Syringe Sealing Negative Pressure Tester

The Syringe Sealing Negative Pressure Tester is a precision instrument designed to evaluate the integrity of syringe barrels under negative pressure conditions. It is widely used to ensure the tightness of disposable sterile syringes, infusion sets, blood transfusion sets, catheters, anesthesia kits, filters, and other medical devices, providing essential quality assurance for production and R&D.

Application

This tester is suitable for a wide range of medical device testing, including:

(1) Disposable syringes of various capacities – verifying barrel integrity and piston sealing under negative pressure.

(2) Infusion sets and blood transfusion sets – assessing fluid-tight performance.

(3) Catheters and anesthesia kits – checking connections for leakage prevention.

(4) Medical filters and quick connectors – ensuring negative pressure resistance and sealing.

(5) Production line quality control – ensuring consistent tightness and performance across batches.

(6) Research and development – evaluating new designs and materials for syringe barrels and fittings.

Test Procedures

(1) Install the syringe in the testing fixture, ensuring no pre-tension or deformation.

(2) Set the desired negative pressure and test duration on the interface.

(3) Start the test; the system automatically applies negative pressure and monitors for leaks.

(4) Record the pressure values and duration for evaluation of syringe tightness.

(5) Adjust settings as needed for different syringe types and capacities.

Maintenance Information

(1) Keep the device clean and free of dust and liquids.

(2) Check the pressure sensor regularly for calibration and accuracy.

(3) Store in a stable environment at moderate temperature and humidity.

(4) Follow electrical safety protocols during operation.

(5) Periodically inspect the fixture and control system for wear and replace components as necessary.
