Microcalorimetry Station
Description
Biochemical characterizations by measurement of heat exchange in microvolumes.
Technical specifications
- Based on an isothermal microfabricated calorimeter with a planar differential conduction, 50 Cr / Ni junctions of 1 cm length on a quartz of 200 μm thick
- Measurement on drops of 1 to 20 μl or well of a few tens of μl
- Surface or volume measurement
- Sensitivity: 0.675 V / W
- Integrated electrical calibration
- Piloted by Labview via an NI cRIO module with thermopile voltage measurement by a Keithley 2182A nanovoltmeter
- Installation in a closed cabinet with temperature control of the substrate by a Peltier element
Examples of available processes
- Evaporation and dilution enthalpy measurement
- Microtitration
