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.
Applications
- Surface tension and interfacial tension measurement for wetting and cleaning agents, emulsifiers, or other surfactants
- Determination of the effectiveness and efficiency of surfactants by CMC measurement
- Wetting behavior of tablets, pharmaceutical active ingredients, and excipients
- Wetting of varnishes and paints
- Wetting and adhesion of coatings
- Development of cosmetic products
- Wetting properties of inks
- Wetting of fiber bundles and textiles, also for fiber-reinforced polymers
- Sedimentation and ductility of dispersions
- Analyzing surface modifications
- Adhesion at superhydrophobic surfaces
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. Speaking of which, no external thermostat or controller is required when we equip your Tensíío with integrated temperature control between -15 and 135 °C.
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.
