Luer conical joint multi-function tester

The Luer Conical Joint Multi-Function Tester is a precision instrument designed to evaluate multiple performance characteristics of Luer-type connections used in medical devices. It tests leakage, gas tightness, separation force, unscrewing torque, assembly ease, slip resistance, and stress cracking of syringes, needles, infusion sets, catheters, and anesthesia filters. The device ensures reliable performance, safety, and compliance of medical Luer connections for both locked and non-locked designs.

Application

This tester is suitable for a broad range of medical Luer connection testing scenarios, including:

(1) Syringes (1 mL – 60 mL) – verifying leakage, torque, and assembly performance.

(2) Injection needles – testing connection integrity and unscrewing torque.

(3) Infusion sets and blood transfusion sets – assessing slip resistance and stress cracking under load.

(4) Catheters – evaluating connection reliability and sealing performance.

(5) Anesthesia filters – ensuring secure connections and prevention of leaks.

(6) Research and development of new Luer-type connectors – optimizing design for clinical use.

(7) Production line quality control – guaranteeing consistent performance across batches.
