Spectrophotometer

What is a Spectrophotometer?

Detecting a chemical compound without a spectrophotometer never being easy. That why every chemistry lab is equipped with this analytical device. Spectrophotometer works by separating the spectral of light and measure its component intensity. Since some chemicals absorb light thus the intensity of the adsorption can be measured by using a spectrophotometer and its concentration could be quantified. Light Light is some sort of electromagnetic radiation emitted from its sources. It could be light from the candle, lamp, sunlight reflected… Read More »What is a Spectrophotometer?

Flu Pandemic

Ways to Prevent Flu Pandemic

Nobody wants to get infected with the flu sickness. But we often cannot avoid them. On average we were infected once a year and it takes 1 week to fully recover. Flu is categorized as infectious diseases caused by viruses. It easily transmitted through air and physical contact. The recent flu pandemic by COVID 19 was not expected. The outbreak is uncontrolled. Thus, the whole world is forced to stay at home for months with millions of death. Also The… Read More »Ways to Prevent Flu Pandemic

Sustainable and Alternative Chemical Sources

Concern on oil depletion and global warming has shifted us to sustainable alternative energy such as solar and wind energy. But we could not stop just yet to produce chemicals from petroleum oil. Chemicals are essential building blocks for us to make fabric, plastic ware, container, paint, solvents, shoes, carpet, medicine, flavor, fragrances, additives, and much more. There is a various option for energy sources, but there are no sustainable alternative chemical sources just yet. Without chemicals, our lifestyle would… Read More »Sustainable and Alternative Chemical Sources

Exothermic & Endothermic Reactions

Exothermic reactions are chemical reactions that release energy. The energy release usually in the form of heat. While endothermic reactions are chemical reactions that absorb energy. Any elements or compounds in existence within a specific system needs the energy to maintain its state. If a compound wants to change to another product they need to release or absorb heat to meet the requirement of the new products. Exothermic reaction If the level of energy of the product is less than… Read More »Exothermic & Endothermic Reactions

Alternative Source for Chemicals

Concern on oil depletion and global warming has shifted us to alternative energy such as solar and wind energy. But we could not stop just yet to produce chemicals from petroleum oil. Because chemicals are essential building blocks for us to make fabric, plastic ware, container, paint, solvents, shoes, carpet, medicine, flavor, fragrances, additives, and much more. There are plenty of options for energy sources, but there are no alternative sources for producing chemicals. Without chemicals, our lifestyle would not… Read More »Alternative Source for Chemicals

Good Hand Sanitizer

In the event of a pandemic, people are more aware of good hygiene and health-conscious to stay from infection. This causes the price of health sanitizer to skyrocket and event out of stock. Actually, making a hand sanitizer is not too difficult. We could make it at home by mixing alcohol with either propylene glycol, glycerine, or aloe vera gel. But, how to be sure that our homemade hand sanitizer works. Purpose of hand sanitizer The purpose of hand sanitizer… Read More »Good Hand Sanitizer

Yeast for baking

How Yeast Works

Yeast is a single cell microorganism. This tiny living creature has been used for baking and brewing through the fermentation process since ancient times. Without it, we might not discover the bread! Yeast is definitely important for us in making our food and we continue to use it even today. It can be found everywhere, in the store. The most common yeast sold in-store is cells called Saccharomyces cerevisiae in a dry form. It looks like a powder, but it… Read More »How Yeast Works

Glass making blowing

Glass Making Process We Never Thought

We use glass as glassware, dishware, bottles, windows, and even a wall. The unique properties of glass to be transparent, chemically stable, and can withstand high temperatures make them useful for our daily usage. Surprisingly, glass is made from the sand! How they make it, is something we never thought. Egyptians and Mesopotamians had used glass before us. You might be puzzled how they made this before the century. Sand can be transformed into the glass because it has silicon… Read More »Glass Making Process We Never Thought

How Many Times Cooking Oil Could be Reuse

We love frying food because of the taste and texture. It looks delicious! I do love crunchy and crispy fried potato or fried chicken. Who does not, you really have weird taste. Get a doctor! For those who did kitchen work, it quite often we reuse the cooking oil because we don’t want to waste it. Especially when we are running a food business. We want to cut costs, reuse cooking oil does matter. Do you ever wonder how many… Read More »How Many Times Cooking Oil Could be Reuse

Know Your Rubber Glove

Have you ever wear a glove before? If not, you definitely not a doctor, nurse, or scientist. I still remember back at school, my chemistry teacher asked me to use a glove while doing an experiment even though it too huge for my hands. But it does the job! protecting your hand. These days glove is essential items, not just for hospital and lab workers. It also for those handling food & beverages or customer services. Because gems, bacteria, and… Read More »Know Your Rubber Glove
