end of the experiment, the relevant data is summarized and a report with tables and trends is generated automatically. For further processing, interpretation or storage purposes, iC Data Center or the Microsoft® Excel® can be used.
