(pipete)
pipeta
a laboratory tool used to measure and transfer small volumes of liquid
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.
(centrifugadora)
centrífuga
a device that spins samples to separate components based on density
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.
(tablero periódico)
tabla periódica
a tabular arrangement of chemical elements organized based on their atomic number, electron configuration, and recurring chemical properties
disolverse
(of a solid) to become one with a liquid
Información Gramatical:
(cristalizado)
cristalino
denoting substances with a highly organized molecular structure, akin to crystals
(densidad)
concentración
the measure of how much of a substance is present in a certain volume of solution
(nanotubos de carbono)
nanotubo
a tiny, tube-shaped structure made of carbon atoms, with remarkable strength and electrical properties
(líquido)
fundido
heated to a liquid state due to high temperatures
(grupo radical)
radical
a group of atoms bonded together that behaves as a single unit within a molecule
(estado)
fase
a phase is a distinct form of matter with uniform chemical and physical properties, separated from other forms by boundaries
(endurecimiento por calcio)
calcificación
the process where calcium or calcium salts accumulate in a tissue, making it hard and rigid
(fermento)
fermentación
the process by which microorganisms convert carbohydrates into alcohol, acids, or gases
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.
(detoxificar)
desintoxicar
to eliminate or neutralize harmful substances
Información Gramatical:
ensayar
to analyze or test a substance, typically in a laboratory setting, to determine its components or qualities
(Cristalógrafa)
Cristalógrafo
a scientist who studies the structure and properties of crystals
(técnica de separación de compuestos)
cromatografía
a laboratory technique used to separate and analyze mixtures of substances based on their differential affinities for a stationary phase and a mobile phase
(decayo beta)
desintegración beta
a type of radioactive decay where a nucleus emits a beta particle (electron or positron) to transform a neutron into a proton or vice versa
(no cargado)
sin carga
not having an electrical charge
(valoración)
titulación
a laboratory method used to determine the concentration of a substance in a solution by gradually adding a reagent of known concentration until a reaction is completed
(estado de equilibrio)
equilibrio dinámico
a state in a chemical reaction where the forward and reverse reactions occur at the same rate, resulting in no net change in the concentrations of reactants and products
(condensery)
condensador
a device that turns vapor into liquid by cooling it
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.
(interacciones de van der Waals)
fuerzas de van der Waals
weak attractive forces between molecules or atoms, arising from temporary or induced dipoles
(especialista en metalurgia)
metalurgista
a scientist or engineer who specializes in the study and production of metals and alloys, including their properties, processing methods, and applications
(adsorción superficial)
adsorción
the process by which molecules of a substance adhere to the surface of a solid or liquid, forming a thin film or layer
(biocombustible)
biodiésel
a renewable, alternative fuel made from organic materials such as vegetable oils, animal fats, or recycled cooking grease
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.
electrólisis
(chemistry) the process of separating a liquid or solution into its parts by passing electricity through it
(dispersar)
suspender
to disperse fine particles throughout a fluid so they remain evenly distributed without settling
Información Gramatical:
