Model 900LS - Small Animal Stereotaxic Instrument: Lazy Susan
Model 900LS (Lazy Susan) Small Animal Stereotaxic Instrument is an adaptation of our Model 900 Small Animal Stereotaxic Instrument. The unique style base plate allows the entire base plate with “U” frame to be rotated through 360°, easily changing its position for the researchers access to the experiment at hand. There is a locking screw that allows the unit to be secured in place.
The instrument consists of a rugged “U” frame to which is affixed a Model 960 three-dimensional Electrode Manipulator. Model 1770 Standard Electrode Holder with corner clamp is included.
Manipulator X,Y, Z adjustment – Metric scale 80 mm travel, calibrated 0.1 mm vernier scale.
