The Untold Stories of Laboratory Chemicals In Lab Settings

Posted on the 5th of Mar 2024 by Westlab

With all the integration of technology in scientific research, one thing that has not changed yet is the use of chemicals. These acidic or alkaline chemicals can help scientists to find answers to their complex questions. It increases the speed of reactions, changes its colours or makes a new solution to enable science to help humanity. Simply put, these Laboratory Chemicals have been the best friends of scientists for ages. 

Lab chemicals are of different kinds and grades. Some are highly concentrated and only used in sensitive environments with all safety measures. However, some are diluted or less graded. These chemicals or reagents can accelerate the process but need fewer safety precautions than the concentrated ones. If a researcher is about to experiment, he should know the type and Grade of Chemicals he might need.

What Is The Role Of Laboratory Chemicals In Modern Science?

Lab Chemicals are much more than just parts of bubbling experiments. They are the essential elements that lead to scientific breakthroughs. These everyday substances are key players in many scientific areas, pushing forward knowledge and new ideas in many fields. 

Let us take a closer look at their important roles.

  1. Material Science: Chemicals are needed to invent new materials with specific qualities. Without the right chemistry recipes, we would not have polymers, ceramics, or advanced composites.
  2. Discovering and Making Drugs: Chemicals are crucial to finding and making new medicines. Whether it is creating potential new drugs or testing how effective they are, chemicals are at the heart of making antibacterial agents, antibiotics, and other critical medicines.
  3. Checking for Pollutants: Different Grades of Chemicals are important for keeping an eye on the health of our environment. They help find air, water, and soil pollutants, which lets us clean up and protect our surroundings.
  4. Give Sustainable Ideas: Scientists use chemicals to develop greener ways to do things and make products. Everything from biodegradable plastics to renewable energy and alternative fuels comes from complex chemical reactions and designs.
  5. Cutting-edge Tech: From tiny nanotech devices to the vast potential of quantum computing, the development in these areas heavily depends on unique chemicals with particular characteristics.
  6. Space Exploration: Understanding chemical reactions in extreme conditions expands our universe knowledge and helps develop new tech for exploring space. Chemical grades can change the whole perspective of the learning universe, so scientists rely heavily on these chemicals.

Therefore, it is evident that from the old-school obsolete experiments to space exploration, these Guide To Laboratory Chemicals are indispensable. Researchers spend their whole lives learning the behaviour of these chemicals in small experiments. Whether it is modern science with technology or a minor experiment with a Bunsen burner, these chemical substances can change the whole result with one drop. 

Types Of Chemicals Used In Lab According To Grades

In labs, chemicals are sorted by their purity levels, which helps decide what research or tests they are best for. Knowing about these purity grades is essential to ensure that experiments are accurate and safe. 

Let us look at the main purity grade types for lab chemicals.

Analytical Grade

These are super pure chemicals used in labs where the researcher needs to be precise, like when measuring or identifying chemicals. They are usually 99.9% pure or more, although this can change a bit based on who makes them and their proper storage. Hydrochloric Acid (HCL), Sulfuric Acid (H2SO4), and Nitric Acid (HNO3) are its prominent names. 

Reagent Grade

Also very pure, these chemicals are used for chemical reactions and tests where any impurities could mess up the results. They are suitable for a lot of different lab work. A bit less pure than analytical grade, generally over 98% pure. Chloroform, acetonitrile and Isopropanol are basic reagent-grade chemicals. 

Technical Grade

These chemicals are not as pure and are meant more for industrial use than precise lab experiments. They are used when researchers do not need everything to be super accurate or flammable. Their purity varies greatly, usually around 85-90%, so they are not great for detailed lab work but fine for making things in large batches. Acetone and Ethanol are the biggest examples of technical-grade chemicals. 

Pharmaceutical Grade

These high-quality chemicals meet specific standards for making drugs and medical research. They have to follow strict rules about how they are made and handled. Very pure, without any harmful impurities, to ensure they are safe for pharmaceutical use. Aspirin, Salicylic acid, and Sodium chloride are some of its common examples.

Laboratory Grade

It is suitable for general lab tasks but not the best for precise experiments. These are often used in schools or for basic lab tests. It is not as pure as analytical or reagent grades, and the exact purity level can depend on the manufacturers. Sodium bicarbonate, Calcium chloride, and potassium permanganate are some lab-grade chemicals. 

Food Grade

These chemicals are safe to eat or use in making food. They are not used for lab analyses but have to be clean enough not to be harmful. Pure enough to be safe to eat or touch food, focusing more on being harmless than on a specific purity number. Acetic acid, sodium bicarbonate and sodium chloride are the top food-grade chemicals.

Laboratory chemicals play a vast and widespread role in today's science. They are not just used for finding out new things and exploring, they are the base that helps us learn more, improve technology, and make society better. As science keeps moving forward, the need for lab chemicals to help with new ideas, tackle big world problems, and push forward progress is clear and undeniable.

1. What do chemical grades mean?

Grades mean the purity level of any chemical that gives the scientists a better understanding of its potential reaction in the experiment. 

2. What are the names of the grade of chemicals?

Analytical, technical, pharmaceutical and food grade chemicals are some of the prominent types of grading in chemicals. 

3. What are the benefits of using different grades of chemicals?

Different grades offer different ranges of consistency, safety and accuracy in the experiment. Make sure the grading before using any chemical in the lab.
