Agilent InfinityLab UHPLC Fittings

Quick connect fitting

Agilent InfinityLab Quick Turn and Quick Connect UHPLC fittings deliver fast, reliable, zero-dead-volume connections for high-pressure liquid chromatography systems. Engineered for ease of use and consistent performance, these fittings simplify capillary connections while maintaining exceptional sealing integrity—even under demanding UHPLC conditions.

  • Quick Connect UHPLC fittings provide true finger-tight connections up to 1300 bar, enabling rapid setup without tools.
  • Quick Turn UHPLC fittings are ideal for hard-to-reach ports, offering finger-tight operation up to 400 bar and wrench-assisted sealing up to 1300 bar.

Both fitting families feature Agilent’s proprietary spring-loaded design to ensure zero dead volume, secure sealing, and repeatable performance across multiple reconnects. Designed for reuse with different capillaries, InfinityLab fittings help reduce downtime, minimize leaks, and support consistent chromatographic results.

Chrom Tech offers a broad selection of Agilent InfinityLab Quick Turn and Quick Connect fittings, with many of the most common configurations in stock and ready to ship—making it easy to streamline your UHPLC workflow with confidence.

Key Definitions â–¸
Quick Connect UHPLC Fittings
Tool-free UHPLC fittings designed for finger-tight connections up to 1300 bar, enabling rapid setup while maintaining zero-dead-volume sealing performance.
Quick Turn UHPLC Fittings
Compact UHPLC fittings engineered for tight or hard-to-access instrument ports, providing finger-tight operation up to 400 bar and wrench-assisted sealing up to 1300 bar.
Spring-Loaded Design
Agilent’s proprietary internal mechanism that automatically compensates for minor variations in capillary length, ensuring consistent zero-dead-volume connections across repeated installations.
Zero Dead Volume
A connection geometry that minimizes void space between capillary and fitting, reducing peak broadening, carryover, and signal loss in UHPLC workflows.
UHPLC (Ultra-High Performance Liquid Chromatography)
A high-pressure liquid chromatography technique operating at elevated pressures to achieve faster separations, improved resolution, and enhanced analytical sensitivity compared to traditional HPLC.
Frequently Asked Questions â–¸
What is the difference between Quick Connect and Quick Turn fittings?
Quick Connect fittings provide true finger-tight installation up to 1300 bar for fast, tool-free connections. Quick Turn fittings are designed for tight instrument spaces, offering finger-tight sealing up to 400 bar and wrench-assisted operation up to 1300 bar when higher pressure is required.
Do these fittings provide zero dead volume connections?
Yes. Both InfinityLab Quick Turn and Quick Connect fittings use Agilent’s spring-loaded design to maintain zero dead volume, helping preserve peak shape, reduce carryover, and improve chromatographic reproducibility.
Can InfinityLab fittings be reused with different capillaries?
Yes. These fittings are designed for repeated use with multiple capillaries without loss of performance, making them ideal for method development and routine system maintenance.
Are tools required to install InfinityLab Quick Connect fittings?
No tools are needed for Quick Connect fittings—they are finger-tight up to 1300 bar. Quick Turn fittings can be installed finger-tight up to 400 bar, with a wrench used only when higher pressure sealing is required.
Which applications benefit most from InfinityLab UHPLC fittings?
These fittings are well suited for UHPLC workflows in pharmaceutical, environmental, food safety, and life science laboratories where high-pressure reliability, minimal dead volume, and fast connection times are critical.
