About Falling Ball Viscometer

The Hoppler principle is used to measure the viscosity of Newtonian liquid by measuring the time required for a ball to fall under gravity through a sample-filled tube that is inclined at an angle. The average time of three tests is taken; the result is converted into a viscosity value using a simple formula.

Precision Viscosity Measurement

Engineered for precise determination of liquid viscosity, this viscometer relies on the falling ball principle and visual timing. The instrument accommodates a broad spectrum of viscosity values, thanks to its three stainless steel balls of different sizes and densities, enabling versatile measurements in research, quality control, and industrial applications.

Temperature Control & Easy Maintenance

The device features a thermostatic jacket, supporting precise temperature regulation up to 120C for reliable results. The borosilicate glass tube is removable, streamlining cleaning and sample changes. The instrument's robust, corrosion-resistant enclosure enhances durability, making it ideal for frequent laboratory use.

FAQ's of Falling Ball Viscometer:

Q: How does the Falling Ball Viscometer measure liquid viscosity?

A: The viscometer operates by timing the descent of a stainless steel ball through a transparent Newtonian liquid inside a calibrated borosilicate tube. The measured fall time, combined with the known ball and liquid properties, allows calculation of viscosity.

Q: What liquids can be tested with this viscometer?

A: This viscometer is designed for transparent Newtonian liquids within the viscosity range of 0.5 to 10000 cP, making it suitable for a wide array of laboratory and industrial samples.

Q: When is the thermostatic jacketing used during viscosity measurement?

A: Thermostatic jacketing is used whenever precise temperature control (up to 120C) is required, ensuring viscosity values are not affected by temperature variations during measurement.

Q: Where is the viscometer typically installed or used?

A: It is commonly used in research laboratories, quality assurance departments, and process control settings that require adherence to ASTM D5930 or equivalent standards.

Q: What is the process for cleaning the viscometer tube after use?

A: After measurement, the borosilicate tube can be easily removed from the stand for thorough cleaning, ensuring the elimination of any residue and preparing it for the next sample.

Q: How does the use of different balls affect measurement range and accuracy?

A: Three stainless steel balls of varying diameters and densities enable accurate measurement over a wide viscosity range. Selection of the appropriate ball for a specific sample optimizes sensitivity and precision.

Q: What are the key benefits of manual visual timing in this equipment?

A: Manual visual timing requires no electronic interface, reducing complexity and enhancing reliability. This method allows flexible, intuitive operation and is ideal where electronic connections are not feasible.
