What is the method for conducting adhesion retention tests on medical adhesive tapes?

The ST107 holding adhesion tester is designed and manufactured in strict accordance with the requirements of the new 2025 Chinese Pharmacopoeia "0952 Adhesion Determination Method, Second Method: Determination of Holding Adhesion", and is suitable for holding adhesion testing of products such as medical adhesive plasters. It is mainly composed of a timing mechanism, test plate, loading plate, weights, frame and standard pressure roller. It uses a high-precision relay to control the timer for timing, equipped with a high-quality proximity switch and a built-in lithium battery for the timer, featuring convenient operation, high sensitivity and accurate timing.

Holding adhesion testing method: Hang the test plate with the sample vertically on the test stand, hang a weight of specified weight at the lower end, and determine the ability of the adhesive tape to resist detachment by the displacement of the sample after a certain time or the time required for the sample to completely detach.

Key technical parameters of the ST107 holding adhesion tester: The weight is 200±2g (500g optional), the test plate size is 125×125×2mm, the timing range is 10000h, the number of samples and stations is 3 each, the power supply is AC 220V, 50Hz, the overall dimension is 600×240×400mm, and the net weight is 20Kg.

The packing list includes 1 set of holding adhesion tester host, 3 weights (complying with pharmacopoeia), 3 test plates (complying with pharmacopoeia), 1 standard pressure roller, 1 copy of certificate and warranty card, 1 copy of instruction manual, and 1 power cord.
