Kruss DSA20E Easy Drop Goniometer/Contact Angle Measurement

Description

The Kruss Easy Drop goniometer is used to measure the contact angle of a droplet in contact with a solid surface. The shallower the contact angle the greater the wettability of the drop. The goniometer utilizes a backlight and a high-resolution camera to examine and photograph a sessile drop which has been dispensed by a precision syringe with resolution in the µL range. The high-resolution camera captures an image of the drop and the contact angle can be measured from the captured image. The surface tension in air can also be calculated by discharging enough fluid to produce a pendant drop emanating form the syringe.
