Research teams working in preclinical models have access to new high-precision measurement tools from Opsens. The systems feature fibre-optic pressure catheters and temperature probes that measure at the very tip of the sensor — a key advantage over conventional units where the transducer sits behind the tip, which may cause offset or slower response.
The product line covers animal-use applications ranging from mice (1 French / 0.33 mm diameter) to rats, rabbits and beyond (2 French / 0.61 mm). The catheters offer many advantages over conventional pressure catheters.
Smart at the tip — true tip-sensing delivers pinpoint accuracy.
Unlike traditional catheters where the sensing element is recessed, Opsens measures directly from the tip. This design delivers instantaneous, high-fidelity data and eliminates pressure lag — giving researchers confidence that their readings reflect the true physiological state in real time. Sampling up to 250 Hz, paired with Opsens’ HandySens M (for pressure) or HandySens G (for temperature), these systems provide unparalleled insight into dynamic biological processes.
No-fuss performer — fibre-optic, metal-free, MRI-safe, and happy in any environment.
Built with Opsens’ proven WLPI fibre-optic technology, these sensors are metal-free and immune to electromagnetic, RF, and microwave interference, making them ideal for MRI environments and other electrically “noisy” setups. Whether it’s cardiac, intracranial, urodynamic or vascular monitoring, Opsens catheters perform flawlessly across a range of physiological applications.
Affordability opens opportunities
Opsens catheters are not only precise but remarkably affordable. By leveraging advanced optical technology and simplified electronics, they free up funds for more experiments or other essential resources. For labs running multiple treatment groups or longitudinal studies, this affordability transforms what’s possible within the same budget.
“These tools are a game-changer for labs working in complex physiological environments, from intracranial to urodynamic to intracardiac monitoring,” said Graham Milliken, CEO of APAC Scientific. “Being able to reliably measure directly from the tip, in EMI-heavy environments like MRI suites, gives our users a major advantage.”
