• Absolute lock at 90 degrees (vertical)
• Brass bushings in manipulator arm permit electrical grounding
• Accessories available for use with a wide variety of small animals
• Adaptors available for use with mice, neonatal rats, birds and other species
• Gas anesthesia compatible
• Easily cleaned durable surface
• Warmer ready base compatible with Stoelting Rodent Warmer System

Versatile Positioning
The manipulator arm controls medial-lateral and ventral-dorsal using exclusive triple lead screws for faster positioning, and anterior-posterior movement via dovetail slide movement, with 80mm of travel possible in each direction. A universal joint allows the researcher to change the angle of the probe up to 90° in either the anterior-posterior or mediallateral planes. The improved locking mechanism on the Lab Standard™ will hold any angle position without slipping. And of course, it also provides an absolute lock at 90° vertical.

Easily-Read Scales
All scales are oriented to be easily read from the open end of the ‘U’ — the position from which most scientists prefer to work.

The scale numerals are large, and easy to read. The scale lines are laser engraved, to allow the finest possible permanent marking of scales on all 3 axes. Precise alignment with facing vernier scales gives accurate resolution to 100 microns.

Smooth, Consistent Movements
The Lab Standard’s™ exclusive, triple-lead screws allow smooth consistent movements with the fastest positioning possible.

Included Components

Both 51600 and 51603 include the U-frame Base, Manipulator Arm(s) 51631 Standard Probe Holder(s) with corner clamp and 51621 Rat Adaptor (Nose Clamp Assembly and 18° Taper Ear Bars).

The 51650 and 51653 include Non-Puncture 45° Taper Ear Bars instead of 18° Taper Ear Bars (not shown).

Warmer ready base
Stoelting Stereotaxic Base Plates are designed to be integrated with the Stoelting Rodent Warmer System (sold separately) and are used to maintain body temperature throughout surgical procedures.  Thermal heating pads are embedded into Stoelting stereotaxic base plates to avoid cross contamination with easy clean-up and maintain a sterile environment during stereotaxic surgery. In addition, it can be used as a general warming system or with a rectal thermal probe (sold separately) for homeothermic regulation.

Affordably priced...immediate delivery

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
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.

Smooth Movements
The Lab Standard’s™ exclusive, triple lead screws allow the fastest positioning possible, consistent with lining up the scales easily at a given coordinate.

Versatility of Positioning
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 90^o 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 90^o 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.

Convenient for Electrophysiology
Integral brass bushings in the manipulator arm allow grounding directly to the closest metal on the manipulator arm — even the probe holder.

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.
