Thermogravimetric Analyzer - TGA Thermal Gravimetric Instrument - RT to 1150°C, 0.1-100°C/min

The Master Science Thermogravimetric Analyzer tracks the mass of a sample while it is heated, held at temperature or cooled, giving TG and DTG curves for material studies. This version covers room temperature to 1150°C with heating rates between 0.1 and 100°C/min.

The furnace of the Master Science Thermogravimetric Analyzer is double insulated for better linearity, and a tail gas outlet lets the instrument be coupled to infrared equipment. Operation is from the 7-inch touch screen or from a computer through two-way USB communication.

Common Problems This Analyzer Solves

Thermogravimetric work is easily disturbed; this design tackles the usual causes.

• Furnace heat disturbs the balance:: the main unit isolates the weighing system from the furnace.
• Evolved gases cannot be studied further:: a tail gas port allows connection to infrared equipment.
• Manual gas changes interrupt a run:: the gas path switches automatically in programmed stages.
• Long waits between samples:: air cooling brings the furnace back down quickly.
