2 Goals and purpose

The Department of Biochemistry and Biophysics wishes to purchase a stereotaxic frame to form part of an in vivo electrophysiology setup.

3 Requirement specification

A stereotaxic frame is required to form part of an in vivo electrophysiology setup.

The stereotaxic instrument must be fully compatible with both rats and mice and has to include a bite bar, gas mask (for gas anaesthesia), two ear bar holders, and two ear bars. If a single set of these components does not allow perfect compatibility between the two species, two sets (one for mice and one for rats) must be provided.

The instrument must allow fine adjustment of the angle of the animal’s head to enable levelling of the animal´s skull.

The instrument must be equipped with two (left and right) 19 mm lateral rail mounts approximately 250 mm in length, and a stereotaxic adapter must be included to permit the mounting of a Luigs and Neumann Junior motorized manipulator (already in place).

This adaptor must allow at least 180 and maximum 360 degrees rotation in the horizontal plane.

Furthermore, to facilitate and increase the horizontal and vertical reach of the manipulator, a compatible displacement adapter must be included.

The instrument must have a footprint no larger than 60x60 cm and be compatible with installation on an antivibration TMC table with M6 mounting holes.

The product and all accessories must be delivered within two months of order placement.
