BASi Research Products will be closed on November 26th and 27th in observance of the Thanksgiving Holiday.

Catheters and Extenders

Catheters Part number Bead Color Dead Volume Description
Long Jugular CX-2010S Yellow 80 µl Use to cannulate the jugular vein. 10-15 cm of catheter will lie outside the exit point, so animals with this catheter must be hooked to BASi Culex ® immediately after implantation. This catheter has only one colored bead anchored below the sleeve for identification. The other anchor bead is clear and adjustable.
Short Jugular CX-2011S Light blue 32 µl Use to cannulate the jugular vein. Only the sleeve of this catheter will lie outside the exit point, so animals with this catheter can be returned to a home cage for recovery. When using this catheter to draw blood, you must use a jugular extender (CX-2031S) to hook the animal to BASi Culex ®.
Short Jugular - Straight Tip CX-2011S-ST Light blue 32 µl Use to cannulate the jugular vein. Only the sleeve of this catheter will lie outside the exit point, so animals with this catheter can be returned to a home cage for recovery. When using this catheter to draw blood, you must use a jugular extender (CX-2031S) to hook the animal to BASi Culex ®.
Long Femoral CX-2020S Green 145 µl Use to cannulate the femoral vein. 10-15 cm of catheter will lie outside the exit point, so animals with this catheter must be hooked to BASi Culex ® immediately after implantation. This catheter has only one colored bead anchored below the sleeve for identification. The other anchor bead is clear and adjustable.
Short Femoral CX-2021S Dark blue 56 µl Use to cannulate the femoral vein. Only the sleeve of this catheter will lie outside the exit point, so animals with this catheter can be returned to a home cage for recovery. You must use a femoral extender (CX-2032S) to hook the animal to BASi Culex ®.
Carotid Catheter CX-2012S Red 25 µl Use to cannulate the carotid artery. Only the sleeve of this catheter will lie outside the exit point, so animals with this catheter can be returned to a home cage for recovery. You must use an extender (use jugular extender CX-2031S, since there are no “carotid” extenders) to hook the animal to BASi Culex ®.
GI catheter CX-8001S White
(may look tan after sterilization)
56 µl Use to cannulate the stomach, duodenum, or peritoneal cavity. This catheter is designed for dosing. Only the sleeve will lie outside the exit point, so animals with this catheter can be returned to a home cage for recovery. No extenders are needed for hooking animals to the Empis dosing accessory.
Bile duct catheter CX-8000S Black 55 µl Use to cannulate the bile duct. Pair this catheter with a GI catheter in the duodenum to recirculate bile when you are not collecting. Only the sleeve of this catheter will lie outside the exit point, so animals can be returned to the home cage for recovery.
Portal Catheter/ Femoral Artery Catheter CX-8002S Orange 55 µl Use to cannulate the portal vein. Alternatively, this catheter can be used to cannulate the femoral artery. Only the sleeve will lie outside the exit point, so animals can be returned to the home cage for recovery. Use a portal extender (CX-2033S) to hook the animal to BASi Culex ®.
Mouse Jugular CX-2022S Light blue 6 µl Use to cannulate the jugular vein of a mouse. Only the sleeve of the catheter will lie outside the exit point. Extenders should not be used to hook the animal to BASi Culex ®.
Mouse Carotid CX-2052S Red 14.5 µl Use to cannulate the carotid artery of a mouse. Only the sleeve of this catheter will lie outside the exit point. Extenders should not be used to hook the animal to BASi Culex ®.
Mouse GI CX-8003S White
(may look tan after sterilization)
8 µl Use to cannulate the stomach or duodenum of a mouse. Only the sleeve will lie outside the exit point. Use this catheter for dosing, either manually or with the Empis accessory.
Extenders Part Number Bead Color Dead Volume Description
Short Jugular Extender CX-2031S Light blue 48 µl Use to hook an animal cannulated with a short jugular catheter to BASi Culex ®. Bead colors will match.
Short Femoral Extender CX-2032S Dark blue 88 µl Use to hook an animal cannulated with a short femoral catheter to BASi Culex ®. Bead colors will match.
G.I. Catheter Extender CX-2029S No bead 186 µl Use to orally dose an animal manually from outside the cage. If you are dosing via Empis rather than manually, do not use an extender. GI extenders have a larger volume than venous catheter extenders, and designed to connect to a luer hub syringe.
Catheter Extender CX-2030S No bead 22 µl Use to dose an animal manually from outside the cage. This can be used with any rat catheter for dosing. If you are dosing via Empis rather than manually, do not use an extender. Do not use to hook an animal to BASi Culex !
Portal Extender CX-2033S Orange 48 µl Use to hook an animal cannulated with a portal vein catheter (either in the portal vein OR in the femoral artery) to BASi Culex ®.  Bead colors will match.
Crossover Extender CX-2034S No bead 140 µl Use to hook an animal cannulated with a peripheral vein catheter when performing first pass metabolism experiments using the BASi Culex ®. This extender will connect the animal with the second BASi Culex ® Controller for blood sampling.
