Precision Fittings for Optimal HPLC/UHPLC Performance

Minimize Dead Volume. Maximize Analytical Precision.

Achieving high chromatographic efficiency and ideal peak shape requires eliminating sources of dead volume throughout the HPLC/UHPLC flow path—particularly at the column inlet and outlet. Improperly tightened fittings are a common contributor to added dead volume, often resulting in decreased column efficiency, peak tailing, and distorted peak profiles.

SecurityLINK™ and SecurityLINK™ ET fittings are engineered to address this issue through integrated or external torque-limiting technology. These fittings ensure consistent, optimal torque is applied during connection, effectively eliminating variability due to under- or over-tightening. This reduces the risk of column damage, improves reproducibility, and maintains system integrity under high-pressure conditions.

Technical Features & Benefits

• Zero Dead-Volume Connections
  Optimized internal geometries and precise torque application eliminate excess voids at column connections, preserving chromatographic performance.

• Torque-Limiting Technology
  Built-in (SecurityLINK) or external (SecurityLINK ET) mechanisms provide controlled, repeatable tightening force to prevent overtightening and under-tightening.

• High Pressure Rating
  Certified for use at pressures up to 19,000 psi (1,310 bar), supporting even the most demanding UHPLC applications.

• Material Compatibility
  Constructed from materials compatible with a wide range of solvents and mobile phases used in LC analyses.
