Microbore IV Extension Sets – Low-Volume Tubing for Precision Delivery

Microbore IV extension sets are designed with very small internal volumes to support precise medication delivery and reduce drug waste. By minimizing priming volume between the syringe or pump and the patient, microbore tubing helps achieve faster onset of therapy and more accurate dose adjustments, especially for critical infusions.

This category features microbore extension sets configured for syringe pumps, smart pumps, and standard IV setups. Options include straight extensions, sets with needle-free injection ports, pressure-rated lines, and dedicated microbore tubing for central lines and PICC access.

What You Can Order in This Category

Syringe Pump Microbore Extension Sets — Short, low-volume lines optimized for syringe pumps and high-alert medications.
Microbore Extensions with Needle-Free Ports — Extension sets with swabable valves for intermittent access and safe medication boluses.
Pressure-Rated Microbore Tubing — Lines designed to tolerate higher pressures associated with syringe pumps and certain imaging or contrast protocols.
Microbore PICC/Central Line Extensions — Low-volume tubing configured to connect directly to central venous catheters for precise distal dosing.
Multi-Port Microbore Extensions — Sets with multiple needle-free ports or Y-sites to support several medications through a single access point.

Key Technical Features

Low Priming Volume

Microbore internal diameter significantly reduces priming volume compared with standard-bore extension tubing.
Supports accurate titration and faster response when changing infusion rates or medications.

Lengths & Configurations

Common lengths range from approximately 7 inches to 30 inches or longer, supporting bedside flexibility while keeping dead space low.
Straight or coiled tubing options depending on workflow and space constraints.
Single-port or multi-port configurations with one or more injection sites.

Connections & Safety Features

Rotating male and female luer lock connectors for secure, leak-resistant connections.
Swabable, needle-free valves that support closed-system access and help reduce needlestick injuries.
DEHP-free and latex-free materials available to align with institutional safety standards.

Where Microbore IV Extension Sets Are Used

ICU, CCU, and step-down units — Vasoactive drips, inotropes, insulin infusions, and other titrated medications.
NICU and pediatrics — Patients where even small volume differences can significantly affect dosing accuracy.
Anesthesia and procedural areas — Close control of short-acting agents administered via syringe pumps.
Oncology and infusion centers — Biologics and high-cost therapies where medication conservation is critical.
Home infusion and ambulatory pumps — Compact line management with minimal dead space.
