![]() It can handle heat exposure up to 350 ☏ (177 ☌), beyond this temperature Epoxy Resin is used. The most common and durable type of material used is phenolic resin because they are lightweight, strong, chemical and moisture resistant. They are also often made of different materials depending on their usage. The laboratory countertops' styles and variations may differ according to where they are (geographical location) and what labs they are being used for. Materials such as lab notebooks, pencils, extra papers and folders are advised and expected to be stored away in the provided spaces or inside the drawer. Many laboratory countertops are equipped with drawers that can be used to store materials that might get in the way while conducting an experiment. Depending on the objectives of a lab, they may additionally be required to be resistant to acids or high temperatures. Common characteristics of preferred laboratory countertops are ones that are strong, durable, and water-, moisture- or chemical resistant. The purpose of the countertop would be different depending on whether it is used in a chemistry lab, physics lab, food science lab, microbiology or a biology lab. Characteristics of laboratory countertops are generally determined according to what reagents or corrosive chemicals are being used. They can be used to place equipments, tools, projects and chemicals. Laboratory countertops are countertops used specifically in science fields for educational labs or research purposes. They are often conformed to accommodate the installation of sinks, stoves (cookers), ranges, and cooktops, or other accessories such as dispensers, integrated drain boards, and cutting boards. The horizontal surface and vertical edges of the countertop can be decorated in manners ranging from plain to very elaborate. Kitchen countertops may also be installed on freestanding islands, dining areas or bars, desk and table tops, and other specialized task areas as before, they may incorporate cantilevers, freespans and overhangs depending on application. They may include an integrated or applied backsplash (UK: upstand) to prevent spills and objects from falling behind the cabinets. Finished heights from the floor will vary depending on usage but typically will be 35–36 in (890–910 mm), with a material thickness depending on that chosen. In the UK the standard width is 600 mm (approximately 24 inches). It can also act as kick space that may not have been provided at the floor, allowing a person to stand closer to the countertop, improving ergonomics. This allows for a convenient reach to objects at the back of the countertop while protecting the base cabinet faces. When installed in a kitchen on standard (U.S) wall-mounted base unit cabinets, countertops are typically about 25–26 inches (640–660 millimetres) from front to back and are designed with a slight overhang on the front (leading) edge. Primary considerations of material choice and conformation are durability, functionality, hygienics, appearance, and cost. The "unfitted" kitchen design style exemplified by Johnny Grey may also include detached and/or varied countertop surfaces mounted on discrete base support structures. The common fitted Western-style kitchen, developed in the early 20th century, is typically an arrangement of assembled unit cabinetry covered with a more-or-less continuous countertop work surface. In other contexts, the term bench benchtop, or “sink table” is used. In Australian and British English, the term counter is generally reserved for a surface of this type that forms a boundary between a space for public access and a space for workers to carry out service tasks. A countertop may be constructed of various materials with different attributes of functionality, durability and aesthetics, and may have built-in appliances, or accessory items relative to the intended application. The surface is frequently installed upon and supported by cabinets, positioned at an ergonomic height for the user and the particular task for which it is designed. ![]() They are built for work in kitchens or other food preparation areas, bathrooms or lavatories, and workrooms in general. ![]() A countertop, also counter top, counter, benchtop, worktop ( British English) or kitchen bench ( Australian or New Zealand English), bunker ( Scottish English) is a raised, firm, flat, and horizontal surface.
