Standardized Syringe Testing with Zwick


In today's world, the medical industry is continually faced with the challenge of providing patients with better care. Glass syringes that deliver drugs to patients are an essential part of this care. These glass syringes are typically used in connection with injection needles, needless Luer locks, adapters, and transfer devices.

The need for accurate and repeatable tests on syringes is playing an increasingly important role. Standard ISO 11040-4 provides producers of syringes and drugs a shared basis for producing reliable test results.

Zwick testing solutions to ISO 11040-4

ISO 11040-4 (Prefilled syringes -- Part 4: Glass barrels for injectables and sterilized subassembled syringes ready for filling) defines the following tests:

■C1: Flange breaking resistance
■C2: Luer cone breaking resistance
■E: Glide force test method to evaluate syringe lubrication
■F: Needle penetration test
■G1: Needle pull-out force
■G2: Closure system liquid leakage test
■G3: Luer lock adaptor collar pull-off force
■G4: Luer lock adaptor collar torque resistance
■G5: Luer lock rigid tip cap unscrewing torque
■G6: Pull-off force of the tip cap or the needle shield

Zwick is the first materials testing machine manufacturer that offers a complete portfolio that tests to ISO 11040-4. The interchangeable test fixtures are ideal for various syringe types and ensure that the testing of prefilled syringes is standardized.

Running Better Trials Taking an Intelligent Monitoring Approach


When it comes to implementing a risk-based monitoring program, it is not just about reducing monitoring visits and doing less Source Document Verification (SDV). Itís about bringing together your people, a solid process, and the right technology to run a better trial. Success with risk-based monitoring requires the ability to make sense of the thousands, if not millions, of data points captured by multiple disparate sources in a clinical trial. With the sheer volume of data generated on a daily basis comes complexity. How does one make sense of it all? Information overload burdens even the most experienced study teams who struggle to understand which data matters most and what it means.
