These remarkable swivels feature five low-dead-volume channels and rotational torque as low as that of our one-channel models.

• Three standard configurations
• Five, low dead volume channels for microdialysis
• Proportional control for fine continuous movement
• Minimal stress on animal

There are three standard configurations available; one with all 22 gauge infusion channels and two with a variety of combinations of microdialysis channels (low dead volume and lined to protect neurotransmitters) and standard 22 gauge infusion channels.

The practical limit on the number of lines in a traditional fluid swivel has been two; swivels with three or more channels are typically impossible for a rodent to turn and can have large dead volumes or problems with cross-channel leakage.

To solve these problems the seals were kept tight on the Multi- Channel Swivel and a motor was added to assist the rotation. A controller senses the animal’s movement and drives the swivel core to follow the animal. Unlike switch-based systems, this swivel features a proportional control, allowing fine continuous movement to minimize stress on the animal. The torque felt by the animal is similar to that of an Instech Single Channel Swivel.

The control unit mounts to the vertical portion of the counterbalanced arm and is powered by a 12 VDC adapter. The analog motor drive signal is available as an output for rotational activity monitoring.

The Multi-Channel Swivel is counter balanced to minimize forces on the animal. While the power assist circuitry is responsive enough that a mouse can turn the swivel, use with mice is not recommended due to the negligible weight of the animal relative to the swivel.
