Instech Counter-Balanced Lever Arm

Instech Counter-Balanced Lever Arm

Designed to minimize stress on microdialysis probes, Harvard/Instech’s Counter-Balanced Lever Arm moves with the animal to prevent slack in the tether. Most other lever arms use a mass as the counterbalance; ours uses an adjustable spring, making it lighter and more responsive.

• Minimizes stress on microdialysis probes & animal
• Unimpeded animal movement
