Tubing

Tubing is available in a variety of materials, sizes, and configurations, each designed for a specific application within the laboratory. Tubing choice depends on key criteria such as the nature of the fluid or gas being transferred, temperatures, pressure conditions, chemical compatibility, and the specific type of equipment being used. Consult tubing manufacturer guidelines and safety protocols to ensure that the appropriate tubing is selected. To support procedures using tubing, the appropriate connectors and fittings, tubing kits, and tubing tools are available.

Vacuum Tubing consisting of various plastics and rubber materials is used to connect laboratory equipment to vacuum pumps or aspirators, and is essential for processes like rotary evaporation, filtration, and drying under reduced pressure.

Plastic Tubing such as polyethylene, PTFE (Teflon™), PVC, and Tygon™ are known for their chemical resistance and are suited for transferring liquids, chemicals, and gases. Specific tubing types provide additional properties for handling. PTFE/Teflon™ tubing is ideal for high temperatures and aggressive chemicals; while Tygon™ tubing is suited for transfer of sensitive fluids as well as corrosive materials. All are for use with peristaltic pumps.

Rubber and Silicone Tubing consist of natural or synthetic rubber (silicone) and offer specific characteristics. Natural rubber is flexible and can be used in various applications such as connecting glassware, transferring liquids or gases, and providing airtight seals. Synthetic, rubber-like silicone is biocompatible and can withstand high temperatures—which makes it ideal for pharmaceuticals, medical devices, food processing, and more. It is also used with peristaltic pumps—especially for accurate and sterile fluid transfer.

Glass Tubing made of borosilicate is often used in lab setups for transferring liquids, gases, or chemicals found in distillation, fractionation, and other processes where high heat and chemical resistance is needed.
