The kit contains 10 screw/barb swivel connectors (1/4-28″, barb 1/16″) and 2 m of Tygon tube (1/8″ OD 1/16″ ID). All the components of the kit are autoclavable and therefore, can be reused. Swivel connectors are easy to use and eliminate the twist and entanglement of flexible tubing during connection. Tygon is a largely non-reactive material and thus, is one of the preferred materials for biomedical applications.
