/0 Comments/in /by

Viscometer is a tool to measure the level of viscosity of liquid substances. Viscosity itself is a measure of the level of viscosity of a liquid or called a fluid. The level of viscosity of the fluid is very necessary in order to know the flow properties of the liquid. The viscosity level is measured using a cylindrical tube.

The use of a viscometer is very often used laboratory equipment. Its function is to measure liquid in laboratory studies. There are many types of viscometer that are often used for research. Although the main function of the viscometer as a measure of viscosity of liquid, each viscometer also has another function that is different from one another.

There is a viscometer to measure how long it takes liquid to flow and reach a certain mark. There is also a viscometer that is used to measure the force of gravity and also the calculation of the frictional force. Then there is a viscometer to measure the absolute viscosity of the liquid.

Some viscometers that are frequently used are Viscometer Stormer and Viscometer Brookefield. These two viscometers have in common that can be used to measure the level of rheology and viscosity of liquid in Newton’s and non-Newton’s systems. Rheology itself is a picture of solid deformation and also the flow of liquid.

Then what is the main function of Viscometer Stormer and Viscometer Brookefield? How do the two viscometers work? And is there a difference between Stormer and Brookefield? You can see the info below.

Definition of Stormcom Viscometer

Viscometer Stormer is a viscometer used to measure the degree of viscosity of substances present in paint. Viscometer Stormer is often used by paint products companies. The workings of this viscometer measure through the speed of rotation of the liquid.

Understanding Viscometer Brookefield

Viscometer Brookefield is used to measure the thickness of a liquid in a simple way. Brookfield is often used because the way it is used is very easy and the results of measurements using this tool are quite accurate and precise.

Difference between Stormer and Brookefield

Although these two tools have in common to measure the viscosity of liquids, the two viscometers also have different functions. It can be seen from the above review that the main difference between the two viscometers is the working principle of this viscometer. Viscometer Stormer measures the rate of rotation of the liquid while Brookefield measures the flow of the liquid being studied.

The way the Viscometer Brookefield works is quite easy. All you have to do is place the sample on the instrument and wait for a few minutes to reach a certain temperature. After that you can record the results that appear in accordance with the standards.

Whereas the Viscometer Stormer has a liquid stirring rotor as its main mechanical. If the rotor rotates faster then it indicates that more shear stress samples are above the yield value.

If the Stormcom Viscometer is widely used in paint products companies, Brookefield Viscometer is more widely used in mineral water products companies. This shows that the application of the two viscometers is intended for different products.

From some of the reviews above, we can find out that Viscometer Stormer and Viscometer Brookefield have different functions and ways of working, even though they both have working principles in accordance with the Non Newton system.

Brookfield Viscometer for Measurement of Liquid Substances in Chemistry Laboratories

/0 Comments/in /by

Chemical laboratories are known as places used to conduct research on chemical objects. Many research tools are in the chemistry laboratory. One important tool that must be available in a chemical laboratory is a viscometer. Viscometer is used as a tool to measure the level of viscosity.

Viscosity is the level of viscosity in the liquid. Interactions that occur in liquid molecules due to motion that ultimately form the level of viscosity. Viscosity flows through a pipe called a glass pipe.

The viscosity level can be seen from the fluid flow motion, if the liquid flows quickly, the viscosity level of the liquid is low. But when the liquid flows slowly, the viscosity level can be said to be high. An easy way to measure the flow rate motion is to use a cylindrical tube.

This measurement uses a viscometer. Viscosity cannot be measured without using a viscometer. This makes the viscometer very important especially for chemical laboratory equipment which often conducts research on liquid substances. So what are the benefits of a viscometer and how does the viscometer work in a laboratory? You can see the review below.

Benefits of Viscometer

Viscometer has many benefits for life. The level of viscosity of a liquid is very important to measure so that it can be known whether the liquid is an ideal liquid or not. One company that uses a viscometer as a tool in its production is a company that produces mineral water. The company uses a viscometer to measure whether their mineral water products are ideal or not.

Different types of viscometer are used

Viscometer has a variety of types. Each viscometer has a different way of working according to the needs of the study. There are four types of viscometers that are most commonly used. The viscometers are Viscometer Brookefield or often called Viscometer Cone and Plate, Viscometer Ostwald, Vidcometer Hoppler, Viscometer Cup and Bob.

But the most modern and sophisticated of the three viscometers is Viscometer Brookefield. Its use is simple but able to measure the level of viscosity accurately making this viscometer the most widely used viscometer in chemical laboratories.

Functions and Ways to Use the Brookefield Viscometer

Viscometer Brookefield is used to measure the level of viscosity in liquid substances that have small volumes. Only by using a small sample, Viscometer Brookefield can give very precise results to the liquid being tested. This is what makes Viscometer Brookefield very widely used in chemical laboratories. In addition, Brookcomield Viscometer can also save time when the process is filled during the trial period. This tool also has a more stable temperature than other tools.

Before using Viscometer Brookefield, you need to know what things can affect the results that emerge. These things namely :

  • The size of the sample used
  • Cleanliness of the plate and also the cone
  • The size of the particles, materials, and also high and low levels of viscosity
  • The duration of time for the sample to stabilize the plate
  • Cone type so the results are more accurate
  • Rate on the sample

How it works viscometer is also quite easy. The first thing you have to do is adjust the distance of the plate with the cone spindle according to the instructions. Then you choose a standard of viscosity ranging from 10% to 100%. You better choose a standard value of 10% of the Full Scale Range (FSR).

After that you can enter the sample to be used in the cup. Then allow 15 minutes to reach the set temperature. Then you can take measurements. After the measurement process is complete you can record the results that appear starting from cP and% Torque.

From the review above we can find out that Viscometer Brookefield is very important for the process of measuring liquid in the chemical laboratory. Hopefully the above review can be useful especially for those of you who often do research in the laboratory.

Theory and Application in Fall Ball Viscomometers

/0 Comments/in /by

A production process, usually requires several chemical laboratory tools that are useful to help facilitate the process. In addition to facilitating the production process, the tool is also useful for maintaining the quality of the dose of a product. Especially when you are struggling with liquid material. Given one of the properties of liquid objects is very easily affected by temperature.

So a production that uses liquid material certainly requires a tool that can measure the level of precision of the liquid. Among the many tools for measuring fluid, a viscometer is the most important.

What is a Viscometer?

A viscometer is a device used to measure viscosity. Viscosity is the resistance of movement of liquid objects. High viscosity liquids will flow much more slowly than low viscosity fluids. An example is the oil flow rate compared to the water flow rate when both are at the same room temperature.

When working with liquid objects in a production, knowing the viscosity is very important. One reason is as a quality control of the liquid. If there is no viscosity control, a product cannot be guaranteed quality.

You may be familiar with Zahn’s cup, which was discovered by General Electric in 1936. Zahn’s cup is a kind of cup-shaped efflux viscometer. Here are the types of Viscomometers that you need to know:

  • Viscometer hole
  • Capillary Viscometer (U tube)
  • Piston viscometer falling
  • Rotational viscometer
  • A falling ball viscometer
  • Vibration viscometer

Why is a Viscometer Important?

A viscometer will help you ensure that the viscosity of your liquid is in the precise amount required. A viscometer will help you get consistent results. In a production, consistency is the key to good product quality.

As mentioned before, without viscosity measurements you will experience a number of problems in the dose. The treatment at high viscosity will be different from the low viscosity treatment. If you don’t do this you may experience problems such as inconsistent color changes, excess waste, excessive use of solvents, and other unexpected quality imperfections.

A customer certainly will not be happy with a product that has inconsistent quality. That is why it is very important to monitor the viscosity in your production process.

Falling Viscometer and Its Working Principle

In this article, we will focus more on discussing falling ball viscomometers. In 1932, Fritz Höppler was granted a patent for his discovery, the falling ball viscometer. The world’s first falling ball viscometer was developed by Fritz Höppler in Medingen, Germany. Höppler applies the principle to measuring the viscosity of liquids as Newtonian measures the time it takes for a ball to fall down (gravity).

Höppler measures the viscosity of the liquid through a tube tilted to a certain degree. To determine the viscosity value of a liquid, three tests are performed, the average time on the three test tests is processed using a simple formula until it becomes a viscosity value.

Falling ball viscometer tubes are mounted on shaft bearings which quickly allow tube rotation up to 180 degrees. This allows several tests to be carried out in a short time.

The falling ball viscometer is very suitable for measuring fluid viscosity. This method has been stated in international standard 4.5. Brizard et al. 6 developed an absolute falling ball viscometer. This method considers the effects of edge, inertia, etc. And correct the measurement results to achieve relative uncertainty in the order up to 0.001.

Although the falling ball method has been well developed and stated in international standards, it is rather uncomfortable to operate this type of viscometer. For example, a viscometer requires six balls of different diameters to measure various viscosities, and the user has to do a test to choose a suitable ball. In addition, it is difficult to determine where the falling ball arrives at terminal speed, that is, whether the distance between the starting line and the starting position is sufficient.

Apart from all that, the falling ball viscometer has various advantages, such as shaft bearings that allow quick and easy tube rotation (ideal for repeated testing), connections to the circulation bath to control sample temperatures very well, a six-ball set that is useful for testing various samples, complete with temperature checks, and accuracy reaches 0.5% to 2.0% depending on the ball used.

Falling ball viscometer is suitable for quality control in various industries as well as in academic institutions that require scientific method approaches.

That was a brief explanation of the viscometer especially the capillary viscometer, which is certainly very useful for measuring the level of precision and maintaining the quality of your product. That way, you don’t need to worry about the quality of your product.

Capillary Viscometer and its Working Principle

In this article, we will focus on discussing capillary viscometers. Capillary viscometer is also known as U tube viscometer, which consists of a U-shaped glass tube with two balls (one higher and one lower). Capillary viscometers are categorized into three groups, namely:

  • Oswald type, which in various forms are designed for clear (transparent) liquid.
  • Suspended Level type, where the capillaries are useful to ensure the same air pressure, regardless of the volume of liquid that is inserted into the viscometer varies.
  • Reverse flow type, suitable for opaque liquids.

Each of these categories has a number of sets of viscometers named after the discoverers. Each type of Ostwald and Suspended Level has seven types of viscometers0,2-20,000 mm2 / s dan 0,3-100,000 mm2 / s. Whereas this type of backflow has 4 sets of viscometers with a range covering up to 300.000 m2 / s.

This type of viscometer is very easy to use. The principle works, the liquid will flow from the higher ball to the lower ball through the capillaries. The viscosity of the liquid is measured by calculating how long the fluid / liquid passes through the tube. Capillary viscometer is very good for measuring the viscosity of oil type liquid.

That was a brief explanation of the viscometer, especially the capillary viscometer, which is certainly very useful for measuring the level of precision and maintaining the quality of your product. That way, you don’t need to worry about the quality of your product.
