I. Model 68019 Stereotaxic Instrument, Suitable for Mice and Rats

1. Parameters

l The moving distance can reach 80mm, and the reading accuracy is 0.1mm.

l Double - lead screw design for smoother and more precise operation.

l Wide Y - axis operation interval with a spacing of 28mm.

l The vertical locking and positioning knobs are separated to ensure an absolute 90° verticality.

l Optional adapters for different animals such as rats, mice, small birds, cats, etc.

l Arc - shaped design to avoid hurting the nasal bridge and fix the head more firmly. It can be locked at any position in the vertical direction of 180° and the horizontal direction of 360°.

l The ear bar is locked by a pressure plate, which does not damage the ear bar and provides a more secure fixation. The tip of the ear bar is 51mm away from the base plate.

l The distance between the U - shaped base is 115mm.

l The lengthened base plate is 400mm×255mm, suitable for a variety of animals.

l Digital displacement display for higher accuracy and efficiency!

l Precise displacement sensor, with the reading accuracy increased to 10μm.

l LCD digital display screen to show the displacement distance in real - time.

l Compatible with inhalation anesthesia masks or anesthesia adapters, allowing for safer inhalation anesthesia.

l One - key zero - setting, eliminating the need for secondary reading and calculation.

l Powered by AA batteries to avoid electrophysiological electronic interference.

2.Main Functions

The stereotaxic instrument is an important research device in fields such as neuroanatomy, neurophysiology, neuropharmacology, and neurosurgery. It uses the landmarks on the skull surface (such as the bregma point) as the basic reference point. By moving the three - dimensional manipulator, the position of a certain nerve structure (nucleus) under the animal's cerebral cortex can be determined, and then operations such as directional injection, stimulation, destruction, and guiding positioning on the nerve structure can be completed. It can be used in the establishment of animal models for Parkinson's disease, epilepsy, intracerebral tumors, learning and memory research, intracerebral neural stem cell transplantation, cerebral ischemia research, etc.

3. Operation Range

l Manipulator moving range: It can reach 80mm in the up - down, left - right, and front - back directions.

l Reading accuracy: 0.1mm.

l Rotation angle: It can be rotated 180 degrees in the vertical direction and locked at any position at any time, and rotated 360 degrees in the horizontal direction and locked at any position at any time.

l Base plate size: The lengthened base plate is 400mm×255mm.

l Lateral rotation operation space: The distance between the knob and the U - shaped seat is 28mm.

Ⅱ. Model 68916 Large - Animal Stereotaxic Instrument, Suitable for Large Animals such as Cats, Dogs, Pigs, and Monkeys

1. Parameters

l The uniquely designed adapter upper jaw plate is convenient for fixing the heads of large animals with different weights.

l Optional different adapters for dogs, monkeys, pigs, and other large animals.

l The Y - axis is designed with a slide - rail, and the moving range is longer, ±100mm, with an accuracy of 1mm.

l An optional AP micro - thruster (68104) can increase the Y - axis reading accuracy to 50μm.

l It can accommodate six manipulators for multiple independent operations.

2. Main Functions

The RWD large - animal stereotaxic instrument is an important research device in fields such as neuroanatomy, neurophysiology, neuropharmacology, and neurosurgery. It can be used for directional injection, stimulation, destruction, guiding potential, and other operations on large - animal nerve structures, as well as for establishing animal models such as Parkinson's disease and conducting intracerebral neural stem cell transplantation research.

3. Operation Range

l Reading accuracy: The reading accuracy of the moving distance can reach 0.01mm (digital display type), which can meet the requirements of relatively precise experimental positioning.

l Three - dimensional propulsion stroke: The adjustment range of the three - dimensional manipulator in the X, Y, and Z - axis directions is usually 0 - 80mm, that is, the three - dimensional propulsion stroke is 80mm.

l Angle adjustment: It can be rotated 180 degrees in the vertical direction and locked at any position within this range, and rotated 360 degrees in the horizontal direction and locked at any position within the range.

l Counting accuracy: ±0.01mm, and the accuracy of the three - dimensional thruster is also ±0.01mm to ensure positioning accuracy.

l Working power supply: Generally 1.5V.

l Working conditions: The suitable working temperature is 0 - +40°C, and the relative humidity needs to be less than 80%.

l Storage and transportation temperature: - 10 - +60°C.

l Material and dimensions: Mostly made of alloy materials, with dimensions of approximately 350×250×340mm, and the total weight of the machine is about 5.5kg.
