Calibration standards


Contact angle standard for the Young-Laplace method

  • Bookmark

The CP3970 and CP3970C calibration standards each consist of a base for the MSA with an inserted glass plate to which drop contours with contact angles of 30°, 60°, and 120° are lithographically applied. The contours accurately follow the theoretical drop shape according to Young-Laplace and enable calibration of the contact angle measurement with an accuracy of 0.8°. The standard CP3970C additionally includes a certificate which confirms the high accuracy of the print.
