What is a "beaker"?

A beaker is a wide, cylindrical container used in laboratories for mixing, heating, or holding liquids and chemicals. It is typically made of glass or plastic and has a flat bottom for stability. Beakers often have markings on the side to show measurements, making it easier to measure and pour liquids accurately. They usually have a small spout at the top for easy pouring and are commonly used in science experiments or in classrooms to perform basic chemical processes or mix substances.

What is a "pipette"?

A pipette is a small, tube-like tool used to transfer or measure liquids in precise amounts. It is typically made of glass or plastic and has a narrow, long shape with a bulb at one end. The bulb is squeezed to draw liquid into the pipette, which can then be released by squeezing the bulb again. Pipettes are commonly used in laboratories, especially in experiments that require accurate measurements of liquids, such as in chemical reactions or medical testing. Some pipettes are graduated to show different volumes, while others are used for transferring a fixed amount of liquid.

a device that spins samples to separate components based on density

What is a "centrifuge"?

A centrifuge is a device used in laboratories to separate substances of different weights from a liquid mixture. It does this by spinning the mixture very quickly, causing heavier materials to move outward and leaving lighter materials closer to the center. This process allows scientists and researchers to separate and study substances like cells, proteins, or DNA in biological samples. Centrifuges are essential tools in various scientific fields for performing tests, experiments, and analyses efficiently.

существительное

the process by which microorganisms convert carbohydrates into alcohol, acids, or gases

What is "fermentation"?

Fermentation is a natural metabolic process that converts sugars into acids, gases, or alcohol, often with the help of microorganisms such as yeast or bacteria. In the context of food and beverages, fermentation is commonly used to produce a wide variety of products, including bread, cheese, yogurt, beer, wine, and sauerkraut, among others. During fermentation, microorganisms break down the sugars present in the starting material, releasing energy and producing byproducts such as carbon dioxide, alcohol, or lactic acid. These byproducts often contribute to the flavor, texture, and preservation of the final product. Fermentation can occur spontaneously in some cases, but it is often carefully controlled and monitored in food production to achieve consistent results and ensure food safety.

What is a "condenser"?

A condenser is a laboratory device used to cool and condense vapors back into liquid form. It typically consists of a tube through which vapor passes, surrounded by a layer of cold water that cools the vapor as it moves through. The cooled vapor then turns back into liquid and can be collected in a separate container. Condensers are commonly used in distillation processes, where heat is applied to a liquid to separate its components, and in other experiments that involve heating and cooling substances. The cold water helps ensure the vapor does not escape.

What is "biodiesel"?

Biodiesel is a type of fuel made from natural oils, such as vegetable oil or animal fat, that can be used in diesel engines. It is considered a cleaner alternative to regular diesel because it produces fewer harmful gases. Biodiesel can be used on its own or mixed with regular diesel. Since it is made from renewable sources, it helps reduce reliance on fossil fuels. However, producing biodiesel requires land and resources, which can affect food production and the environment.
