Quality control of foam

Whether you love foam or want to leave it, learn why it's a puzzle that can be solved

 

The dynamic nature of bubbles presents a world of possibilities

 

Foam is versatile, making it widely useful, but also sometimes a challenge to control. The ability to accurately measure its characteristics puts quality specialists in the driver’s seat to make data-driven improvements throughout the process – whether foam is the end product, a necessary byproduct or even an unwelcome side effect.

Foam analysis

All-around scientific characterization of foam | DFA100

Foam in everyday products as well as technical applications appears in manifold forms and is often produced on purpose, but can also be undesired. Our Dynamic Foam Analyzer – DFA100 helps to optimize foam for specific uses or to identify methods to effectively avoid it. The DFA100 characterizes almost every aspect of foam, such as foamability of liquids, the stability of foam, its liquid content, and even the number and real size of its bubbles.

Automatic Ross-Miles foam analysis | RMFA

The Ross Miles Foam Analyzer – RMFA is the world‘s first instrument for automatic measurements of foamability and foam stability in accordance with ASTM D 1173. Thanks to narrowly observed measuring times as per Ross-Miles and a height resolution of 0.4 mm, analyses in accordance with the standard achieve precision and repeatability that was previously unheard of.
