Rapid and easy measurements


On point

Our GSA PT 10 product line is built upon the standard Linseis microbalance design. This highly sensitive microbalance comes in two versions, offering exceptional precision with a sensitivity of 0.1 or 1 microgram for sample weights of 5, 25, and 35 grams.

For versatile operation, we provide a range of environmental chambers, enabling testing across a wide temperature spectrum, from as low as -150°C to as high as 1600°C, and under ultra-high vacuum conditions up to 10 bar.

Additionally, you have the option to enhance the capabilities of the system with a TG-DSC (Thermogravimetry – Differential Scanning Calorimetry) measuring head. This feature allows for the simultaneous determination of weight changes and calorimetric reactions in a single test run. 

To further expand the system’s capabilities, we offer optional gas and vapor dosing systems, as well as residual gas analysis. This versatility enables you to work with a variety of vapors and gases, including alcohols, hydrocarbons, aromatics, hydrogen, water, oxygen, nitrogen, argon, carbon oxides, and more.
