Stainless Steel Swivels for Tethered Infusion or Sampling of Mice and Rats

Instech single-channel stainless steel swivels are autoclavable and may be reused hundreds of times. Self-adjusting seals — at the heart of every Instech swivel — actually improve with use. All stainless steel models include a universal swivel-to-tether clamp which mates with a range of Instech spring tethers.

The 25ga model has the lowest torque and is recommended for mice, though it is also well-suited to rat studies where low dead volume is important. 22ga is the standard size for rats, and 20ga accommodates higher-volume applications.

FAQ

What is the Instech One Channel Stainless Steel Swivel used for?

The One Channel Stainless Steel Swivel allows continuous tethered infusion or blood sampling in freely moving mice and rats. It rotates with the animal's movement to prevent tether twisting and kinking, maintaining uninterrupted fluid flow throughout the experiment.

How many times can the Instech stainless steel swivel be reused?

The swivel is designed for hundreds of reuses. Its self-adjusting seals improve with use rather than degrading, and the stainless steel body can be autoclaved between experiments for sterile reuse.

Which gauge swivel should be used for mice versus rats?

The 25ga model is recommended for mice due to its lowest torque and minimal dead volume, which reduces stress on the animal and minimizes compound dilution. The 22ga is the standard for rats, and the 20ga is available for higher-volume flow applications.

Is technical support for the One Channel Stainless Steel Swivel available in Israel?

Yes. NBT Ltd distributes Instech products in Israel and provides full local technical support, troubleshooting, and application guidance for tethered infusion and sampling setups.
