Compact, Fast and Highly Accurate

Microtrac’s BELSORP MR1 focusses on easy handling and the fast characterization of porous materials. This instrument is precisely designed to measure specific surface areas using dynamic BET (Brunauer-Emmett-Teller) single-point method. Measurement of the specific surface area utilizing BET theory is one of the most common analytical methods in material evaluation based on adsorption phenomena. Generally, the specific surface area of a sample is calculated based on the amount of nitrogen adsorbed at liquid nitrogen temperature. The amount of adsorption can be measured by different methods, e.g., volumetric (BELSORP MINI X or MAX II series), gravimetric or dynamic. The BELSORP MR1 make use of the dynamic method.

The BELSORP MR1 is a highly efficient, stand-alone device that allows simultaneous pre-treatment and sample measurement. Due to our highly sensitive thermal conductivity detectors (TCD), thermometers & pressure gauges, an accurate measurement result is achieved in approx. 15 minutes. The automatic Dewar movement, the calibration function and the operation via the touch panel make the BELSORP MR1 extremely user-friendly and suitable for inexperienced users.

The analysis results are calculated automatically as soon as the measurement is completed. After the measurement, the specific surface area is displayed without the need for tedious manual calculation. The respective measurement results (including whole lists ) can be transferred to a USB storage device, and are output as text files, Excel spreadsheets or printed report (rich text).
