Ordering
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 tip.

GaugeChoose 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 gauge.
LengthGuide Cannulas can be ordered in
a range of lengths from 3.48.5mm. 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 DUMC24-60. For an
inernal cannula that projects 0.5mm beyond
the 6.0mm Guide Cannula (6.5mm), order an
INC24-65..
Neuroscience Cannulas
For in vivo investigation of rodents
This cannula system for neuroscience study and
pre-clinical research includes an entire range of
cannula options. The three primary components
include the Guide Cannula, the Internal Cannula
and the Dummy Cannula (cap)
WPI 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.
Dummy Cannula
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.

* DUMC Length=GC Lenth + Projection. If the cap is screwed on too tightly, the projection will be longer than expected.
** INC Length=GC Lenth + Projection. Internal cannula mounts flush and does not screw into place.
Guide Cannulas
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.
Internal Cannula
The Internal Cannula is inserted into the Guide
Cannula to sample or inject fluid.
