A Luer connector is a standardized, leak‑free connection system widely used in medical devices to transfer small volumes of fluids. Its reliable sealing performance is achieved through a precision 6% taper design that ensures a secure fit between male and female connectors.

There are two main types of Luer connectors: Luer Slip and Luer Lock.

• Luer Slip Connector – consists of a tapered male cone and a matching female cavity. Connection is made by simply pressing the two parts together, relying on friction for sealing.
• Luer Lock Connector – builds upon the Luer Slip design by adding locking threads, providing a more secure and robust connection that prevents accidental disconnection during use.

What Tests Are Required?

In accordance with international standards, including GB/T 1962.1 and GB/T 1962.2‑2001, the following performance tests are essential to ensure the quality and safety of Luer connectors:

Sumspring Luer Connector Comprehensive Tester

The Sumspring Luer Connector Comprehensive Tester is a state‑of‑the‑art instrument designed to perform all the above tests with exceptional precision and efficiency. Our reference conical fittings and gauges feature a 6% (Luer) taper and are manufactured in accordance with ISO 594‑1:1986 and ISO 594‑2:1998. They are suitable for testing syringes, Luer hubs, needles, catheters, filters, adaptors, connectors, and other medical devices including infusion sets, transfusion sets, and three‑way stopcocks.

Key Features & Advantages

Intelligent Control, Easy Operation
Powered by an advanced PLC control system with a 5.7‑inch color touch screen. Operators can easily select the nominal capacity of syringes or the nominal outside diameter of needles from the menu, significantly reducing the learning curve and minimizing operational errors.

All‑in‑One Testing Capability
The tester fully covers all core test items including liquid leakage, air leakage, separation force, unscrewing torque, ease of assembly, overload resistance, and stress cracking. It is widely applicable to syringes, needles, infusion sets, transfusion sets, catheters, anesthesia filters, and three‑way stopcocks.

Real‑Time Data Visualization & Traceability
During testing, the screen displays real‑time data including axial force, torque, hold time, hydraulic pressure, and separation force. Once testing is complete, the built‑in micro printer produces standardized test reports with one‑key operation, ensuring full data traceability – a critical requirement for quality control in the medical device industry.

The Sumspring Luer Connector Comprehensive Tester combines precision, versatility, and ease of use to help medical device manufacturers meet rigorous international standards and ensure patient safety. Whether you are testing syringes, infusion sets, or complex medical connectors, this instrument delivers the reliable results you need.
