Overview

A Reliable Surface Tension Tester for Everyday Lab Work

The K6 is a precision laboratory instrument built for reliable measurement of surface tension and interfacial tension in liquids. It suits routine testing, research, and educational demonstrations, using the proven Du Noüy Ring Method to deliver consistent, accurate results.

A Dependable Laboratory Tensiometer

Ideal for laboratories, universities, research institutes, and industrial quality control departments, this instrument evaluates the effectiveness of emulsifying agents, wetting agents, detergents, soaps, lubricants, oils, and fuels. Its simple manual operation and robust build make it a preferred choice for teams needing dependable surface tension analysis. Browse our full range of surface tension instruments to compare models.

A Precise Interfacial Tension Meter

Beyond routine surface tension testing, the K6 is highly effective at spotting oxidation and polymerisation in organic and inorganic oils, lubricants, fats, petroleum products, and fuels — a versatile analyzer for quality control, product development, and research. Its measuring principle follows the classic Du Noüy ring method, a technique still widely referenced in analytical chemistry today.

Measuring Principle

How the Du Noüy Ring Method Works

This instrument follows a simple, internationally recognised three-step principle rooted in the physics of surface tension.

Step 01

Ring Immersion

A calibrated platinum-iridium ring is lowered into the liquid sample so it sits just below the surface.

Step 02

Controlled Withdrawal

The ring is slowly raised, pulling a film of liquid upward until the film reaches its breaking point.

Step 03

Dial Reading

The maximum force recorded on the calibrated dial gives a direct surface or interfacial tension reading in mN/m.
