Test tube holder is an easy way to organize test tubes and prevent the test tubes from falling and breaking. It provides a safe way for you to store test tubes, especially when they are being used for ongoing experiments. It used to hold test tubes. It is used for holding a test tube in place when the tube is hot or should not be touch. Test tubes are widely used by chemists to handle chemicals, especially for qualitative experiments and assays. Test tube racks used to hold upright multiple test tubes at the same time. They are most commonly used when various different solutions are needed to work with simultaneously, for reasons, for safe storage of test tubes, and to ease the transport of multiple tubes. Evaporating Dishes are glassware containers used for laboratory testing. They are used for the evaporation of liquids and solutions to produce a solid substance or concentrated solutions. Dishes have a shallow flat round surface to promote evaporation. A test tube brush or spout brush is a brush used for cleaning test tubes and narrow mouth laboratory glassware, such as graduated cylinders, burettes, and Erlenmeyer flasks. Spatulas are used to transport and distribute dry chemical compounds. Spatulas are used most often when weighing out chemicals on a balance because they allow you to collect very small quantities of the chemical at a time. A water bath is a laboratory equipment that is used to incubate samples at a constant temperature over a long period of time. Water bath is a preferred heat source for heating flammable chemicals instead of an open flame to prevent ignition Distilling flasks, also known as distillation flasks, are types oflaboratory flask forming part of larger distillation assemblies used for the separation and/or purification of liquids or liquid mixtures where the components have different boiling points. Watch glasses are circular, slightly-concave pieces of glass that are used by chemists to evaporate liquids and cover beakers during sample preparation. They are also used to hold solids during weighing. A laboratory tripod is a three-legged platform used to support flasks and beakers. Tripods are usually made of stainless steel or aluminium and made light-weight for efficient portability within the lab. Often a wire gauze is placed on top of the tripod to provide a flat base for glassware. Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operatio Erlenmeyer flasks are used to contain liquids and for mixing, heating, cooling, incubation, filtration, storage, and other liquid-handling processes. An alcohol lamp is used for heating, sterilization, and combustion in a laboratory. The alcohol lamp uses ethyl alcohol or spirit as a fuel. It is generally made up of glass, brass or aluminum. Bunsen burner It is used to heat substances, to combust substances, and to sterilize objects on high heat. A graduated cylinder, also known as a measuring cylinder or mixing cylinder, is a common piece of laboratory equipment used to measure the volume of a liquid Wire gauze is an important piece of supporting equipment in a laboratory as glassware cannot be heated directly with the flame of a Bunsen burner, and requires the use of a wire gauze to diffuse the heat, helping to protect the glassware. Volumetric flasks are used for accurate dilutions and preparation of solutions and any other liquids needed at the laboratory workflow. Pasteur pipette or simply dropper, is a device used to transfer small quantities of liquids. They are used in the laboratory and also to dispense small amounts of liquid medicines. Iron ring is used to support flasks or funnels upright in a stand. This is to enable the stability of the flask or funnel while testing is being performed. A ring stand is used to provide support for other equipment and a means of raising equipment above the work surface. Iron stand supports the iron ring when heating substances or mixtures in a flask or beaker An iron clamp is a piece of laboratory equipment used to hold things and is placed in an iron stand to elevate other equipment. A condenser is a piece of laboratory equipment that is used to condense vapours in the lab or turn them into liquids simply by cooling them down. clay triangle is a piece of laboratory apparatus that is used to support a crucible being heated by a Bunsen burner or other heat source. It is made of wires strung in an equilateral triangle on which are strung hollow ceramic, normally fire clay, usually supported on a tripod or iron ring. A triangular file is used in the chemistry lab to score glass tubing to create clean breaks in the glass. Separatory funnels are used in the lab for liquidliquid extractions, separating a mixture's components into two solvent phases of different densities. The higher density liquid sinks to the bottom and can then be drained from a valve, leaving the less dense liquid in the funnel. A stirring rod is used for mixing liquids, or solids and liquids. Stir rods are used as part of proper laboratory technique when decanting supernatants because the contact helps to negate the adhesion between the side of the glassware and the supernatant that is responsible for the liquid running down the side. Rubber stoppers are ideal for plugging joints or holes in laboratory glassware and creating a liquid-tight seal. Rubber bungs are often used with glass containers such as test tubes, flasks, jugs, and many other pieces of standard lab equipment. It is used as a container to hold liquids. A Florence flask has a round body, a long neck, and often a flat bottom. It is designed for uniform heating, boiling, distillation and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use. Crucible tongs are welded steel mortar and pestle chemistry sets to crush up solid chemicals into smaller pieces, or to grind solids into fine powder. melting and heating. A crucible with cover is a type of laboratory glassware designed to melt or burn solid chemicals over a burner. Made from heat-resistant ceramic or metal, they'll withstand high temperatures up to 1050° Fahrenheit. tools used to lift a hot crucible from a furnace or for other items which cannot be handled with bare hands. also be used to prevent any inaccuracies. Funnels and filtration products are familiar items in the laboratory used for filtering, filling, decanting or transferring liquids or powders from one vessel to another. Laboratory funnels are made from glass, plastic (typically HDPE) or occasionally metal.
