The RANDHAWA GLOBAL Borosilicate Glass 3.3 Ostwald Viscometer RG-93301 is a precision instrument used for measuring the viscosity of fluids. Constructed from high-quality borosilicate glass, this viscometer is designed to provide accurate and reliable measurements in laboratory settings. The Ostwald viscometer operates on the principle of measuring the time it takes for a fixed volume of fluid to flow through a narrow capillary tube under the force of gravity. By observing the flow time and knowing the dimensions of the viscometer, the viscosity of the fluid can be determined using established formulas. With its borosilicate glass construction, this viscometer offers excellent transparency, allowing for easy observation of fluid flow. The high-quality glass material also ensures resistance to chemical corrosion and thermal shock, making the viscometer suitable for use with a wide range of fluids and under various temperature conditions. The RANDHAWA GLOBAL Borosilicate Glass 3.3 Ostwald Viscometer RG-93301 is commonly used in research laboratories, industrial facilities, and educational institutions for viscosity measurements in fluids such as oils, polymers, and solutions. Its precision design and reliable performance make it an essential tool for scientists, engineers, and researchers involved in fluid dynamics and rheological studies.

RANDHAWA GLOBAL Borosilicate Glass 3.3 Ostwald Viscometer, RG - 22098 is a laboratory instrument used to measure the viscosity of liquids. Viscosity is a property that describes a fluid's resistance to flow, and it is crucial in various scientific and industrial applications, including the food industry, pharmaceuticals, and chemical engineering. The Ostwald viscometer operates on the principle of measuring the time it takes for a liquid to flow through a narrow capillary tube under the influence of gravity.
Key components and principles of the Ostwald viscometer:
U-Shaped Tube: The core of an Ostwald viscometer consists of a U-shaped glass tube, which is open at both ends. One arm of the U-tube is wider and serves as a reservoir for the liquid being tested, while the other arm is a narrow capillary tube through which the liquid flows.
Timing Marks: The capillary tube has timing marks etched or marked along its length. These marks provide a reference for measuring the time it takes for the liquid to travel a specific distance in the capillary.
Temperature Control: Accurate viscosity measurements are temperature-sensitive. Many Ostwald viscometers have a temperature control jacket or a water bath to maintain a constant and precisely controlled temperature during the test.
The procedure for using an Ostwald viscometer is as follows:
The viscometer is filled with the liquid to be tested, which is drawn up into the wider arm of the U-tube.
A stopwatch is started as soon as the liquid reaches a specific reference mark on the timing scale.
The liquid flows under the influence of gravity through the narrow capillary tube, and the stopwatch is stopped when it reaches another reference mark.
The time it took for the liquid to travel the known distance in the capillary tube is recorded.
The viscosity of the liquid is calculated using the specific formula associated with the particular viscometer design and the measured time.
The viscosity measurement is often expressed in units such as poise (P) or centipoise (cP), depending on the system of units used.
The Ostwald viscometer is widely used for routine viscosity measurements of liquids with Newtonian behavior, where viscosity remains constant regardless of the applied shear stress. However, it may not be suitable for non-Newtonian fluids, which exhibit varying viscosity under different shear conditions. For such fluids, specialized viscometers like rotational viscometers or rheometers are preferred. Despite its limitations, the Ostwald viscometer remains a valuable tool for quick and relatively simple viscosity determinations in many laboratory settings.
