Key Benefits
- Aseptic catheter access — PinPort design eliminates needle puncture, reducing contamination risk and septum damage during repeated access
- Research-grade tubing — tight tolerances on ID and OD ensure consistent flow rates and reliable catheter connections
- Universal compatibility — luer-based connectors integrate with standard syringes, pumps, and third-party vascular access equipment
Overview
Instech PinPorts provide quick, aseptic access to indwelling catheters without the need for needle puncture. The patented design uses a blunt pin that displaces a silicone septum, creating a sealed connection that can be opened and closed repeatedly without degradation.
The tubing and connector range includes polyethylene (PE), polyurethane (PU), and co-extruded PE/PVC tubing in research-grade formulations, along with luer stubs, needle-free luer ports, couplers, plugs, 3-way and 4-way connectors. All components are designed for compatibility with Instech catheters, VABs, and tether systems.

Frequently Asked Questions
What is a PinPort and how does it work?
A PinPort is a patented connector that uses a blunt pin to displace a silicone septum, creating an aseptic sealed connection to an indwelling catheter. Unlike needle-punctured septa, the PinPort septum is not damaged by repeated access and maintains a reliable seal.
What tubing material should I use for my catheter lines?
Polyurethane (PU) is recommended for most vascular catheter applications due to its biocompatibility and kink resistance. Polyethylene (PE) is suitable for external fluid lines. Co-extruded PE/PVC combines the benefits of both materials.
Are PinPorts compatible with standard luer syringes?
Yes, PinPort injectors and access pins feature standard luer connections that are compatible with any luer-lock or luer-slip syringe.
Can I sterilise the connectors?
Most Instech connectors can be sterilised by ethylene oxide (EtO). Selected components are autoclavable. Check individual product specifications for sterilisation compatibility.
