The level of automation has reached a new high

The camera has fully automatic autofocus to ensure that the image remains clear at all times; Automatic surface positioning, which can move the sample to different measurement positions; And use the industry-leading OneAttention software to automatically generate results. These characteristics have taken the automation of optical contact angle measuring instruments to a new level,Improved experimental accuracy while simplifying testing.

Accuracy and user independence (without human interference)

The camera resolution of Theta Flow is up to 5 million pixels, and DropletPlus technology is used for image enhancement. The sensor can track the surrounding environment (temperature, humidity) for good traceability. These features enable Theta Flow to provide highly accurate results, and reliable data has become a key component independent of user measurements.

Touch screen is easy to use

The embedded touch display screen first equipped in Biolin Theta Flow improves the user experience, making measurement preparation work super smooth to process. All steps from liquid absorption to sample replacement can be easily completed in a few seconds.

Theta FlowOptional attachments:

3DMorphology module:It can automatically measure the roughness and contact angle of the sample, and obtain the roughness corrected contact angle to study the influence of roughness on wettability.
