Contact angle, θ (theta), is a quantitative measure of wetting of a solid by a liquid. The behavior of single drop on a surface tells you a lot about the…
The Picoliter Dispenser is based on piezo-driven inkjet printing technology, and can dispense droplets as small as 20 picoliters. With a volume this small, a drop diameter of less than 100 µm is possible, depending on the contact angle formed.
The Theta Pico leverages the Attension Theta Flow‘s hallmark automation capabilities to remove user-dependent variation in contact angle measurements, enabling each experiment to be repeated with a high level of precision.
- Can be used to measure the contact angle even on the smallest surfaces of less than 100 µm.
- can create droplets as small as 20 pl.
