Pharmacopoeia 2020 Initial Tack Tester

Model: CBY-1Y

Purpose: Utilizes the inclined ball tack method to test the initial tack of samples by measuring the adhesive force between a steel ball and the adhesive surface of products like adhesive tapes and labels under slight pressure during brief contact. A steel ball is rolled over the adhesive surface of the tape placed on an inclined plate. The initial tack is evaluated based on the maximum size of the steel ball that can be adhered to by the adhesive surface of a specified length.
