Abstract
New viscometer based on tube viscometey was developed by using micropores of a polyvinyl alcohol (PVA) hollow fiber for plasma separates. After debubbling by alcohol infusion, blind-ended PVA fiber (ID: 200 micron, pore size: 0.2 micron) was infused at varing rates of constant flow of water which viscosity is known at the temperature. When water was oozed through micropores, the pressure (P)-flow (F) relationships showed good linearity. The coefficient (B) of the regression line (P=A+BF) at the known viscosity (V) decided a constant (K) characteristic of the tube resistance. The viscosities (V) of glucose solutions (5, 10, 20, 50%) obtained by this method (V=B/K) were equal to those measured simultaneously by a cone-plate viscometer.
