TGA 4000 Thermogravimetric Analyzer 

The TGA 4000 Thermogravimetric Analyzer features reliability, robustness, low cost of 

operation, and ease of use, all of which make it an outstanding analyzer for quality control 

laboratories. 

The TGA 4000 is controlled by Pyris software, installed on the computer to which the 

analyzer is connected. The TGA 4000 measures the weight of a substance as a function of its 

temperature or the time. Weight changes can be measured accurately, generating 

information on various processes in a sample such as dehydration, degradation, oxidation, 

etc. Also, since measurements can be performed in a well-defined atmosphere, the behavior 

of a sample in atmospheres other than air can be studied easily. The TGA 4000 can be used 

for component analysis (weight %), evaluation of stabilizers, loss on drying, proximate 

analysis, lubricating oil analysis, and oxidation studies. The information it provides is 

essential to industries such as plastics and polymers; automotive; semiconductors and 

electronics; adhesives; paints and coatings; fuels; ceramics, clays, and soil; food; 

pharmaceuticals; and medical devices and equipment.
