HPLC Fittings, Connectors & Fluidic Accessories

HPLC fittings, connectors, and fluidic accessories are essential components used to assemble, adapt, and maintain low‑dead‑volume flow paths in liquid chromatography systems. This category includes nuts, ferrules, unions, adapters, column connectors, and related fluidic components designed to support secure, reliable connections in HPLC and UHPLC systems.

These components are used throughout chromatography systems—from solvent delivery and injection to column connections and detection—where precision, chemical compatibility, and mechanical reliability are critical.

Applications & System Integration

Fluidic components in this category are used to:

• Establish leak‑free, low‑dead‑volume connections

• Adapt tubing sizes and materials

• Connect columns, valves, injectors, and detectors

• Maintain consistent flow paths under high and low pressure

• Support both analytical laboratories and OEM system designs

Proper selection and integration of fluidic fittings is essential for system performance, reproducibility, and long‑term reliability.

Component Categories

This category includes:

• HPLC column connectors, including direct‑adaptive (Di‑Ad™) designs engineered with universal pilot lengths for compatibility across column brands

• Nuts and ferrules for high‑ and low‑pressure tubing connections, available for common tubing outer diameters

• Unions & Adapters - Connectors - MICROSOLV Technology Corporation

• Tubing connectors, supporting both stainless steel and polymer‑based fluidic systems

• Sample loops, compatible with a variety of injector designs and instrument platforms

• Column hardware and packing components, including PEEK‑based options for bio‑compatible and medium‑ to high‑pressure applications

These components are designed to support modular system assembly and customization.

Materials & Manufacturing Considerations

Fluidic fittings and connectors are offered in:

• Stainless steel, for high‑pressure and chemically demanding environments

• PEEK and other polymer materials, supporting bio‑inert and metal‑free systems

Many components in this category are manufactured or produced to specification under the ARE‑Applied Research™ brand, supporting consistent quality, dimensional control, and scalability for both laboratory and OEM use.

OEM & System‑Level Use

In addition to laboratory use, these components are commonly specified by:

• Instrument manufacturers

• OEM system integrators

• Engineering teams designing fluidic subsystems

The breadth and consistency of this product family make it suitable for standardized builds, private‑label programs, and custom configurations.
