小動物用脳定位固定装置 MODEL 900

SMALL ANIMAL STEREOTAXIC INSTRUMENT MODEL 900

David Kopf Model 900 Small Animal Stereotaxic Instrument is a versatile, easy-to-use instrument that facilitates proper alignment of small animals for the stereotaxic placement of electrodes, micropipettes and other devices.The instrument consists of a rugged “U” frame to which is affixed a Model 960 Electrode Manipulator (includes a Model 1770 Electrode Holder). The frame is mounted to a 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.

There is 80mm of vertical, lateral and A-P movement on the manipulator and each is controlled by a screw drive. Each plane has a 0.1mm vernier scale, with a fully universal joint calibrated on two planes for access from any angle. Ear bar slots on the “U” frame have 0.1mm verniers for ease in centering an animal.

The Model 900 is unsurpassed for versatility and, with appropriate accessories such as the Model 925 Swivel Mount, it 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: Model 900LS (Lazy Susan type) is also available.

OPTIONAL ACCESSORIES

Model 925 Swivel Mount

dki925

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

dki935

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

dki943

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

dki950

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.
