Medical Syringe Air Leakage Tester

Medical Syringe Air Leakage Tester is a professional, laboratory-grade negative pressure testing system designed and manufactured by Peyotal to accurately verify the tightness and seal integrity of medical syringe bodies. As a critical quality control instrument for syringe manufacturing factories, global laboratory networks, and scientific departments, this automated system delivers exceptional pressure stability to ensure full compliance with strict global standards.  

Standards: Fully compliant with international and national calibration frameworks including ISO 7886-1, ISO 8537-2016, and YY0497-2018.

Q1: What is the exact step-by-step laboratory testing principle and workflow for running a syringe leakage test?

A: The workflow strictly follows global quality control standards. First, draw water into the syringe to a volume of not less than 25% of its nominal capacity, keeping the tapered end facing upwards. Retract the plunger until the reference line aligns perfectly with the nominal capacity line, and place the syringe securely into the instrument’s holder. Securely attach the vacuum tube from the tester’s output to the tapered end of the syringe. Turn on the machine, wait for the vacuum pressure display to stabilize, and press start. The PLC system will automatically draw air until the negative pressure display reaches exactly 88 kPa, where it stops drawing and initiates a 60-second holding period. The technician then visually inspects the outer sleeve and piston contact area to ensure no bubbles form (negative pressure change must not exceed the original reading by more than 0.5 kPa) and verifies that the piston does not separate from the core rod.

Q2: Why does Peyotal utilize a PLC (Programmable Logic Controller) system instead of a basic circuit board?

A: For medical device factories, educational institutes, and national science ministries, testing repeatability and long-term hardware reliability under continuous shift work are critical. Peyotal integrates an industrial PLC system to drive the automation. This ensures that the vacuum pull rate, threshold cutoff at -88 kPa, and timing accuracy (error <= 0.1s) remain perfectly accurate across thousands of test runs. It eliminates human operator errors and manual drift, ensuring data consistency for strict regulatory health audits.

Q3: Can the testing pressure and vacuum timelines be adjusted for non-standard medical syringes?

A: Yes, absolutely. While the standard baseline is programmed for -88 kPa to meet ISO 7886-1 requirements, the system provides excellent testing flexibility. Operators can use the 7-inch touch panel to adjust the test vacuum range anywhere from -5 kPa to -90 kPa and set the holding timer from 1 second up to 9999 seconds arbitrarily to suit your laboratory’s unique research or proprietary QA benchmarks.

Q4: Is the installation process complex for remote laboratory facilities in developing regions?

A: Peyotal designs its modern medical testing catalog for absolute simplicity and true plug-and-play installation. The PYT-Syringe Leak Series operates completely on a standard single-phase AC 220V power outlet with an energy-efficient 60W power draw. Weighing only 8.5kg with a compact footprint, it fits perfectly on any clean laboratory workbench without needing external high-pressure gas inputs. The unit arrives ready-to-use with the main instrument, the specialized fixture, printing paper, and the instruction manual enclosed.
