High Accuracy and Consistency

With a measuring range of 3020,000 mPas and a resolution of 0.01 mPas, the Falling Ball Viscometer guarantees reliable and repeatable viscosity readings. The three included stainless steel balls are calibrated to ensure consistent performance across different sample viscosities. This robust accuracy makes the device ideal for laboratory quality control and research applications.

User-Friendly and Durable Design

Being completely manual and bench-top mounted, the viscometer operates without power supply, making it both simple and versatile. Crafted from borosilicate glass with a chemical resistant finish, the equipment withstands frequent laboratory use and aggressive solvents. Accessories such as a thermometer, cleaning brushes, and a clear instruction manual further enhance its value.

Versatile Temperature and Application Range

Compatible with constant temperature baths, the viscometer enables precise viscosity determination under various thermal conditions (0100C with external bath). Its flexibility is well-suited for research, quality control labs, and industrial applications seeking consistent results under a range of environments.

FAQs of Falling Ball Viscometer:

Q: How does the Falling Ball Viscometer measure viscosity?

A: The device determines viscosity by timing how long it takes a calibrated stainless steel ball to fall through a liquid sample inside a borosilicate glass tube. The viscosity is calculated based on the fall time, ball density, and tube dimensions.

Q: What is the procedure for preparing and measuring samples?

A: Fill the borosilicate glass tube with approximately 4050 ml of your liquid sample, introduce one of the provided stainless steel balls, and, if precise temperature control is necessary, connect the tube to a constant temperature bath. Use the external timer to measure the balls passage between the tubes markings; refer to the manual for calculation details.

Q: When should I use an external temperature bath with the viscometer?

A: Employ an external temperature bath when viscosity readings at specific temperatures are required or when ambient conditions may not be stable. This is especially important for samples whose viscosity changes significantly with temperature.

Q: Where can the Falling Ball Viscometer be set up?

A: As a bench-top device, the viscometer is suitable for laboratories, research facilities, or quality control departments. Its manual design means it does not need electrical power, providing flexibility in placement and use.

Q: What benefits does using borosilicate glass offer?

A: Borosilicate glass ensures excellent chemical and thermal resistance, making the tube durable for repeated cleaning and exposure to various laboratory liquids. This enhances longevity and measurement accuracy.

Q: How do I maintain and clean the viscometer?

A: After each use, clean the tube and stainless steel balls using the provided brushes and follow the cleaning procedures in the instruction manual. Proper maintenance prevents sample contamination and preserves the units accuracy.
