DCAT 21 tensiómetro, ángulo de contacto dinámico

DCAT 21
The dynamic contact angle measuring instrument and tensiometer DCAT 21 is the all-purpose instrument for the weight-based measurement of contact angle, surface and interfacial tension, critical micelle formation concentration, density, sedimentation and penetration rate, plus penetration resistance. Besides this it allows the use of the optional electrical temperature control unit TEC 250/DCAT, due to the 30 mm longer travel for the sample stage than the DCAT 11 and DCAT 11EC.

Features of the basic instrument configuration:
* High-precision electro dynamic compensation weighing system (weighing range: 10 µg to 210 g) with automatic calibration. * Software controlled height positioning (travel: 105 mm; resolution: 0.1 µm) of the sample receptacles with variable speed (0.74 µm/s to 500 mm/min). * Automatic electronic coupling lock for the balance. * Integrated measurement and control electronics with connections for two Pt 100 temperature sensors (-60 to +450 °C; ± 0.01 K resolution; precision 1/3 DIN IEC 751, Class B). * Display for weighing data, temperature and other information. * Illuminated sample chamber with inert gas or vapour inlet. * USB interface with connection cable to PC/notebook.
All DCAT accessories can be used with the DCAT 21, including the electrical temperature control unit TEC 250/DCAT.
