Ring/Plate Tensiometer STA-1

Quick surface tensions with an easy available tensiometer
Ring and plate tensiometry belong to the classical methods for measuring the surface tension of liquids. The principle is to measure the weight of a meniscus hanging on a ring or plate. Our solution does not an extra force transducer as any accurate laboratory balance (better than 0.1 µg) is suitable to complete this instrument. Easy handling and operation with a modern Windows software. Both manual and automatic versions are available.

The density of a liquid can be measured as well by the immersion of a body of known volume.
STA-1

Instrument parts
laboratory balance (better 0.1 mg)
automatically motor driven movement of the ring or plate or manual movement by a linear stage
holder for a ring, plate or immersion body

The instrument allows the following measurements

- surface tension of liquids
- ring and plate method
- determination of density with an immersion body
- corrections factors after Harkins and Jordan
- contact angle measurements with the immersing plate technique
- easy to handle instrument and software
- also available as manual instrument
- use with any PC or laptop
