Vacuum capillary viscometer

A vacuum capillary viscometer is a useful instrument to determine the thickness or Runniness of a liquid. Scientists and engineers can use it to learn about the flow character of diverse fluids. It’s especially handy for fields that use oil and food and chemicals. The viscometer operates by running a thin tube, called a capillary, through a vacuum. When this tube is filled with liquid it runs through the capillary. By timing how long it takes for the liquid to travel a set distance, we can learn how viscous, or sticky, the liquid is. Zonwon manufactures quality Vacuum Capillary Viscometers that are reliable and simple to operate.

How to Properly Maintain Your Vacuum Capillary Viscometer for Longevity

A vacuum capillary viscometer is a highly precise instrument used to determine the viscosity of aspirated liquids. Viscosity is essentially the resistance of a liquid to flow. For example, honey has a higher viscosity because it flows slowly while water has a lower viscosity because it flows quickly. The viscometer is a capillary tube (usually made of glass). The tube is put inside a vacuum chamber, so it is less affected by air resistance and the measurements can be more accurate. The liquid first placed in the capillary starts to flow through the tube. It is important to note that the liquid is influenced both by its viscosity and gravity


The time taken for the liquid to move a certain distance inside the capillary is measured. And the thicker the liquid, the longer it will take. If there is a reference chart, you can use the measurement to check the exact viscosity of the fluid. This device is a common tool in many areas such as product testing in the food industry or ensuring that oil is of the correct viscosity for engines. When it comes to precision and reliability, ZONWON's vacuum capillary type viscometer lead the pack as they employ state, of, the, art technology.
