One Step Closer To Perfection In Thermal Analysis

Thermal analysis, as the name suggests is analyzing the change in the properties of materials when they are subjected to different temperatures. Different techniques are used and the response of the material is then plotted as a function of temperature and time. This is an indispensable branch of materials science. It is crucial to determine the way a substance reacts to a change in temperature.

Who does this impact?
Food companies use it to know the optimum temperature to store their products without spoiling. Oceanographers want to know if the temperature at the bottom of the sea will affect the equipment they use. Software companies need to know what is the exact range of temperatures that will keep both their machines as well as their employees happy and working. Engineers will also want to check out if the bridges that they build will survive the expansion and contraction due to the temperatures they are subjected to.

Due to such a wide area of application, instruments used in the various different methods of thermal analysis are carefully calibrated and made highly sensitive to aid researchers in the best possible way.

Does vibration affect thermal analysis instruments?
As an example of how vibrations can affect your thermal analysis instruments, let us consider a test in one method of thermal analysis called Thermogravimetric analysis. The test we will consider is the ‘Blank Test’.

This is a test of the apparatus without the sample material in it. The Blank Test gives us an idea of the health of the instrument we are about to use and is thus a necessity in thermal analysis. When we run such a Blank Test, we plot a curve of the changes in physical and chemical properties against an increasing temperature. This curve is also called the Thermogravimetric Analysis curve(TGA Curve) and is affected by noise present in the equipment.

Various factors that contribute to the noise may be the touching together of the different minute components within the apparatus which can occur due to external vibrations. Hence, an inaccurate TGA curve is obtained.

magnifying microscopes

Magnifying Microscopes

Over the years, microscopes have evolved from being magnifying glasses (then also called ‘flea glasses’ as they were mostly used to look at tiny bugs) to becoming complex equipment with adjustable powers. Today, they are one of the most commonly used apparatus in laboratories.

Where can they be used?
They are used to view anything from samples of minerals to cells of the human body: anything that is too small to be seen by the naked eye but must be observed for the purpose of scientific research or for commercial ventures. Chances are, if you have a lab, you have a microscope sitting snugly in it somewhere.

The microscope consists of lenses that serve to magnify the sample and send it to the eyepiece, to be viewed by the observer. Light microscopes use light to pass through the sample and view images, while electron microscopes use powerful electron beams instead of the light. Scanning acoustic microscopes, Fluorescence microscopes, and X-ray microscopes are also some of the other types of microscopes in use.

Do vibrations affect microscopes?
The term resolution is what most aptly describes the capacity of the microscope to accurately differentiate between 2 points in the sample. It is measured by the shortest distance between these 2 points and powerful microscopes can differentiate even up to nanometers. However, this robust looking device is also extremely sensitive. It is not left unperturbed by the vibrations in the environment around it. Studies show that even the footsteps of a person walking on the laboratory floor can significantly affect the image viewed from a high-resolution microscope. Needless to say, vibrations from vehicles passing by outside the lab as well as from other equipment within the lab also affect the resolution. Many times, the readings from other machines that work based on this microscope’s readings are more affected by these vibrations.

What is a solution to these vibrations?
Hence, there is a need to place the microscope on a stable bench that can minimize these vibrations and improve the quality of the readings. The anti-vibration properties of the working bench can significantly improve the accuracy of the readings involved.

Pulverising with Planetary Ball Mills

Pulverising with Planetary Ball Mills

Planetary Ball Mills
Ball mills are used the world over in material processing plants, for grinding and mixing materials using steel, rubber or ceramic grinding media. This uses the forces of impact and friction with balls within the jar to mix ingredients and reduce particle size.

What are planetary ball mills?
While the traditional ball mill is a large cylindrical structure used for making paints, ceramics or building materials, there is also a much smaller looking ‘planetary ball mill’ that works on the same principle and can be used in your laboratory. Planetary ball mills come for smaller quantities, but can be used for pulverizing the feed mixture to high levels of fineness, even up to the nano range. This is achieved by an interplay between friction and impact forces that cause high energy levels to be generated within the machine. This mixes up and breaks down the material and gives very fine results.

How do they work?
The machine has at least one grinding jar that is arranged so that it rotates in the opposite direction of an eccentrically located sun-wheel. Grinding balls within the machine’s grinding jars break down the material that is fed in, into very fine particles using the so-called ‘Coriolis forces’, which are basically forces due to superimposed rotational movements.

Vibrations caused and the solution:
However, such large amounts of energy involved can mean huge vibrations too. Planetary ball mills manufactured today compensate for these with Free Force Compensation Sockets(FFCS) . These are especially useful for long-term grindings, and ensure that the machine stays put on the working bench, even if it is left unattended. These sockets are placed in the feet of the machine and are based on d’Alembert’s principle. They allow a small movement of the machine’s outer housing, which in turn allows an automatic compensation of the machine vibrations with its own mass. As a result, the working platform gets a smaller amount of the vibrations through the feet.

Do you have a planetary ball mill running, whose vibrations affect other machines? Or is it some other larger machine causing vibrations in your lab, affecting overall performance?

Semi Microbalance

A semi-microbalance is a small mass measurement device that can support weights of up to one hundredth of a milligram. Semi-microbalances provide precise measurements when you need a readability that reaches five decimals places as opposed to the four decimal places typically featured in regular analytical balances. When you are responsible for delivering accurate results, you need to make sure the equipment you are using can provide you with consistently accurate results.

The primary factors that you need to compare among standard microbalances are:

– Capacity

– Linearity

– Stabilization time

– Calibration type (internal vs. external)

All of these characteristics can impact the final result of your measurements so you want to pay close attention to the specifications for every semi-microbalance you consider. You don’t want to make any mistakes when taking your measurements, so make sure your semi-microbalance features a user-friendly control pad and display.

What are the pros of using a semi-microbalance?

When you opt for a semi-microbalance, you increase the precision of your measurements, as compared to a standard microbalance. A semi-microbalance that provides quick and accurate measurements will make your lab more efficient and increase productivity.

What are the cons of using a semi-microbalance?

The only real drawback of using a semi-microbalance is in those instances where you require smaller measurements. As scientific research continues to evolve, weighing samples will get smaller and smaller. At some point, you might need to replace your semi-microbalance with an even smaller measuring device.

www.antivibrationtable.com provides working platforms for all types of balances.

Laboratory Analytical Balance

What is a Standard Micro Balance

The standard micro balance will usually provide precise measurements up to 22g. When you want overall performance and quality in order to obtain consistent and reliable small mass measurements, a standard micro balance will most likely be the right option for you.

The primary factors that you need to compare among standard micro balances are:

– Capacity

– Readability

– Response time

– Repeatability

You also want to look at things like user-friendliness and how easy the balance is to clean and maintain.

What are the pros of using a standard micro balance?

A standard micro balance will give you exact measurements when weighing very small amounts. You can increase the services offered in your lab simply by adding a standard micro balance. Weighing small samples is impossible on regular scales. By investing in a micro balance, you can ensure that your small measurements are always right the first time. Avoid transfer errors and save your lab a lot of money, especially if you are handling expensive materials.

What are the cons of using a standard micro balance?

With a standard micro balance, you wont be able to obtain the lowest possible measurements. There are balances out there that can support an even lower weight capacity than an average micro balance can. While this might be considered a limiting factor to some people, a standard micro balance might provide you with all the functionality you need.
