Single use of needles

Single-use needles are designed to be used once. If they are reused, there is a risk that they will dull and cause animals pain, as well as potentially transferring tissue products or spreading infection between animals. The UK Home Office adopted single use of needles as a themed inspection area in 2019.

The Precision Injection System, developed through a CRACK IT Challenge encourages the use of new, sterile needles and reduces the time to inject in large cohorts. The technology almost eliminates dead space within syringes, greatly reducing waste, and allows easy needle exchange.

To hear from the Precision Injection System product ambassador, the developers and a Challenge Sponsor, attend our free online webinar: Wednesday 12 October 2022, 14.00 - 15.00 (BST).
