Viscosity Apparatus by Stoke's Method with Digital Timer & Photo Gate
Model Number: MT-E827A
The Viscosity Apparatus by Stoke's Method with Digital Timer & Photo Gate is a precision laboratory instrument designed to accurately determine the coefficient of viscosity of glycerine, castor oil, and other viscous liquids. Manufactured by Micro Technologies, it combines a traditional Stoke's Method setup with a digital timer and dual photo gate system for highly accurate and repeatable measurements.
Product Specification
The Viscosity Apparatus by Stoke's Method with Digital Timer & Photo Gate is an advanced laboratory instrument developed for precise determination of the coefficient of viscosity of glycerine, castor oil, and similar viscous liquids using Stoke's Law. Manufactured by Micro Technologies, this upgraded apparatus eliminates manual timing errors by incorporating an electronic timing system with optical photo gate sensors.
The apparatus consists of a precision graduated transparent glass tube mounted vertically on a heavy-duty support stand. The transparent observation column enables clear monitoring of the falling steel sphere while maintaining accurate alignment throughout the experiment.
The principle of operation is based on Stoke's Law, where a steel ball falling through a viscous liquid attains terminal velocity. By accurately measuring the time taken by the sphere to travel between two fixed points, the coefficient of viscosity of the liquid can be determined with high precision.
Unlike conventional manual setups, this model is equipped with a Digital Timer and two Photo Gate Units that automatically detect the movement of the falling sphere. The timer starts when the ball crosses the upper photo gate and stops when it passes the lower photo gate, eliminating human reaction time errors and significantly improving experimental accuracy.
The apparatus includes steel balls of different diameters for multiple experimental observations. A 20 × 1 mm screw gauge is supplied for accurate measurement of ball diameter. The kit also includes a glass funnel, experimental liquid (glycerine), measuring tape, and colour-coded rubber bands for marking reference positions.
A dedicated photo gate holding arrangement ensures precise positioning and alignment of both sensors on the observation tube. The rigid laboratory stand provides excellent stability, reducing vibration and maintaining measurement accuracy throughout repeated experiments.
The digital timing system offers fast response, accurate electronic measurement, and easy-to-read digital display, making the apparatus ideal for engineering colleges, universities, research laboratories, physics laboratories, and advanced educational institutions.
Every Viscosity Apparatus by Stoke's Method with Digital Timer manufactured by Micro Technologies undergoes stringent quality inspection and calibration to ensure dependable performance, accurate timing, and long operational life.
