ZH-BL Small Animal Brain Stereotaxic Apparatus

Product Introduction

The ZH-BL Small Animal Brain Stereotaxic Apparatus is a precision positioning instrument designed for neuroscience, neuroanatomy, neurophysiology, neuropharmacology, and neurosurgery research involving small laboratory animals. Using skull surface landmarks as reference points, it enables three-dimensional positioning of specific brain regions and neural structures.

The apparatus supports procedures such as microinjection, neural stimulation, lesioning, and guided positioning. It can be used in studies involving Parkinson's disease models, epilepsy models, brain tumor models, learning and memory, brain stem cell transplantation, and cerebral ischemia.

With a reading accuracy of 0.1 mm, multidirectional adjustment, lockable rotation, and a wear-resistant U-shaped base, the ZH-BL provides precise and stable positioning for laboratory research. Optional animal adapters and compatibility with accessories such as micro-injection pumps, micro-cameras, and skull drills help accommodate different experimental requirements.

Working Principle

The ZH-BL stereotaxic apparatus uses a three-dimensional coordinate-based positioning method. The operator identifies skull surface landmarks, such as the bregma, as reference points and adjusts the operating arm along the vertical, left-right, and front-rear axes.

The scale system provides position readings, while the adjustable rotation mechanism allows the operating arm to be oriented as required and locked in place. Once the target coordinates are established, compatible instruments can be guided toward the selected neural structure for procedures such as injection, stimulation, or other experimental operations.
