EDTA tubes are used for determinations blood for haematology, immuno-haematology or for the molecular biological identification of viruses, parasites and bacteria after centrifugation and plasma for clinical chemistry.
The additive potassium EDTA (Ethylene-diamine Tetra Acetic Acid) contained in the tube interferes with calcium.
A calorimeter is a device used for estimates the heat of chemical/ physical change.
The device is also capable of estimating heat capacity of a chemical.
Calorimeters are made of copper because copper is a good heat conductor, has a low specific heat capacity, and a light copper wall receives/delivers negligible heat.
