Syringe Seal Positive Pressure Tester ISO 7886

The Syringe Seal Positive Pressure Tester is a precision testing instrument designed to evaluate the sealing performance of medical syringes under specified positive pressure conditions. By applying controlled axial pressure and lateral force to simulate actual syringe use, the tester accurately determines whether syringe sealing performance meets relevant quality requirements. The instrument features touch screen operation, automatic timing, real-time parameter display, and built-in printing capability, making it suitable for medical device manufacturers, quality control laboratories, and research institutions.

Application

Syringe seal positive pressure tester is suitable for measuring the closeness of medical syringes. It can accurately determine whether the syringe sealing performance meets the specified requirements.

Syringes are widely used in medicine industry. Its quality is closely related to our health and safety. Syringe positive pressure tester introduces new technology design, 5.7-inch (120 × 90) single-color LCD touch screen display. The nominal capacity of the syringe, lateral force used for leak test and the axial pressure are selected by the keyboard, and lateral force, axial pressure, duration action time on the mandrel are displayed during testing and test result can be printed by the on-board printer.

FAQ

(1) What performance does this tester evaluate for medical syringes?

The instrument evaluates syringe sealing reliability by applying specified axial pressure and lateral force. It helps identify leakage risks caused by poor sealing, assembly defects, or material problems during syringe production and quality verification.

(2) What syringe sizes can be tested with this equipment?

The tester supports syringes with nominal capacities from 1ml to 60ml. Before testing, users should confirm the required fixture configuration and test conditions according to the syringe type and applicable standard requirements.

(3) Why is positive pressure testing important for syringe quality control?

Positive pressure testing simulates pressure conditions that may occur during syringe use. It helps manufacturers verify sealing performance and reduce potential failures caused by leakage, ensuring safer medical device applications.

(4) How can laboratories ensure test result reliability?

Reliable results depend on correct sample installation, suitable test parameters, and regular instrument calibration. The tester is designed with controlled force and pressure systems to reduce operational errors and improve repeatability.

(5) How should a laboratory select a suitable syringe sealing tester?

Selection should consider syringe capacity range, required testing standards, pressure range, data management needs, and production inspection requirements.
