VacuTight Fittings are designed to provide airtight, dependable connections under vacuum and low pressure conditions. Many of the VacuTight Nuts have streamlined profiles for use in systems requiring a large number of connections in a small area. Furthermore, the VacuTight Ferrule’s small size ensures sufficient nut/thread engagement, even in shallow ports. These features make VacuTight Fittings ideal for “combichem” high throughput screening, clinical diagnostic, and other automated
liquid handling applications.
The configuration of the VacuTight flat-bottom ferrules prevents overcompression and tubing ID reduction that can occur with many coned fittings. The result is more consistent aspirating and dispensing volumes across all system connections. The VacuTight fittings can also work well in some positive pressure applications.
The pressure range for each fitting is listed below and depends upon the tubing used for the connection.
Please note that some of the VacuTight fittings have changed in color from red to black; however, this color change does not affect product performance. All VacuTight Nuts must be used exclusively with VacuTight Ferrules.
