The WPI cannula
system for neuroscience study and pre-clinical research includes an
entire range of cannula options. You are guaranteed:
- Exceptional Quality
- Best Prices
- Rapid Order Response
The three primary components include
the Guide Cannula, the Internal Cannula and the Dummy Cannula (cap).
cannulas are beveled inside and out and then polished to remove any
burrs and ensure that the inside diameter is perfectly cylindrical. This
limits undesired trauma to tissue and ensures smooth operation.
- WPI offers exceptional quality at the best prices.
- Quantities of each item are kept in stock so you can order as needed.
You can see the difference for yourself, when you compare the WPI cannula with the top competitor under a microscope.
The Guide Cannula is a surgical grade, stainless
steel tube that is implanted into a rodent's skull and cemented into
place using dental cement and screws. It guides the Internal Cannula to
the specific injection site.
The Internal Cannula is inserted into the Guide Cannula to sample or inject fluid.
The Dummy Cannula has a stainless steel wire
core, and it is placed in the Guide Cannula when the Internal Cannula is
removed. It seals the opening and prevents tissue from entering the
bottom of the Guide Cannula. The Dummy Cannula is threaded to securely
tighten it so that the animal will not unscrew it while grooming.
Dummy Cannulas are ordered based on the projection length, just like the Internal Cannulas.
Order the Guide Cannulas based on the gauge and
length from the base, and the Internal or Dummy Cannulas based on the
length of the Guide Cannula and the projection from the Guide Cannula

- DUMC–Dummy Cannula
the gauge of the Guide Cannula that will be used, even if you are
specifying an Internal or Dummy Cannula. Choices include 22, 24 and 26
Cannulas can be ordered in a range of lengths from 3.4–8.5mm. Length
can be specified to 0.1mm, with a tolerance of ±0.07mm. For example, a GC24-60 is a 24ga. cannula that is 6.0mm long. For other cannulas, the
length is determined by the desired projection length and the guide
cannula length. The projection can extend beyond the tip of the Guide
Cannula up to 1.0mm.
DUMC Length = GC Length + Projection
INC Length= GC Length + Projection
For example, for an Dummy Cannula flush with the end of a 24ga. Guide Cannula that is 6.0mm long, order an DUMC22-60. For an inernal cannula that projects 0.5mm beyond the 6.0mm Guide Cannula (6.5mm), order an INC22-65.
