Upchurch Scientific® MicroTight™ Unions manufactured by IDEX Health & Science provide an excellent opportunity to connect smaller, capillary tubing used in many of the more advanced analytical instruments today.

• Several configurations available
• Conductive versions
• Extremely low internal volumes

Several configurations are available to facilitate a variety of connections with 360 µm OD tubing and 1/32 in (0.8 mm) OD tubing, as well as options to connect a variety of "in-between" sizes using the MicroTight tubing sleeves

The Upchurch Scientific® Very High Pressure (VHP) Unions for Capillary Tubing from IDEX Health & Science allow convenient unions between 1/32 in OD tubing or 360 µm OD tubing. Each Union features a stainless steel union body and a unique stainless steel union capsule that enable excellent chemical compatibility and conductivity, making these a great choice for electrical interfacing in certain LC-MS applications. Each Union is coupled with direct-connect ferrules made from a proprietary PEEK™ polymer blend (PK) that allows tubing connections up to 15,000 psi (1,034 bar).

Conductive versions of these connectors allow the introduction of voltage into an electrospray or capillary electrophoresis system. With extremely low internal volumes, these unions can be used in even the most sensitive of applications. (Mount and apply voltage to the conductive versions of these connectors using the Upchurch Scientific Insulating Mounting Bracket, M-447).
