Product Description
Polyurethane Intravascular Tubing
This is the most commonly used formulation of polyurethane for laboratory animal research. It is the same tubing we use to make our finished catheters. The 2 and 3Fr sizes have been specially extruded to have ideal fits with PinPorts and Vascular Access Harnesses and Buttons: our 2Fr fits 25ga, our 3Fr fits 22ga. The 1Fr size is used in two-piece mouse catheters; the 32ga size is used in intrathecal catheters. Sterilize using EtO. For laboratory research only.

Instech does not sell all sizes of tubing shown here. Follow links above each chart for available sizes and prices. Values are approximate; in particular IDs of extruded tubing typically vary by �0.002in (0.05mm) from nominal values. If dead volume is critical measure the tubing you are using directly by comparing the weights of a filled and empty sample.
