Medical Syringe Positive Pressure Leak Tester

Medical Syringe Positive Pressure Leak Tester is a professional, laboratory-grade pressure mechanics verification system engineered and manufactured by Peyotal to accurately assess the leak-tightness and structural seal secureness of medical syringe barrels. As one of the key methods used to evaluate medical syringes for global manufacturers, independent testing laboratories, and national scientific testing departments, this automated instrument ensures flawless safety audits under positive pressure constraints. 

Standards: Fully compliant with leading international testing and calibration frameworks including ISO 80369, ISO 9626-2016, and ISO 7864-2016.

Q1: What is the primary laboratory testing principle and mechanical workflow for a positive pressure leak test?

A: The testing principle focuses on simulating heavy physical injection forces. The selectable syringe sample (from 1 ml to 60 ml) is filled and securely positioned inside the custom instrument fixture. The automated system applies a regulated lateral force of -88 Kpa +- 0.3 Kpa while simultaneously loading a heavy axial positive pressure from 100 kPa to 400 kPa onto the syringe barrel. The PLC intelligence locks the pressure and executes a strict 30-second test holding window to evaluate if any liquid or air bypass leaks through the barrel walls or connection hub, automatically generating reports via the on-board printer.

Q2: Why does the Peyotal factory combine both lateral force and axial pressure in this single tester?

A: For medical device factories, university research labs, and national science ministries, standard uniform pressure testing is not enough to pass international audit frameworks like ISO 80369. During actual medical injections, healthcare workers always apply uneven hand pressure that creates a bending lateral stress on the luer hub or barrel. By combining a controlled lateral force with high axial pressure, our machine perfectly evaluates structural limits under realistic conditions, ensuring zero false-positive data for your regulatory health audits.

Q3: How does the integrated PLC and 7-inch color LCD display simplify laboratory operation?

A: The tester features an industrial PLC core that fully automates the pressure ramp-up, threshold holding, and timing sequences, keeping the pressure error under approximately 5% and timing error under 1 second. The 7-inch professional color LCD display offers an intuitive menu display in both Chinese and English. Technicians can monitor all parameters in real-time, execute machine calibrations, and print duplicate audit receipts immediately after the test cycle using the built-in printer.

Q4: What are the facility infrastructure requirements to install this positive pressure tester?

A: Peyotal designs its modern medical equipment testing catalog for complete laboratory simplicity and standalone plug-and-play installation. The unit runs entirely on a standard AC 220V grid with an energy-saving 60W machine power draw. Weighing only 10kg with a compact 420 mm * 330 mm * 280 mm footprint, it requires no large external high-pressure fluid pumps for standard operation. The package arrives completely factory-sealed with the main instrument, specialized multi-spec fixtures, printing paper, and a detailed user instruction manual included.
