Based on the long-established SR series, the SR-6M-HT Stereotaxic Instruments are designed specifically for mice and are equipped with various functions to fix the head more firmly. The auxiliary ear bar allows clamping actions to be smoothly manipulated with just one hand, letting the operator fix the external auditory canal and check the fixation firmness with the fingertips. The mouth and nose fixing clamp features a slim, compact design appropriate for the mouth of a small mouse, making it easy to confirm that the teeth are fixed firmly. In addition, the SR-6M-HT Stereotaxic Instruments allow easy back/forward and up/down position adjustment. An AP frame bar is provided, to which many different types of accessories can be attached along with the attached micromanipulator: SMM Series (SMM-100 / SMM-100C / SMM-200 / SMM-200C) or SM-15R/L.

The SR-6M1-HT includes the non-rupture type auxiliary ear bar (EB-6).

The SR-6M-HT and SR-6M1-HT have two AP frame bars, while the SR-5M-HT and SR-5M1-HT have one.
