title: VISCOSITIES OF CONCENTRATED NaCl-H2O AND Me2SO-NaCl-H2O SOLUTIONS AT SUBZERO TEMPERATURES.
abstract: BACKGROUND
  Viscosity is an important property of cryoprotectant solutions because it directly influences diffusion and reaction at liquid state.
  
  
  OBJECTIVE
  To measure the viscosities of concentrated NaCl-H(2)O and Me(2)SO-NaCl-H(2)O solutions at subzero temperatures down to -50 degree C.
  
  
  METHODS
  Solution viscosity was measured with a rotary viscometer coupled with a thermostat bath. Two viscosity models, Laliberté model and Williams-Landel-Ferry (WLF) model, were employed in the correlation and prediction.
  
  
  CONCLUSIONS
  The Laliberte model performed well to correlate the viscosities of NaCl- H(2)O solutions measured here and the viscosities of Me(2)SO-H(2)O solutions found in the literature. The parameters obtained were used to predict the viscosities of Me(2)SO-NaCl-H(2)O solutions. The average discrepancy between the calculation and the experimental data was 19.0%. With the WLF model, the average discrepancy between the calculation and the experimental data for ternary solution was 5.4%.
