Product Introduction 
The holding tack tester operates on the vertical suspension loading principle. A test plate with the specimen attached is fixed vertically on the test rack, and a specified weight is suspended from the lower end. Under constant load, the specimen's displacement or complete detachment time is observed. The instrument uses a single-chip microcomputer timing system, with an LCD displaying the test time in real time. It mainly consists of a timing mechanism, test plate, loading plate, weights, frame, and standard pressure roller. The standard pressure roller is used for specimen preparation to ensure uniform adhesion between the specimen and the test plate. The weights provide constant load. Three work stations allow simultaneous testing of multiple specimens, improving detection efficiency. The instrument is suitable for holding tack determination of plasters, patches, and medical adhesive products, providing standardized data for product quality evaluation and process optimization.

Key Features
Pharmacopoeia Standard Compliance Designed and manufactured according to the 2015 Chinese Pharmacopoeia Adhesion Testing Method, suitable for plasters, patches, and medical adhesive products.
Single-Chip Microcomputer Timing Uses a single-chip microcomputer timing system with LCD display, timing range 0-100h, ensuring accurate and reliable data.
Three Work Stations for High Efficiency Equipped with 3 test stations for simultaneous testing of multiple specimens, improving detection efficiency for batch quality inspection.

Main Technical Specifications

FAQ
1. What products is the Holding Tack Tester suitable for?
It is suitable for plasters, patches, medical adhesive products, and other pressure-sensitive adhesive products such as tapes, labels, and protective films.
2. What is the principle of holding tack testing?
A test plate with the specimen attached is hung vertically, and a specified weight is suspended from the lower end. The displacement after a certain time or the complete detachment time characterizes the adhesive's resistance to pull-off.
3. What is the timing range and display method?
The timing range is 0-100h, using single-chip microcomputer timing with LCD display for clear and accurate readings.
4. How many work stations does the instrument have?
The standard configuration has 3 work stations, allowing simultaneous testing of multiple specimens for improved efficiency.

5. What are the functions of the standard pressure roller and weight?
The standard pressure roller is used for specimen preparation to ensure uniform adhesion between the specimen and test plate. The weight provides constant load to simulate actual stress conditions.
6. Does the instrument require regular calibration?
Periodic verification of the timing system and weight mass is recommended to ensure test conditions meet standard requirements. Keep the equipment clean and avoid contamination of the test plate surface.
