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.
