Key Words:  Air Interface, Evaporation, Glycerol

VROC is a closed system

  • No air interface
  • Air can impact your viscosity values providing readings that may not be quite accurate

Over 18 hours of testing

  • Only a 1.06% difference in viscosity was observed
  • Repeatable, 0.191% RSD
  • Multiple vials were used during this test

VROC initium 

  • Dual temperature control
Holding tray can be set independently to hold samples at 4 °C to further dampen any possible evaporation

Viscosity of 84% Glycerol over Time
