Marsh Funnel

The marsh funnel is made of break-resistant plastic and has a fixed orifice with a specified diameter. A fixed mesh near the top across half the cone avoids the orifice from getting blocked by greater particles. The high-impact plastic measuring cup is designed specifically for use with a marsh funnel viscometer and has scales in cubic centimeters and fluid ounces. The marsh funnel viscosity is the ratio of the speed of the sample fluid as it passes through the orifice to the amount of force that is causing the fluid to flow. The marsh funnel viscosity is reported as the number of seconds required for 1000 cm³ of sample fluid to flow out of a full marsh funnel.
