The Lab Standard™ Stereotaxic
Instrument, manufactured by Stoelting, is ideal for researchers in need
of a versatile, reliable instrument for stereotaxic procedures with
small animals. Precision alignment when using the Lab Standard™
ensures accurate placement of electrodes, micropipettes, and other devices.
The time-proven ‘U’-Frame design concept, sturdy construction,
and adaptability to most model species make this the best choice for
a stereotaxic instrument.
|
| Stoelting's Lab Standard™ offers several advantages over competing
instruments: |
Easily
Read Scales
|
|
Convenient
for Electrophysiology |
All scales are oriented to be read easily
from the open end of the ‘U’. This is the position from which
most scientists prefer to work. The numerals on the scales are larger,
and therefore more easily read. The scale lines are laser engraved,
to allow finest possible permanent marking of scales on all 3 axes.
Precise alignment with facing vernier scales gives accurate resolution
to 0.1mm.

|
Integral brass bushings in the manipulator
arm allow grounding directly to the closest metal on the manipulator
arm—even the probe holder. |
Smooth
Movements
|
|
Dual
Manipulator Model |
The Lab Standard’s™ exclusive,
triple lead screws allow the fastest positioning possible, consistent
with lining up the scales easily at a given coordinate.
|
|
The 51603 Dual Manipulator Lab Standard™
has 3-dimensional manipulator arms on both sides, the second manipulator
arm being properly reversed as to handedness. Dual manipulators are
very useful in studies in which double injections or simultaneous stimulation
and recording are necessary. |
Versatility
of Positioning
|
|
Included
Components |
The manipulator
arm controls medio-lateral and vertical positioning via lead screws,
and antero-posterior movement via dovetail slide movement, with 80 mm
of travel possible in each direction. A Universal Joint allows the investigator
to change the angle of the probe up to 90o in either the antero-posterior
or medio-lateral planes. The improved locking mechanism on the Lab Standard™
will hold any angle position without slippage. And of course, it also
provides an absolute lock at 90o vertical.
In addition, a swing joint allows the investigator to conveniently swing
the manipulator arm and probe out of the way for performing a procedure
– then reliably return the probe to the same point.

|
Both the 51600 and 51603 include
the U-frame base plate, manipulator arm(s), standard probe holder(s)
with corner clamp, and Rat Adaptor (nose clamp assembly and 18°
taper ear bars). The 51650 and 51653 include non-puncture 45° ear
bars instead of 18° ear bars.
|
| Selection
of Accessories |
| Species adaptors
are available to fit rat, cat/monkey, dog/monkey, mouse, guinea pig
and small bird. Probe holders and species adaptors for ‘U’
frame stereotaxic instruments from other manufacturers are generally
compatible with the Lab Standard™ frame. |
