About This Product
Water let out of the aspirator slowly draws air through the capillary dipped in the test liquid, and the manometer shows the pressure at which each bubble breaks away. That maximum pressure gives the surface tension, so different liquids and concentrations can be compared. Schools, colleges and institutes in Belize, Uzbekistan, Brazil, Morocco and Sudan can order the Jaeger's Surface Tension Apparatus from Educational Instrument.
Frequently Asked Questions
Which method does Jaeger’s Surface Tension Apparatus use?
It uses the maximum bubble pressure method, reading the pressure on a U-tube manometer as bubbles form at a fine capillary.
