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 good for rat studies where low dead volume is important. 22ga is the standard for rats.
