David Kopf Model 962 Dual Ultra Precise Small Animal Stereotaxic Instrument is designed to bring new standards of positioning precisionto the small animal stereotaxic. The instrument consists of a rugged “U” frame manufactured by Kopf Instruments since 1963. The frame is mounted to the 10″ x 14″ base plate and is elevated to bring ear bar height to 50mm. The Model 920 Rat Adaptor (including adaptor plate and Model 957 Rat Ear Bars) is supplied with the instrument. Ear bar slots on the “U” frame have 0.1mm verniers for ease in centering an animal.
Affixed to the “U” frame are two Model 961 Ultra Precise Electrode Manipulators (including Model 1770 Electrode Holders). Very close tolerances are held in production, with all dovetail slides precision ground. This, along with backlash-free drive screws and the sheer mass of the manipulators assures the most accurate placement of electrodes as well as a degree of repeatability impossible to find in any other carrier or manipulator. Screws are rendered backlash-free by use of split spring-loaded nuts. Screws have 1.0mm of travel per revolution. Slides have a metric scale. In addition, a large diameter dial is calibrated into 10 micron increments for ease of settings. Large bearing surfaces coupled with unique clamp arrangements make these the most rigid, versatile and accurate manipulators available.
The vertical and lateral slides of the Model 961 are mounted on a massive universal joint that is calibrated in two planes. This universal joint permits any angular setting. Vertical, lateral and A-P movement on the manipulator is 80mm. The end of lateral slide is machined to accommodate all standard electrode holders.
With appropriate accessories such as the Model 925 Swivel Mount, the Model 962 can be used for cats, squirrel monkeys, spider monkeys, rabbits, rats, weanling rats, mice, guinea pigs, turtles, chickens, pigeons, most small birds, small alligators and frogs. Customized adaptors are also available for other animals.
NOTE: Single Ultra Precise Small Animal Stereotaxic Instrument Model 963 is also available.
OPTIONAL ACCESSORIES
Model 925 Swivel Mount
is needed for cats, rabbits, pigeons, monkeys and other larger animals. It allows the “U” frame to be raised and lowered, rotated 360 degrees and tilted up and down in 10 degree increments. The ear bar center can be raised as high as 12 inches. The unit consists of a 3-1/2″ x 3-1/2″ Base Plate (Model 1210), mounting plug, screw, tee handle, washer, post and allen wrench.
The Model 935 Electrode Angle Calibrator
proves a quick and reliable method for the accurate stereotaxic placement of electrodes at any angle including right and compound angles.
Adapted exclusively for use with the 900 Series Stereotaxics, this unit has a lateral slide and rotating vertical post mounted on a zeroing point.
The lateral slide has a 0.1mm vernier attached to a moveable slide block.
When the block is set at zero, the zeroing point of the slide is at ear bar zero.
Model 943 Ear Bar Adaptor
allows the animal to be positioned outside the stereotaxic frame and locked in place. The animal is then easily positioned into the stereotaxic frame.
The Model 943 Ear Bar Adaptor accepts the rat ear bars only, but can be used with any Model Kopf Stereotaxic Frame.
Model 950 Removable Zero Point
allows you to set electrodes while the animal is in the instrument. The vertical distance of this zero point is 30mm above ear bar zero and can be used with larger animals. Designed exclusively for the 900 Series Stereotaxics.
ELECTRODE HOLDERS & CLAMPING DEVICES
- Model 1770 Standard Electrode Holder with Corner Clamp is provided with each electrode manipulator unless otherwise specified It holdselectrodes from 0.4mm to 1.3mm.
