Viscosity of ULTIMA-Flo Cocktails Discussion and Recommendation To help determine the proper pump for use in a laboratory automation project, a researcher contacted our laboratories and requested viscosity data for ULTIMA-Flo™ M (PerkinElmer part number 6013579) and ULTIMA-Flo AP (PerkinElmer part number 6013599) for various ratios with water. Water was added to both ULTIMA-Flo M and ULTIMA-Flo AP at ratios up to 1:1 and the viscosities were measured at 25°C. The results are shown below: N O T E Problem Cocktail No Sample 3:1 With Water 2:1 With Water 1:1 With Water ULTIMA-Flo AP 14 cSt 22 cSt 22 cSt 19 cSt ULTIMA-Flo M 17 cSt 28 cSt 23 cSt 23 cSt In the above table, cSt represents centiStokes and is equivalent to mPa.s (milliPascal seconds).
