Syringeability Test - Glide Force Test for Syringe

Introduction

The syringeability test plays a crucial role in evaluating the ease and effectiveness with which a formulation can be delivered through a syringe. In pharmaceutical and medical device industries, ensuring that a drug product is both syringeable and injectable is essential for safety, efficacy, and user satisfaction. This article explains the principles, methods, and instrumentation used in syringeability testing, while highlighting the expertise and testing solutions provided by Cell Instruments Co., Ltd.

What Is a Syringeability Test?

The syringeability test assesses a formulation’s ability to pass through a syringe needle under controlled force and flow conditions. This test is essential for prefilled syringes, parenteral drugs, viscous solutions, suspensions, and even cosmetic injectables.

It evaluates factors such as:

Plunger force required to expel the liquid
Flow rate consistency
Clogging or obstruction during delivery
Applicability for different needle gauges

By simulating real-world injection conditions, this test ensures the drug delivery system is functional and safe.

The Role of Syringeability in Syringe Functionality Testing

In syringe functionality testing, the syringeability of a product directly impacts both usability and compliance with international quality standards. Regulatory bodies like the FDA, USP, and ISO emphasize the importance of comprehensive functional testing.

Injectability—often tested alongside syringeability—refers to the patient’s or operator’s perception of injection ease, especially in terms of pain, speed, and control.

Syringeability and injectability testing provide quantitative data that manufacturers use to:

Validate the design and usability of syringes
Optimize drug formulation viscosity and consistency
Comply with pharmaceutical device standards
Reduce product recalls and patient complaints

Standard Methods and Test Parameters

Commonly referenced standards include:

USP <382>: Elastomeric Component Functional Suitability
ISO 7886: Sterile hypodermic syringes for single use
ISO 11040: Prefilled syringes requirements
FDA guidance documents on injectable combination products

Typical parameters measured during the syringe test include:

Break loose force
Glide force
Peak injection force
Average flow rate
Cumulative volume delivered

Advanced syringeability tests may incorporate temperature conditions, needle size variations, and formulation aging effects.

MST-01 Syringe Testing Machine by Cell Instruments

To perform accurate and reproducible syringeability and syringe functionality testing, professional-grade instrumentation is essential.

Cell Instruments’ MST-01 Syringe Testing Machine is specifically designed to meet pharmaceutical standards for:

Precise force-displacement measurement
Programmable injection profiles
Multiple syringe sizes and formats
Full data logging and reporting functions

This device ensures high sensitivity, excellent repeatability, and easy integration into quality control protocols. It is ideal for use in R&D, QA/QC labs, and regulatory compliance testing.

Applications of Syringeability and Injectability Testing

The syringeability test is vital in multiple industries:

Pharmaceuticals: Biologics, vaccines, suspensions, viscous drug products
Medical devices: Prefilled syringes, auto-injectors, needle-free injectors
Cosmetics and aesthetics: Injectable fillers
Veterinary products: Multidose syringes and delivery devices

By ensuring easy injection and consistent flow, companies protect user safety, comply with global standards, and support product approval and commercialization.

Best Practices for Syringeability Testing

To achieve accurate results:

Use calibrated equipment like the MST-01
Ensure consistent environmental conditions (temperature, humidity)
Test multiple samples to evaluate batch-to-batch consistency
Record plunger force, flow rate, and visual observations
Align with regulatory documentation for auditing and submission

Avoid underestimating the test’s importance—failure to perform syringeability and injectability evaluations may delay product approvals or lead to post-market failures.
