These are the Principles of Falling Viscometer Work that Must Be Known

In the laboratory, there are tons of tools you find that are related to research. One of them is a viscometer. A viscometer is a device used to measure the viscosity of a liquid solution. The viscosity of a liquid solution is the viscosity or internal friction in the liquid. The higher the viscosity level of a liquid, the more difficult it is to move from one point to another. Conversely, the lower the viscosity of a liquid, the faster it moves from one point to another.

To calculate the level of viscosity of liquid, the instrument used is a viscometer. One of them is a falling ball viscometer. The working principle of the falling ball viscometer is how the viscosity is calculated by looking at how long it takes by the ball to move from one point to another. Here’s the full explanation!

Knowing what viscosity is

As explained above, viscosity is the level of viscosity or internal friction in the solution. In a solution or liquid, there is such a thing as movement within the liquid itself. This movement produces internal friction. When the internal friction in the liquid is very high, the level of viscosity of the liquid becomes high. Meanwhile, when the level of friction in a liquid is low, the viscosity level is low.

Then, what is the effect of viscosity or viscosity level on liquid substances? The level of viscosity will affect the speed of movement of a liquid. When viscosity is high, liquid is more difficult to move and takes a long time to move. Conversely, when viscosity is low, liquid is easier to move and requires less time to move.

Easy examples are water and oil. Water has a viscosity of lace so it moves quickly. Meanwhile, oil has a high viscosity making it more difficult to move or move. When you move water and oil from one container to another separately, which is faster? Of course water. Water will move more quickly from one container to another than oil. This is the purpose of viscosity, to determine the level of viscosity and speed of the liquid moving matter.

Viscometer function

Now that you understand the principle of viscosity, it is time to understand about the measuring device. Viscosity of liquid can be measured and known from a device called a viscometer. Viscometers see the speed of liquid flowing through a glass capillary. Usually this is made of glass pipes with a small diameter.

The viscometer will see how fast the liquid is flowing. You can enter the sample of the liquid you want to know the viscosity into the viscometer. When the viscometer is running and it turns out the solution is moving fast, then the viscosity is lace. Otherwise, the viscosity is high. Nowadays there are many types of viscometers. Including one of them is a falling ball viscometer.

The working principle of the falling ball viscometer

A falling ball viscometer is a viscometer used to measure the viscosity of Newton’s liquids. The working principle of the falling ball viscometer is at one point the sliding speed. Simply, the working principle of a falling ball viscometer is to see how much time it takes for the ball to move from one point to another when it is put in a different solution.

The falling ball viscometer will be filled first by a liquid or solution. The shape of the falling ball viscometer itself is a small transparent tube that makes it easy for you to see what is happening inside it. Then, after the solution has entered, the ball will be inserted. When the viscometer is upright, the viscometer is reversed 180 degrees so that the top of the tube becomes the bottom and the bottom of the tube becomes the top.

The working principle of the falling ball viscometer is to see how long it takes the ball to fall from the bottom to the top after it is flipped. If the ball takes a few moments to turn around. Then the solution is thick with high viscosity. If the ball falls directly (as in aqueous solution) then the viscosity level of the solution is low with the same low viscosity.

How, are you now familiar with the working principle of the falling ball viscometer? If you need a falling ball viscometer for research needs, you can contact Infiniti Bioanalitika Solusindo (IBS) because we provide a variety of laboratory equipment that is useful for you.
