SPPT-01 Syringe Positive Pressure Tightness Tester

Product Overview:

The Syringe Positive Pressure Tightness Tester (SPPT-01) is a high-precision instrument designed to ensure the integrity of syringes during their intended use. With a focus on detecting leakage at the syringe plunger stopper under compression, this tester plays a vital role in maintaining drug delivery accuracy and patient safety. Syringe manufacturers and medical device companies rely on this tool to guarantee that syringes meet stringent quality control standards. By testing the syringe’s resistance to leakage under pressure, the Syringe Positive Pressure Tightness Tester helps ensure the effectiveness of syringes in a wide range of medical applications.

Applications:

The Syringe Positive Pressure Tightness Tester is primarily used in laboratories, manufacturing facilities, and quality control environments where syringes are tested for leakage. This device ensures that syringes provide a reliable seal when pressure is applied to the plunger, making it an indispensable tool for industries like pharmaceuticals, healthcare, and medical device manufacturing. The tester is crucial for:

• Medication safety: Preventing leakage that could result in medication loss or contamination.
• Accurate drug delivery: Ensuring the plunger stopper maintains its seal under pressure.
• Quality assurance: Complying with international standards like ISO 7886-1 Annex D.

Working Principle:

The Syringe Positive Pressure Tightness Tester operates by compressing the syringe plunger while the nozzle is sealed. A sideways force is applied to the plunger’s push button, creating a deflection that simulates conditions during actual use. The tester checks for leakage past the plunger stopper as pressure is applied, ensuring that the stopper maintains a tight seal under pressure.

Test Procedure:

1. Preparation: The syringe is filled with water to its nominal capacity and the nozzle is sealed.
2. Deflection Force: A sideways force is applied to the plunger at a right angle to the syringe body, creating a radial deflection about the plunger stopper.
3. Leakage Detection: The tester generates pressure to induce maximum deflection and checks for water leakage past the stopper seal.
4. Analysis: If leakage is detected, it indicates a failure of the stopper seal, which can compromise the syringe's function during use.

Key Features:

• PLC-Controlled Operation: The SPPT-01 is PLC-controlled, ensuring accurate and repeatable tests. It features a 7-inch HMI touchscreen for easy operation and monitoring.
• Precision Ball Lead Screw: This component ensures smooth and precise movements during testing, providing consistent and reliable results.
• Adjustable Test Speed: The tester allows users to adjust the test speed from 1 to 500 mm/min, accommodating different testing needs.
• Multiple Fixtures: Various fixtures are available to test syringes under different conditions, such as downward force tests.
• Overload Protection: Overload protection is built into the device, ensuring the safety and longevity of the tester.
• Automated Test Return: After the test is complete, the tester automatically returns to its starting position, saving time and improving efficiency.
• Microprinter: A built-in microprinter provides real-time printouts of test results for documentation and quality control purposes.
