SecurityLINK HPLC/UHPLC Fingertight Fittings
Product Information
Brand
SecurityLink fingertight fitting system simplifies your system and column connections
To ensure that any HPLC or UHPLC system provides high efficiency and good peak shape it is essential to minimize dead-volume within the system. A common contributor to additional dead-volume are fitting connections routinely made to the column inlet and outlet which can lead to lower than expected efficiency, peak tailing, or misshaped peaks. SecurityLINK HPLC/UHPLC Fingertight Fittings provide a convenient solution with its auto-adjusting frit accommodating the precise depth of virtually every manufacturer’s column inlet to ensure a zero dead-volume connection. Additionally, the integrated Torque Limiting Technology eliminates column over- and undertightening that typically would result in column damage and poor analytical results.
- Better HPLC/UHPLC Results with Zero Dead-Volume Connections
- Torque Limiting Technology Prevents Overtightening and Undertightening
- Pressure Rated to 19,000 psi (1,310 bar)
Inside SecurityLINK Fingertight Connections
The SecurityLINK LC fingertight fitting system simplifies your system and column connections while providing consistent performance through Torque Limiting Technology that prevents column damaging overtightening.
The Dead-Volume Difference
SecurityLINK LC Fittings vs Conventional Fittings
Poorly connected fittings are often the causes of carryover, band broadening, and peak tailing. SecurityLINK offers zero dead-volume connections every time.

Improved Column Performance
Increased Peak Efficiency and Reduction in Peak Asymmetry
PEEKsilâ„¢ tubing is manufactured with extremely high levels of precision in terms of ID and is also machine cut to provide connections with minimal dwell volume. As such it has become the tubing of choice where connections close to zero dwell volume are required. When moving from a conventional PEEKsil nut and ferrule fitting system to a SecurityLINK PEEKsil LC fingertight fitting system an increase in peak efficiency, and a reduction in peak asymmetry was demonstrated.SecurityLINK PEEKsil UHPLC

Superior Robustness and Reproducibility
SecurityLINK Lifetime
While typical fittings are not cross-column compatible and prone to cause column damage with overtightening, SecurityLINK safely and easily allows you to continuously attach and detach columns. To illustrate the high robustness and durability of the SecurityLINK LC Fitting System, the fitting was disconnected and reconnected 100 times to a highly sensitive sub-2 μm core-shell UHPLC column.
