Five Channel Stainless Steel Swivel

For Rats

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

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 our engineers have kept the seals tight but added a motor 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 our single channel swivel.

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

The 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.

There are three standard configurations with a variety of combinations of microdialysis channels which have low dead volume and are lined to protect neurotransmitters and standard 22ga infusion channels.

Use with MC015/10 microdialysis tubing connectors.
