B. Conical Fitting with a 6% (Luer) Taper Multipurpose Tester:

Our tester is based on PLC controls and adopts a 5.7-inch color touch screen to show menu. Operators can use touch keys

to choose nominal capacity of syringe or nominal outside diameter of needle as per product specification. Axial force,

torque, hold time, hydraulic pressure and separation force can be displayed during the test.

The tester can test liquid leakage, air leakage, separation force, unscrewing torque, ease of assembly, resistance to

overriding and stress cracking of conical (lock) fittings with a 6% (Luer) taper for syringes, needles and certain other

medical equipment, such as, infusion sets, transfusion sets, infusion needles, tubes, filters for anesthesia, etc. The built-in

printer can print the test report.

Tester Range:

Axial force: 20N~40N; error: within ±0.2% of reading.

Hydraulic pressure: 300kPa~330kPa; error: within ±0.2% of reading.

Torque: 0.02Nm~0.16Nm; error: within ±2.5%.

A.Reference Conical Fittings/Gauges

A Luer fitting is the most common means of achieving a leak-free connection between two medical devices that carry small

volumes of fluids.

There are two types of Luer fittings, Luer slip and Luer lock.

A Luer slip fitting consists of a tapered cone and a mating tapered cavity.

A Luer lock fitting consists of a Luer slip fitting with locking threads added. The Luer lock fitting creates a more secure

connection.

Our Reference Conical Fittings/Gauges are useful for performing the following tests as per ISO 594-1:1986 & ISO 594-2:1998

Ease of Assembly: Ensures that the sample Luer can be assembled with minimum axial force and torque.

Gauging: A dimensional check is performed using a calibrated plug gauge.

Liquid Leakage: Ensures that the sample Luer does not leak when pressurized with water.

Air Leakage: Ensures that the sample Luer does not leak when a vacuum pressure is applied.

Aspiration Leakage: Ensure that the sample luer does not form bubbles when a vacuum pressure is applied.

Separation Force: Ensures that the sample Luer remains attached to the reference fitting when an axial load is applied.

Unscrewing Torque: Ensures that the sample Luer remains attached under a specific unscrewing (counter-clockwise)

torque.

Resistance to Overriding: Ensures that the threads cannot be overridden by a specific screwing (clockwise) torque.

Stress Cracking: Ensures that the sample Luer does not crack when assembled for 48 hours.

Our Reference Conical fittings/Gauges with a 6% (Luer) taper are designed and manufactured according to ISO 594-1:1986 &

ISO 594-2:1998 for testing the Syringes, Luer Hub: Needles, Catheters, Filters, Adaptors, Connectors and certain other medical

equipments including Infusion Set, Transfusion Set & Three Way Stopcock.
