![]() ![]() This correlation may be useful for anticipating the need for repeat plasmapheresis. Serum viscosity and electrophoresis are recommended before and after plasmapheresis in order to correlate viscosity and M-spike with patient symptoms. Hyperviscosity syndrome can also occur in multiple myeloma patients.īecause the ability of a monoclonal protein to cause hyperviscosity is affected by its concentration, molecular weight, and aggregation, sera with concentrations of monoclonal IgM greater than 4 g/dL, IgA greater than 5 g/dL, or IgG greater than 6 g/dL should be tested for hyperviscosity. The most common cause of serum hyperviscosity is the presence of large concentrations of IgM monoclonal proteins, and Waldenstrom macroglobulinemia accounts for 80% to 90% of hyperviscosity cases. Common unit - Poise (P) SI unit - Pascal-Second (Pa·s) Common conversion: 1.0 centipoise (cP) 1. This VST-2000 viscosity tester, under GB265-88, G1814, ASTMD445, IP71 and other standards, adopts advanced SCM for control, large color LCD screen in English, operation tips, high-speed thermal printer, advantages of auto-storage and auto-printing of testing results and uniform temperature of homeothermic bathtub. This is the kind of viscosity reported by our instruments and is very commonly used in fluid analysis. Funduscopic examination reveals dilation of retinal veins and flame shaped retinal hemorrhages. Dynamic viscosity is the measure of a fluid’s internal resistance to shear or motion. Hyperviscosity may be manifested by nasal bleeding, blurred vision, headaches, dizziness, nystagmus, deafness, diplopia, ataxia, paresthesias, or congestive heart failure. Temperature will affect the viscosity of most materials, these estimated numbers are based on measurements at 73☏ / 23☌Ĭlick here to download a pdf of the Viscosity Scale Reference Guide.Viscosity is the property of fluids to resist flow. Please check Technical Bulletins for specific mixed viscosity of products. These are general averages and NOT specifics, not all products fit neatly in this chart. If the mixed viscosity of the casting resin you are using is higher than 7,500 cps, you may want to consider vacuum degassing or pressure casting the resin.ĮVERYDAY CONSUMABLE GOODS IN RELATION TO GENERAL PRODUCT VISCOSITY IN CENTIPOISE (CPS) Water 70☏ / 21☌ This is especially true if the resin has high viscosity and short pot life. Air bubbles may then be reflected in a finished casting. ![]() What does viscosity mean to you when selecting a casting resin? If you are using a casting resin with a high viscosity, there is a chance the casting will entrap air. If the mixed viscosity of the mold rubber you are using is higher than 15,000 cps, you may want to consider vacuum degassing the liquid mold rubber. ![]() What does viscosity mean to you when selecting a mold rubber? If you are using a mold rubber with a high viscosity, there is a chance the rubber will cure with air bubbles that may then be reflected in a finished casting. Viscosity testing is a tool used in the production process of just about every type of food and beverage. ![]() Temperature will affect the viscosity of most materials. The higher the viscosity of a liquid, the thicker it is and the greater the resistance to flow. In layman’s terms, viscosity defines a fluid’s resistance to flow. The present study was realized for measuring viscosities of reference liquids using capillary viscometers and Stabinger viscometer SVM 3001 with viscosity. ![]()
