How do evaporating dishes work?
See more now. Evaporating dishes are used to separate water and solids from a solution by allowing the water to evaporate off into the air.
What equipment is used to measure volume?
What lab equipment is used to measure volume? If volume precision is important, then a volumetric flask would be the most suitable glassware. Volumetric flask has a flat base, and its bottom resembles a bulb. It has a long elongated neck that is marked. The mark on the volumetric flask is the liquid's end point. Graduated cylinders are glassware equipment used in measuring the volume of liquids. Such apparatuses resemble narrow scaled cylinders with a small beak at their open end. The beak reduces the chances of spilling, and makes the transportation of liquids easier. Burettes resemble graduated cylinders, so expect that they are extremely narrow. Burettes are used mainly in titration processes, or for simply dispensing a liquid of a known volume. Burettes are supported by a ring stand, clamp, and utility clamp.
What is the purpose of a volumetric flask in chemistry?
Others are designed for several functions, like the volumetric flask. The volumetric flask is used to prepare solutions with accurate volumes, and it can be used to mix solutions.
What is a volumetric flask?
Volumetric flask: a sufficient amount of solvent is poured, then the solid is added. The flask is filled with solvent until its mark, then it is sealed with a stopper and inverted continuously.
What is a Florence flask?
A Florence flask is a glassware that resembles a bulb, and it is used for heating and holding substances as they undergo chemical reactions.
How to secure mortar to pestle?

What is an Erlenmeyer flask?
Erlenmeyer Flask, also known as a conical flask, is glassware comprising of conical body, flat bottom, and a cylindrical neck. It is one of the most commonly used flasks to carry out various experiments in the chemistry lab, such as titration, filtration, crystallization, etc. It was first patented in 1860 by a German chemist, Emil Erlenmeyer. The slanting sides and wide base of an Erlenmeyer flask make it a perfect conical vessel to mix the chemicals by swirling without any risk of spillage. Additionally, the cylindrical neck of a conical flask can accommodate a glass stopper, and it also provides support to fit funnels. Based on the application, an Erlenmeyer flask can either be graduated or unmarked. Moreover, it can also be used for heating and boiling purposes.
What is a retort flask?
The retort flask is an oddly shaped airtight glassware with a curved neck. Although retort flasks are no longer employed in current chemistry labs, they were employed by several famous chemists, including Antoine Lavoisier and Jöns Berzelius, to carry out distillation processes. Today, condensers have replaced retort flasks as a more convenient apparatus; nonetheless, retort flasks are still commercially available and can be used for non-complex distillation.
What is a beaker used for in chemistry?
Beakers are one of the most commonly used laboratory apparatus that one can come across in a chemistry lab. They are cylindrical, have a flat bottom, and a small spout on the top to pour chemicals. Beakers are usually made of borosilicate glass or plastic. While plastic beakers are only used to mix the chemicals, glass beakers have high thermal stability and can be used to heat chemicals also. Moreover, glass beakers provide more clarity for content visibility and measurement than their plastic counterparts. Beakers come in several sizes with volumes ranging from 5 milliliters to 10000 milliliters. Beakers are often used to hold, mix, and heat individual chemicals or chemical mixtures.
What is a watch glass?
A watch glass is a circular concave piece of glassware used in chemistry labs for a variety of applications. These include a surface to evaporate a liquid, to hold solids while weighing, to heat a small amount of substance, and as a beaker cover. This application is often employed to keep dust and other particles out of the beaker; however, the watch glass does not entirely seal the beaker, allowing gas exchanges to occur.
What is a separating funnel?
A separatory funnel, or separating funnel, is a piece of laboratory glassware used to separate two immiscible liquids with similar densities. It is a cone-shaped apparatus with a hemispherical head, a cylindrical tube outlet, and a Teflon stopper known as a stopcock. It comes in various sizes with volumes ranging from 30ml to 3Liters. It is well-known in organic chemistry for its application in the solvent extraction technique, commonly known as the liquid-liquid extraction technique. This technique is based on the concept of relative solubilities of chemical compounds. For instance, organic compounds like oils do not mix well with a polar solvent like water and can thus be separated using a separatory funnel. Water will settle in the separating funnel because it is denser than oil, while oil will float above it. Because the tap in a separating funnel has a thinner cross-section, the two layers are allowed to drip out individually, resulting in their separation.
What is the Kipp generator?
Kipp’s Apparatus, also known as Kipp’s generator, is a device used in the chemistry lab to prepare gases such as hydrogen sulfide gas, carbon dioxide gas, and hydrogen gas. It was invented around 1844 by the Dutch pharmacist, Petrus Jacobus Kipp. The device is usually made of glass or polyethylene and consists of three chambers that are layered one on top of the other. The liquid reagent is poured via the top chamber, which is connected to the bottom chamber through a tube that runs through the middle chamber. When the bottom chamber is completely filled, the middle chamber’s stopcock is opened for a brief moment to expel the air. The liquid reagent then rises to the middle chamber and reacts with the solid reagent to produce the necessary gas, which can then be drawn off through the stopcock.
What is a graduated cylinder?
A graduated cylinder, also known as a volumetric cylinder or measuring cylinder, is a long slender vessel used to measure the volume of liquids in the chemistry lab. They come in various sizes with volumes ranging from 5 mL to a few Liters. Large graduated cylinders are typically made of polypropylene because of its excellent chemical resistance or polymethylpentene because of its transparency, which makes them lighter and less fragile than glass. Graduated cylinders contain a strong base or foot for stability and a spout to enable pouring out the contents. Some glass cylinders contain a plastic bumper or ring to help prevent inadvertent breaking if the cylinder falls over due to its unsteadiness.
