(Click to see larger image) A new standard of stereotaxic instrument for chronic experiments on mice.

The SR-9M is specifically designed for chronic experiments on mice. Fixation by the chamber frame permits repeated fixations in the same position in an unanesthetized state. Thereby chronic experiments as well as acute experiments can be smoothly done without causing damage to the animal.
The SR-9M can be used for visual and/or auditory experiments. The head holding device can be removed from the base plate so it can be placed under a microscope. An AP frame bar is provided, to which many different types of accessories can be attached like the micromanipulator SM-15 L/R.

By bonding the chamber frame onto the head of a mouse, repeated fixations in the same position in an unanesthetized state have become possible. Once the chamber frame is fixed on the head, without the need for anesthetization, the mouse can be stereotaxically fixed without using the mouth/nose clamp or ear bars, enabling the SR-9M to be used for visual and/or auditory experiments.

For a version without the stereotaxic micromanupulator SM-15 please visit SR-9M-HT.

This AP frame has an 18.7mm square shape since Narishige's stereotaxic manipulators are tailored for this standard.
