Syringes Plunger Glide Force Tester measures the force required to move the syringe plunger, ensuring compliance with industry standards such as ISO 7886-1 Annex E.
Syringes Plunger Glide Force Testing
Syringes play a critical role in medical applications, ensuring safe and precise drug delivery. The smooth operation of the plunger is essential for accurate dosing and user comfort. The Syringes Plunger Glide Force Tester measures the force required to move the syringe plunger, ensuring compliance with industry standards such as ISO 7886-1. This test guarantees that syringes function reliably, reducing risks associated with excessive force or resistance.
ISO 7886-1 - Syringe Glide Force Testing Standard
The ISO 7886-1 standard specifies the test method for determining the forces required to operate a syringe plunger. It ensures consistency in manufacturing and performance, helping medical device manufacturers meet stringent quality control requirements. The test involves:
Using a mechanical testing machine to measure the force needed to move the plunger.
Expelling water from the syringe while recording the force.
Ensuring precise testing conditions, such as controlled water temperature and constant linear displacement.
How Syringes Plunger Glide Force Tester Works
The SSR-01 Syringes Plunger Glide Force Tester from Cell Instruments is designed to provide high-precision measurements of plunger glide force. The device operates by expelling water from a syringe at a constant linear rate while simultaneously recording the force required to move the piston. The testing process follows these steps:
- Preparation: The syringe is filled with water at a controlled temperature (23±5°C) and mounted in the test fixture.
- Plunger Activation: The plunger is moved at a constant rate of 100±5 mm/min using a mechanical testing machine.
- Force Measurement: The force required to initiate and sustain plunger movement is recorded.
- Result Calculation: The tester calculates key values, including:
- Initial force (Fs): Force required to start plunger movement.
- Mean force (F): Average force throughout plunger travel.
- Maximum force (Fmax): Peak force observed during the test.
