Fluid Swivels for Continuous Animal Infusion

The swivel, a device that rotates to keep the catheter from tangling, is a critical part of any continuous animal infusion system. The Instech fluid swivel has been in laboratory use for over 35 years and has earned a reputation as the finest in the industry.

All of Instech's swivels are precision machined to ensure ease of rotation, durability and reliability. The design minimizes internal dead volume and eliminates stagnant regions along the fluid path. Fluids passing through the swivel touch only stainless steel hypodermic tubing and Teflon. Special self-adjusting seals, at the heart of every Instech swivel, actually improve with use.

Swivels are available in a variety of sizes for use with a wide range of species -- rodents to large animals. They work with any of Instech's button, harness and head block tethers. For optimal performance they should be firmly fixed outside the animal's cage with one of Instech's swivel/cage mounts. Swivels are also available as part of custom, pre-assembled infusion kits.

The newest addition to Instech's swivel line is the remarkable, power-assisted five channel swivel.
