The Computrac 4000 XL is a thermogravimetric analyzer allowing high precision measurements of the dry extract of liquid, solid, granular or powder products.

Unlike desiccators using small diameter trays and halogen lamps, the Computrac 4000 XL has a large 5 inch (12.5 cm) diameter tray and a nickel-chromium heater allowing the temperature to be set between 25 and 275 ° C to + -1 ° C (temperature certified every 10 ° C from 50 to 270 ° C).

This technology provides unparalleled precision and incomparably better than desiccators: sample mass 100 mg to 40 g, solids content of 0.005% 100% with a resolution of 0.001%, repeatability 0.002%.

Integrated cooling system allowing measurements to be carried out quickly (time savings of around 25% compared to a system without cooling).

As an option, it is possible to take measurements under nitrogen scavenging, thus making it possible to carry out tests on flammable products.

It is possible to store in the internal memory up to 250 methods, last 1000 results, last 100 curves or to use the optional web server which allows unlimited storage of programs and results.
