This session will focus on the Attension Picoliter Dispenser, which enables sessile drop contact angle measurements on samples with small surface areas, thin wires, single fibers, and more. Based on piezo-driven inkjet printing technology, the Picoliter Dispenser can dispense droplets as small as 20 picoliters, resulting in drop diameters less than 100 µm, depending on the contact angle formed. We will explore how to set up the measurement, considerations for using this unique accessory, and demonstrate experiments on various materials.
