You should consider an upgrade if you currently own a vernier model stereotaxic. We can upgrade most major stereotaxic brands. Upgrading your existing stereotaxic to a digital model will reduce the risk of human error and increase accuracy (10-rather than 100-micron resolution). The large LED display is also useful for surgeries performed in low light, or constrained environments where reading the vernier scale is difficult.

Saves Time and Improves Accuracy

Stoelting introduces its latest innovation to our Lab Standard™ Stereotaxic Instruments. We have added a sealed  electronic sensor, highly immune to outside interference and environmental conditions, to each axis of the manipulator arm. Measurements are accurate to 10 microns in all three directions. Movements are now monitored by a large, easy-to-read LED display module, with resolution as precise as 10 microns.



Target coordinates can be programmed into the memory of the 51900 and 51903 Digital Lab Standard™ Stereotaxics.


Zeroing Function for Targeting Specific Coordinates

A zeroing function allows the user to set a reference point for targeting specific coordinates on the animal’s skull for injection, implantation, etc. Calculation of distance measurements via the vernier scales is thus no longer necessary…saving the user valuable time and improving accuracy.

The classic design and high quality of our conventional Lab Standard™ manipulators are exactly the same on the new Digital Stereotaxic, with no drift and smooth movements. The Digital Lab Standard™ keeps the custom triple-start lead screws to allow fast positioning, while maintaining consistently smooth movement. The thin cords from the sensors do not interfere with movements, allowing the arm to move freely and be set at any angle.

The display of each axis can be “ZERO”ed at any location, making operation simple and straightforward. To target a specific location, start at Bregma, and reset all coordinates to zero. Move the manipulator arm to the desired point and lower the electrode, probe, or micropipette into place.

Your Choice of Three Purchasing Options

New Digital Lab Standard™ Stereotaxic Instrument complete with LED Digital Display.

Add new Digital Manipulator Arms and an LED Display to your current Lab Standard™ or similar brand of stereotaxic.

Convert your existing Lab Standard™ (or most other brands) by adding digital sensors to their manipulator arms. LED Display Module included.


Versatility of Positioning

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.



All of the accessories for the Lab Standard™ Small Animal Stereotaxic Instrument fit the 51900 and 51903 Digital Lab Standard™ Small Animal Stereotaxic Instrument. Probe holders and species adapters for "U" frame stereotaxic instruments made by other manufacturers are generally compatible with the Lab Standard frame.

The 51900 and 51903 Digital Lab Standard™ Small Animal Stereotaxic Instruments come complete with a standard probe holder with corner clamp (51631) and a Rat Adapter (51621) with nose holder and 18 degree taper ear bars. The 51950 and 51953 include the non-puncture (45°) ear bars instead of the 18-degree ear bars. They are otherwise identical to the 51900 and 51903.


The time-proven U-Frame design concept, rugged construction, and adaptability to most species used in the lab make Stoelting’s Lab Standard™ series the best choice for stereotaxic instruments.
