Laboratory Equipment. This generally refers to the various tools and equipment used by scientists and technicians working in a laboratory; equipment used to perform experiments, take measurements, or gather data. These include tools such as Bunsen burners, and microscopes, laboratory glassware, as well as high-end specialty equipment such as conditioning chambers, spectrophotometers, calorimeters, autoclaves, etc.

Lab Case Work

Laboratory Casework. Laboratory casework includes base cabinets, wall cabinets, and storage and supply cabinets, and desks. Items that complement casework include and may include fume hoods, countertops, sinks, plumbing fixtures, and a robust wiring service with an abundance of electrical outlets. Modern laboratory casework is modular, allow it it to be customized and rearranged to fit the laboratory’s changing needs. Casework is made from several different materials: wood, plastic laminate, and metal. Stainless steel is a good choice for areas subject to high moisture, frequent cleaning, heavy abrasion, and abuse. Good casework has a smooth, chemically resistant, and easily cleaned surface with the durability to stand up to strong chemicals and abrasion.

Piping Labels. Paper or plastic self-stick labels marked with information to indicate what a pipe is transporting, in which direction, and safety advisories. Many labels, for common conditions, are available pre-printed. For special applications, label printing machines may be used. Labeling could also include metal valve identifiers that are attached using wire twists, and lock-out/tag-out tags.

Laminar Flow Hoods

Laminar Flow Hood: A laminar flow hood, or cabinet, is a carefully enclosed workbench designed to prevent contamination of particle-sensitive devices such as semiconductor wafers and biological samples. Air is drawn through a filter and blown in a smooth, laminar flow towards the user. Hoods are manufactured in both horizontal and vertical configurations in a variety of airflow patterns. Some have a germicidal lamp to sterilize the shell and contents when not in use.

Glass Lined Piping: Glass lining is a form of porcelain enamel, much like the material applied to tubs and sinks for many years. It is applied in a process that forms a permanent chemical and physical bond with the metal surface. The finished surface is extremely smooth and very hard, making glass-lined pipe ideal for transfer of solids or chemicals that tend to adhere to the inside of bare pipe. Using glass-lined pipe significantly reduces maintenance, wasted energy, and repair costs associated with solids build up in piping systems. It is non-permeable; resistant to corrosion, abrasion, high temperatures, and thermal shock; and has a wide pH range

Liquid Ring

Liquid Ring Vacuum Pump: A rotating positive displacement pump. Its function is similar to a rotary vane pump except that the vanes are part of the rotor and churn a rotating ring of liquid to form the compression chamber seal. Because the rotor is the only moving part, they generate low friction. These pumps are typically powered by an induction motor. The liquid ring pump compresses gas by rotating a vaned impeller within, and eccentric to, a cylindrical casing.

Low Temperature Chillers

Biopharmaceutical Low Temperature Chillers: A precision machine that removes heat from a liquid using a vapor-compression or absorption refrigeration cycle. In their industrial application, cooled water or other liquid from the chiller is pumped through process or laboratory equipment. They are used for controlled cooling of products, mechanisms, and machinery. They are often used in chemical processing and pharmaceutical formulation. They are typically closed-loop systems. They recirculate a clean coolant or clean water at a constant temperature and pressure to increase the stability and reproducibility of water-cooled machines and instruments. Most industrial chillers use refrigeration as the media for cooling, but some rely on simpler techniques such as air or water flowing over coils.

Lyophilizers: Equipment used to preserve perishable materials by freeze drying. Freeze drying (lyophilization) is a dehydration process that freezes materials, reduces surrounding pressure, and adds heat to allow frozen water in the material to change from the solid phase to gas.
