Objectives

This study evaluates the properties and quality of the horse joint supplements Legend and Hyalovet by measuring viscosity, elasticity, and intrinsic viscosity using rheometers and capillary viscometers. The intrinsic viscosity findings indicate differences in molecular weight. Conclusions highlight similarities and distinctions between the two supplements.

Presentation Transcript

  1. 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.

  2. Rheometers Rate Control Strain Control

  3. 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. Timing Lines Capillary

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

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

  6. They Came to Tame the Lame

  7. 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.
