The Attension Theta Lite optical tensiometer is uncomplicated, no adjustments needed, ready to perform measurements. Packed with smart features including an automatic disposable tip dispenser to eliminate the need to clean the dispenser between samples.
The camera on the Theta Lite optical tensiometer features a camera capable of capturing extremely fast wetting phenomena up to 2068 frames per second and performs exceptionally precise drop shape analyses with 1280 x 1024 pixel resolution. Droplet volume is calculated from the real-time image with advanced machine vision to ensure the droplet volume is the same each time to minimize variation. The instrument comes with a manual sample stage and an automated or manual liquid dispenser, making it a convenient entry-level instrument for research, industrial processes and educational use.
- Incredibly easy to use: Theta Lite is controlled with OneAttension software that has been designed for extreme user-friendliness.
- Packed with smart features: The automatic disposable tip dispenser ensures you don’t need to worry about cleaning as droplets are created precisely using a disposable pipette tip. The droplet volume is calculated from the live image with advanced machine vision to ensure repeatability.
- Powerful camera with software controlled autofocus: The Theta Lite camera captures the extremely fast wetting phenomena up to 2068 FPS and performs exceptionally precise drop shape analyses
