TGA701 Thermogravimetric Analyzer

Mass Loss as Moisture, Ash, Volatile Content, or Loss-on-Ignition 

Thermogravimetric analysis is the basic analysis in many industries to determine material weight loss as a function of temperature in a controlled environment. To meet the needs of these industries, the TGA701 Thermogravimetric Analyzer was designed for increased reliability and functionality. Expanded operational controls improve temperature accuracy across the entire range (up to 1000°C), while a pneumatic carousel assembly improves reliability by eliminating oscillation and increasing position accuracy for automation. PC-controlled operating software also supports compliance to 21 CFR Part 11 for a closed analytical system.
