In the pharmaceutical industry, ensuring the integrity of syringe seals is crucial for maintaining accurate drug delivery and patient safety. A Syringe Plunger Seal Integrity Tester is essential in verifying that syringes can withstand the forces applied during use without compromising the plunger stopper’s seal.
Understanding the Syringe Plunger Stopper Test According to ISO 7886-1
The syringe plunger stopper test is designed to check for liquid leakage at the syringe plunger stopper under compression. This test is critical to ensuring that syringes function reliably during medication administration. ISO 7886-1 provides the guidelines for testing syringe integrity, specifically focusing on the plunger stopper’s ability to maintain a proper seal even under pressure.
Test Procedure
The Syringe Plunger Seal Integrity Tester operates by filling the syringe with water and sealing the nozzle. The plunger is then subjected to sideways force to induce the maximum deflection in relation to the barrel. The test applies pressure to determine if any leakage occurs past the plunger stopper seal. This method ensures the syringe can handle the pressure exerted during use without compromising its seal.
How the Syringe Plunger Seal Integrity Tester Works
The SPPT-01 Syringe Positive Pressure Tightness Tester is designed to simulate real-world conditions where pressure is applied to a syringe plunger. The test involves filling the syringe with water to its nominal capacity, sealing the nozzle, and applying a sideways force to the plunger. A force is then applied to the syringe, generating pressure to check for any leakage past the plunger stopper seal. The results help determine the reliability of the syringe under operational conditions.
Key Features of the SPPT-01 Syringe Positive Pressure Tightness Tester
- PLC-controlled operation: The tester features a 7-inch HMI touchscreen for easy operation.
- Precision ball lead screw: This ensures smooth movement and high accuracy during the test.
- Variable test speed: Adjust the test speed between 1~500mm/min as needed.
- Multiple fixture options: The tester is compatible with different syringe sizes and testing needs.
- Overload protection: The device includes safety features to prevent damage during testing.
- Automatic return: After testing, the device automatically returns to its original position for efficiency.
- Microprinter included: The tester generates test reports for accurate record-keeping.
Why Is the Syringe Plunger Seal Integrity Test Important?
The syringe plunger seal integrity test is vital for ensuring that syringes remain leak-proof under compression. A compromised plunger stopper seal can lead to medication leakage, affecting dosage accuracy and patient safety. By conducting these tests, manufacturers guarantee that syringes will function as expected, reducing the risk of contamination, underdosing, or waste.
Ensuring Compliance with ISO 7886-1
ISO 7886-1 Annex D specifies the test method for liquid leakage at syringe plunger stoppers under compression. It ensures that syringes meet the required standards for safety and reliability. Manufacturers in the pharmaceutical industry rely on these guidelines to maintain the highest quality of syringe production. The Syringe Plunger Seal Integrity Tester complies with these standards, making it an essential tool for any quality control process.
