How to Measure Syringeability

SYRINGEABILITY can be considered to be the ability of a product to be successfully administered by a syringe and appropriate needle.

Syringes are used in hospitals, surgeries and homes around the world on a daily basis, and for a multitude of purposes. Successful administration, as well as comfortable receipt of the material under the skin, rely on the effective tracking of the syringe piston within its outer tube. By testing the ease with which an injectable solution is expressed, manufacturers are able to optimise usability and patient comfort, while guaranteeing quality control and product safety.

Manufacturers can also determine the force required to remove the plunger from the syringe, thus emulating the ease with which the syringe piston is withdrawn.

The above are only typical examples of syringeability measurement. We can, of course, design and manufacture probes or fixtures that are bespoke to your sample and its specific measurement.

Once your measurement is performed, our expertise in its graphical interpretation is unparalleled – no-one understands texture analysis like we do. Not only can we develop the most suitable and accurate method for the testing of your sample, but we can prepare analysis procedures that obtain the desired parameters from your curve and drop them into a spreadsheet or report designed around your requirements.
