Our rat tail vein cannulae feature a sharp 25ga (0.5mm OD) stainless steel needle with a segment of extension tubing. Insert directly into the tail vein of a restrained rat for manual blood sampling or dosing. Since it is a sharp needle it is not designed to be taped in place for an extended period.
Access the cannula through an included PinPort™ to create a closed, low-dead-volume system that seals shut when the syringe is removed. Click in the product list below for detailed specification sheets.
Having a reliable connection between a surgically implanted catheter and an external device is critical in laboratory animal research. Read this study on reasons for unwanted catheter disconnection.
