Reliant Lab Searles Surface Tension Balance for Educational Demonstrations and Industrial Coating Research

• Product Quantity : 1 Piece
• Stand Type : Tripod Stand with Levelling Screw

Features

• High Sensitivity Torsion Wire: Features a fine gauge wire that provides a linear relationship between the twisting force and the surface tension of the liquid.
• Micro Adjustment Leveling: Equipped with a precision threaded screw to slowly raise or lower the liquid vessel, ensuring a controlled contact and detachment phase.
• Integrated Pointer and Scale: Includes a clear, graduated circular scale and a non-corrosive pointer to measure the exact degree of torsion or dis placement.
• Robust Cast-Iron Stand: The entire assembly is mounted on a heavy duty, anti vibration base to ensure stability during delicate measurements.

Applications

• Educational Demonstrations: Used in undergraduate physics to verify the relationship between force, length, and surface tension.
• Surfactant Analysis: Measuring how the addition of detergents or soaps reduces the surface tension of water.
• Temperature Coefficient Studies: Investigating how surface tension changes as the liquid sample is heated or cooled.
• Purity Verification: Detecting impurities in solvents, as even trace contaminants significantly alter the "pull-off" force.
