and Automated Lab Reactors
The use of Reaction Calorimetry over the past 30 years for the optimization of chemical processes is a success story.
Countless chemical processes have been examined closely and the in-depth process knowledge gained has save costs in many processes and thus repaid the initial investment in the Reaction Calorimeter. As METTLER TOLEDO Reaction Calorimeters range from a few milliliters to 18 liters reaction volume - using single reactor and multiple reactor systems, the Reaction Calorimeters cover the entire field of process development. Today, the RC1e Reaction Calorimeter is the proven industrial standard in both the chemical and pharmaceutical industries, and continues to enjoy success around the world.

1975: WFK75 Reaction Calorimeter
In 1975, the first Reaction Calorimeter was manufactured in large numbers by CIBA in Basel, Switzerland. The WFK75 Reaction Calorimeter was designed to run accurate and reproducible chemical and physical reactions in the Liter scale using an analog controller. The data obtained from the WFK75 Reaction Calorimeter enabled chemical engineers to successfully perform safety investigations, optimization and scaling up of chemical processes.

1981: BSC81 Bench Scale Calorimeter
A second series of computerized (PDP) instruments was produced in 1981, also in Basel, in the form of the computer controlled BSC81 Bench Scale Calorimeter. For the first time ever, the BSC81 Bench Scale Calorimeter allowed the user to store data electronically and to calculate thermodynamic parameters by means of an electronic device; this was the first step towards the user-friendly, computer-controlled Automated Lab Reactor (ALR) system for which the RC1eTM is known.
