Force Tensiometer
Tensíío
The new generation tensiometer for liquid and solid surfaces
Theoretically, building a tensiometer is simple: putting a moveable sample stage underneath a force measuring device. But developing the best-in-class tensiometer is something completely different. It takes more than just using an utterly precise force sensor (which we did) and the sample positioning with the widest dynamic range (which we developed). It takes a change of perspective that focuses on the user and his task - you and your task. It takes the will to make your lab work as convenient, flexible, and time-saving as possible. We believe that Tensíío is that kind of instrument.

Tensíío video series!
Many tasks, one solution: Experience Tensíío in action!
Tensíío Instrument Demo | Introduction
This introduction is part of a growing video series about Tensíío. Watch application expert Dr. Andrew Mellor explain how the setup can be adapted to your specific task. Experience the method variety of the instrument as well as its features designed to make the daily lab routine as convenient as possible.
Tensíío Instrument Demo | Measuring Surface Tension
This part of our Tensíío video series again features Dr. Andrew Mellor, demonstrating how easy surface tension can be measured and applied in tasks such as detecting detergent residue on a surface in simple steps. Learn about best practices for reliable measurements and about supporting functions of the ADVANCE software, such as result validation with predefined quality limits.
Tensíío Instrument Demo | Measuring Interfacial Tension
Watch Dr. Andrew Mellor explaining the relevance of interfacial tension for industrial applications and demonstrating how to measure it in simple steps with the Tensíío. Using an everyday problem, i.e. mixing a salad dressing, Dr. Mellor shows how important this parameter is for the production and analysis of emulsions.
Tensíío Instrument Demo | Dynamic Contact Angle
In this video, Dr. Andrew Mellor demonstrates the Wilhelmy dynamic contact angle method with our Tensíío. Learn how this approach helps characterize anti-adhesive and easy-slip behavior of materials and see how easy it is to carry out and evaluate a Wilhelmy measurement with Tensíío and the ADVANCE software.
Tensíío Instrument Demo | Washburn Powder Contact Angle
Following an introduction to powder contact angle measurement according to Washburn, watch Dr. Andrew Mellor demonstrate a live measurement with Tensíío. He focuses on thorough sample preparation as a prerequisite for reliable result and then explains how the KRÜSS Washburn Direct method simplifies evaluation as well as the recognition of poorly prepared samples.
As fast or as slow as you need it – but always convenient
To save time before and during each measurement, the sample stage of Tensíío moves particularly fast while preventing premature sample contact using pre-programmed standard positions. Or it moves extremely slow with hardly any vibration if you need it to, for example when analyzing high-viscosity liquids. Measurement preparation is easy thanks to the spacious, perfectly accessible sample chamber and the built-in stirrer and temperature control. The large, integrated touch display simplifies operation and obviates any external control pad, thus sparing lab space.
Have full control over the temperature
Do you want to maximize reproducibility by keeping the sample temperature constant? Would you like to simulate thermal conditions of your process? Or do you even want to know the behavior of your sample over a wide temperature range? Turn you plans into action and equip your Tensíío with a software-controlled temperature control jacket. Measure in a wide range between -15 and 140 °C while the ADVANCE software quickly and automatically regultes the target sample temperature – even step by step for a complete temperature ramp in a single measurement run.
Use the versatility of 15 methods (and growing)
Tensíío comes with 15 different approaches of analyzing surface and interfacial tension, wettability, and many other properties of your liquid samples or your solid bodies, powders, or fibers. Each one is carried out automatically using prepared and adaptable programs in the ADVANCE software. Further methods, which can be added anytime later, are being developed as you read this.
Integrate a camera in your own methods
Even more is possible when the optional high-resolution camera records what happens at the contact area at the liquid surface. Measure the adhesion between a drop and a solid surface while analyzing the drop optically - or even create your very own method using the flexible and intuitive automation programming in ADVANCE as a toolbox.
Tensiometry becomes colorful
Sample chamber illumination for easier preparation may be familiar to you. What is surely new is a tensiometer signaling whether the measuring result lies within a certain limit using green or red light. This is just one of the many ways to incorporate tri-color illumination into your automated measurement sequence.
The tensiometer that grows with your tasks
Yes, there is this top-class, high-resolution force sensor. And there is the most accurate height detection for the sample stage and a large selection of methods. But maybe you only have one specific task that just requires moderate force precision within certain specifications. Or you may not want to analyze wettability, so there is no use of a height sensor. To make Tensíío the right solution for you - and the one adapted to your budget - there are countless options to customize the instrument. And it is always possible to upgrade Tensíío subsequently if your tasks grow. Just tell us what you need!
Made by users for users
When a product makes you say: “They thought of everything!”, then users have been closely listened to, or, as with Tensíío, were even involved in the development. Tensíío has all the small details that add up to maximum convenience. Take the bottom plate of the sample chamber, which can be easily removed for cleaning, for example. Or the electronic levelling assistant, which helps you set up the instrument properly. Or the removable side doors for comfortable access to the sample chamber. You can even equip Tensíío with an ionizer to automatically dispose of electric charges that otherwise often interfere with analyses of solid samples. All in all, we have taken care that working with Tensíío comes with a highly positive user experience.
Fully automated CMC measurement
Our specially developed Micro Dispensers equip Tensíío for measuring the critical micelle concentration (CMC) with the utmost precision. The surfactant concentration range is set up and then measured fully automatically.
