Objectives To determine the properties and quality of the horse joint supplements Legend and Hyalovet by: Using the rheometers to measure the viscosity and elasticity. Finding the intrinsic viscosity using capillary viscometers.

Rheometers Rate ControlStrain Control

Viscometer Glass tubes that can be used to calculate the intrinsic viscosity of polymer solutions by measuring the rate at which a liquid falls through the capillary at different dilutions. Capillary Timing Lines

Hyaluronic Acid Biopolyelectrolyte High molecular weight viscoelastic properties costs 100,000 per kilogram Sources of HA rooster combs micro-organisms umbilical cords

IV = 534 IV = 531 (ml/g) Intrinsic Viscosity = 1074 ml/g IV = 991 ml/g

They Came to Tame the Lame

Conclusions The experiments performed on the rheometer showed similar readings for the flow of Legend and Hyalovet Legend and Hyalovet showed the same viscous and elastic moduli. The intrinsic viscosity of Hyalovet is twice that of Legend which shows that Hyalovet has a larger molecular weight.
