Attension® Sigma Force Tensiometers

Attension® Sigma Base

The Attension® Sigma Base is a straightforward, manual force tensiometer for simple and cost-effective surface tension, interfacial tension, and liquid density measurements. With a digital balance for dependable accuracy and fully standalone operation, Sigma Base delivers essential performance without added complexity.

Simple by Design

Sigma Base’s manual operation and intuitive interface mean there is no software to configure and no steep learning curve, making it a practical choice for labs that need reliable tensiometry without added complexity.

Digital Accuracy

Operation is manual, but accuracy is not compromised. A digital balance produces fast, repeatable results for surface tension, interfacial tension, and density measurements.

Product Features

Manual Operation with a Digital Balance

Sigma Base’s digital balance supports measurements with both the Wilhelmy plate and Du Nouy ring. For Du Nouy ring measurements, Huh-Mason, Zuidema-Waters, and uncorrected results can be obtained, giving users the established correction methods needed for reliable surface and interfacial tension data.

Easy to Use

An intuitive user interface makes operation straightforward and results are immediately visible on the instrument’s screen. These guided workflows paired with dependable and robust hardware help new users learn the fundamentals of tensiometry while executing standard measurements with repeatable precision.

No PC Required

Sigma Base is a fully standalone instrument with no need for an external PC. When data needs to leave the instrument, a simple data receiver software allows easy transfer of measurement results to a computer. Convenient PDF reports summarizing the experimental data can be transferred from the Sigma Base instrument to the user’s device for quick decision-making in the lab.
