Smooth Movements
The Lab Standard’s custom, triple-start lead screws allow the fastest positioning possible consistent with lining up the scales easily for a given position.

The universal joint allows the investigator to angle the probe in either the anterior-posterior or the lateral-medial planes. The improved locking mechanism on the Lab Standard Stereotaxic Instruments will hold any angled position without slippage. Of course, it also provides an absolute lock at the vertical position. The manipulator arm may be swiveled out of the way for convenience in installing the animal or performing a procedure, then returned to the same point reliably with the aid of the locking face block above the swivel joint.

Easy-to-Read Scales
All scales are oriented to be read most easily from the open end of the “U”. This is the position from which most operators prefer to work. The numerals on the scales are larger and therefore more readable than on competing units. The scale lines are very finely drawn to allow precise alignment with facing scales, and are laser engraved for reliable, consistent quality.

Species
These Stereotaxic Frame Systems are supplied with the necessary components to work with rats. In order to work with other species the appropriate adaptor must be purchased separately. see pages L37 and L38 for species adaptors.

Single and Dual Manipulator Models
The time-proven U-Frame design concept, rugged construction, and adaptability to most species used in the lab make this the best choice for a stereotaxic instrument. The Lab Standard 51600, manufactured by Stoelting, offers several advantages over other U-Frame stereotaxic instruments.

Dual Manipulator Model
The 51603 and 51653 Dual Manipulator Lab Standard are configured with 3-dimensional manipulator arms on both sides. The second manipulator arm is properly reversed as to handedness.

Accessories
Both the 51600 and 51603 come complete with a standard probe holder with corner clamp (51631) and a Rat Adaptor (51621) with nose holder and 18 degree taper ear bars. The 51650 and 51653 include the non-puncture 45 degree ear bars instead of the 18 degree ear bars. They are otherwise identical to the 51600 and 51603.

Optional accessories are available. Probe holders and species adaptors for “U” frame stereotaxic instruments made by other manufacturers are generally compatible with the Lab Standard frame.
