What are the Standard Stereotaxic Instruments?

The RWD Standard Stereotaxic Instruments are the foundational workhorses of neuroscience surgery labs worldwide. Designed with a rigid "U"-shaped frame for maximum stability, these instruments deliver 0.1 mm (100 μm) resolution positioning in all three axes — enabling precise, repeatable targeting of brain structures in rats, mice, and a wide range of other small animals. Whether you are injecting viral vectors, implanting electrodes, or placing cannulae, the Standard Stereotaxic delivers the accuracy and reliability that demanding neuroscience protocols require.

The dual-lead screw mechanism ensures smooth, backlash-free movement, while laser-engraved scales and a unique anti-clockwise UP indicator on every knob eliminate setup errors. Interchangeable adaptors for rats, mice, rabbits, birds, and guinea pigs make this a versatile platform across species, and the extended 400 × 255 mm base plate accommodates a broad range of animal sizes without compromising stability.

Key Features

• 0.1 mm Resolution in All Axes: Working distance of 80 mm per axis with laser-engraved scales for comfortable, accurate reading — suitable for the vast majority of stereotaxic coordinates used in rodent brain atlas targeting.
• Dual-Lead Screw Design: Two parallel lead screws per axis deliver smoother, more stable, and more accurate manipulation compared to single-screw designs, reducing mechanical play and improving repeatability.
• "U"-Shaped Rigid Frame: The robust frame design minimizes flex and vibration transfer, keeping the animal head securely fixed throughout the procedure.
• Unique UP Indicator: An anti-clockwise UP mark engraved directly into every adjustment knob prevents incorrect operation and ensures consistent directionality across operators and sessions.
• Curved Nose Clamp & Ear Bar Plate System: The curved nose clamp securely anchors the animal's head without excessive pressure, while the plate-press ear bar mechanism provides firm fixation with reduced tissue trauma compared to traditional clamping.
• Multi-Species Adaptors: Interchangeable adaptors for rat, mouse, neonatal rat, rabbit, bird, guinea pig, and cat allow a single instrument to serve diverse experimental protocols.
• Full 360°/180° Rotation: The electrode/injection arm rotates 360° horizontally and 180° vertically, locking securely at any angle — enabling angled injection trajectories and complex surgical approaches.
• Extended Base Plate: The 400 × 255 mm base plate provides ample workspace for connecting syringe pumps, heating pads, and monitoring equipment alongside the surgical setup.
