Surface Tension Balance Jaeger

Jaeger's Surface Tension Apparatus (Surface Tension Balance)

Jaeger's Surface Tension Apparatus is a laboratory instrument for determining the surface tension of liquids by the maximum-bubble-pressure (Jaeger's) method. Atico India manufactures, supplies and exports this surface tension balance to schools, colleges and universities worldwide, with all glass parts made from Corning glass for durability and chemical resistance.

Product Overview

The apparatus is convenient for determining relative surface tensions, or — after calibration with a liquid of known surface tension — the absolute surface tension of an unknown liquid. It is supplied complete with a tap funnel with ground-glass joint to fit the filter flask, a side-arm manometer, a beaker that serves as the bath, a tube with stirrer, and three jets of different sizes. All glass parts are made from Corning glass.

How Jaeger's Method Works

Air is admitted slowly through the tap funnel so that a bubble forms at the tip of a fine jet immersed in the test liquid. As the bubble grows, the pressure rises to a maximum just before the bubble breaks away; the side-arm manometer records this maximum pressure. Because the maximum bubble pressure is directly related to the surface tension of the liquid and the radius of the jet, the surface tension can be calculated — or compared against a calibration liquid. Using three jets of different sizes lets students check consistency and improve accuracy.

FAQs

Q. What method does this surface tension apparatus use?

A. It uses Jaeger's maximum-bubble-pressure method, measuring the maximum pressure needed to form a bubble at a jet immersed in the liquid.

Q. Can it measure absolute surface tension?

A. Yes — after calibration with a liquid of known surface tension. It also measures relative surface tension directly.

Q. What is it supplied with?

A. A tap funnel with ground-glass joint, filter flask, side-arm manometer, beaker bath, tube with stirrer and three jets of different sizes, with all glass parts in Corning glass.

Q. Do you supply in bulk for colleges?

A. Yes. Atico India offers bulk and tender pricing and can supply a matching set of physics apparatus. Request a quote with your quantities.
