Valco Syringe Adapters

Valco syringe adapters provide reliable manual sample introduction into chromatography systems by enabling direct syringe connections to valves and zero-dead-volume fittings. These precision components support consistent loading and controlled fluid transfer in analytical workflows.

Fill ports allow manual loading of sample injectors using 22-gauge syringes (26-gauge for 1/32" fill ports). The fill ports listed are designed specifically for use with metal valves, ensuring secure engagement and leak-resistant operation.

Female luer adapters provide direct syringe connections to zero-dead-volume fittings and valves, eliminating intermediate tubing while helping maintain low system volume and accurate sample delivery.

Key Definitions â–¶
Syringe Adapter
A fitting that enables direct syringe connection to valves or zero-dead-volume fittings for manual sample introduction.
Fill Port
A port designed for manual loading of sample injectors using syringes, commonly paired with metal valves in chromatography systems.
Female Luer Adapter
An adapter that provides direct syringe attachment to valves or fittings using standard luer connections.
Zero Dead Volume (ZDV)
A connection design that minimizes void spaces between components, helping preserve sample integrity and chromatographic efficiency.
Gauge (Needle Gauge)
A measurement of needle diameter. Valco fill ports typically use 22-gauge syringes, or 26-gauge syringes for 1/32" fill ports.
Metal Valve
A chromatography valve constructed from metal materials, designed to withstand higher pressures and compatible with Valco fill ports.
Frequently Asked Questions â–¶
What are Valco syringe adapters used for?
Valco syringe adapters allow manual sample loading by providing direct syringe connections to valves and zero-dead-volume fittings in chromatography systems.
What syringe sizes are compatible with Valco fill ports?
Valco fill ports typically accept 22-gauge syringes, while 1/32" fill ports use 26-gauge syringes for proper fit and sealing.
Can Valco syringe adapters be used with any valve?
Fill ports listed for Valco syringe adapters are intended for use with metal valves. Female luer adapters provide broader compatibility with zero-dead-volume fittings and valves.
What is the benefit of female luer adapters?
Female luer adapters allow direct syringe attachment to valves or fittings, eliminating intermediate tubing and helping maintain low system volume during manual sample introduction.
Are Valco syringe adapters suitable for HPLC systems?
Yes. Valco syringe adapters are commonly used in HPLC and analytical systems for controlled manual sample loading when properly installed.
