SITA Science Line T100

The new SITA science line t100 is a mobile laboratory tensiometer for research and development as well as for quality control of products with surface active substances.

Using the bubble pressure method the tensiometer measure the surface tension of liquids within a large bubble lifetime range from 15 ms up to 100,000 ms.

The device automatically and acurately controls the chosen bubble lifetime without drift and complicated readjustments. The measuring results are presented numerically and graphically on a large color display.

The SITA science line t100 is a high-performance bubble pressure tensiometer that can be used for
• Analyzing the kinetics of surfactants in research & development
• Quality control through comparison with reference and limit values
• Automation of measuring and analysis tasks.
Due to its wide bubble lifetime range, liquids containing surfactants as well as other liquids can be measured within a large concentration range.

The following applications are examples for standard applications where surface tension measuring values are measured, compared and documented:
• Optimizing washing and rinsing processes in parts and textile cleaning
• Determining the wetting agent concentration in the electroplating industry
• Monitoring the Isopropyl-alcohol concentration in offset printing
• Quality control in ink production
