890A: in-situ Large Animal Apparatus
The 890A Large Animal Test Apparatus and its variants (891A and 892A) enable physiology researchers to test and measure muscle responses in the hind limbs of dogs, sheep, swine and larger animals in-situ or in-vivo.
This apparatus is available in three configurations: isometric (890A and 892A) and isometric/isotonic (891A). The isometric configurations measure force-frequency and muscle fatigue, while isometric/isotonic measures force-frequency, fatigue, eccentric contractions, force-length, force-velocity, work and stiffness.
The apparatus provides accurate limb fixation, an animal footplate, a force sensor and/or motor and linear translators to adjust the footplate position with respect to the animal’s limb. It can be used with either hind limb.
The tri-axis positioner allows easy alignment of the footplate with respect to the animal and fine motor movement to adjust resting length or resting tension. The 890A or 892A apparatus come complete with a torque cell while the 891A is designed for use with a 309C or 310C Dual-Mode muscle lever (purchased separately).
Variants
Large Animal Isometric/Eccentric Footplate Apparatus Variants:
891A Large Animal Footplate Test Apparatus: 309C/310C – Measure force-frequency, fatigue, eccentric contractions, force-length, force-velocity, work and stiffness with the addition of a 309C/310C Dual-Mode muscle lever
892A Swine Isometric Footplate Test Apparatus: Easily test in-vivo muscle tissue mechanics in swine and other large animals
