About science line t100 Bubble Tensiometer
The SITA science line t100 Bubble Tensiometer is a compact and high performance instrument for measuring dynamic surface tension and analysing surfactants.
It is a mobile instrument ideal for use in education, industrial laboratories and Research & Development, as well as for the quality control of products with surface active substances.
Similar to the Bubble Tensiometer T15 this instrument will measure the surface tension of liquids but within a larger bubble lifetime range from highly dynamic to quasi-static (15 ms up to 100,000 ms). The instrument will automatically control the chosen bubble lifetime accurately without drift and complicated readjustments. The results are presented numerically and graphically on a large colour display screen.
Measuring Principle
Measuring the dynamic surface tension with the bubble pressure method enables high precision and flexibility without difficult adjustment of the immersion depth. This is done by pumping air through a capillary into the liquid to be analysed. The pressure within the bubble changes continuously with its’ radius. The surface tension is calculated from the deviation between pressure maximum and minimum. The calibration is carried out automatically with water. Thereby the radius of the capillary is taken into account.
The Bubble Pressure Science Line T100 measures:
- Auto Mode Measurements through the whole bubble lifetime range
- Evaluating surfactant effects
- Analysing the kinetics of surfactants
- Characterising the wetting behaviour of surface active agents
- Online Mode Continuous measurement
- Measurement of temperature dependencies
- Analysing the ageing behaviour
- Evaluating the sample stability
- Single Mode Single measurement
- Control and test requirements
- Concentration measurements
Features & Benefits
Auto single, online mode- Bubble lifetime up to 100 s
- Access to 64 individually parameterisable methods
- Possibility of external gas supply and drying of the sample gas
- Laboratory automation with accessories
Users can also benefit from the new windows-based software “SITA-LabSolution” which will automate laboratory measurements and active ingredient analysis. The software is user friendly and offers a report function for creating measurement protocols and result analysis.
