Key Benefits

3 reasons to invest

One instrument for all your needs

Flexible at its core, this instrument gives you plenty of measuring possibilities. All neatly packed in our easy-to-use software. Add accessories and modules to match your needs.

Results you can trust

We know that high quality imaging is essential for high quality results. Therefore the Theta Flex camera has a resolution of 1984 × 1264 px with a maximum of 3009 FPS. Sophisticated algorithms record and analyze the contact angle and surface free energy for you, and you can follow the experiment in real-time.

Need for speed?

All steps of your measurements can be automated to speed things up in the lab. This way you can also avoid user dependency. The outcome will be more precise, and experimenting more smooth. Enjoy.
