Uniformity is important in the material you choose for the vital job of viscosity control. To sssiure complete uniformity of Methocel® (Dow methylcellulose), pro­duction r u n s of this superior cellulose p m must pass a standard \ascosity measurement . Solutions of Methocel are subjected to a very exacting measurement by timing the rate of flow through a capillary type of tube in the Ubbeholde Viscosimeter. Range of viscosity is important, too. Mettiocel is available in nine different viscosity types, coverirtg a broad range

Measuring viscosity o f solutions o f Methocel in the Ubbeholde Viscosimeter.

from 10 cps to 7,000 cps, as measured in 2 % aqueous solutions at 20°C. By varying this concentration, an even greater range of viscosities can be obtained. Viscosity control with Methocel has simplified processing and improved many products . Colorless, odorless, iner t and remarkably stable solutions of this gum are also widely used as a stabilizer, th ickener , suspending agent , binder and film former.
