Superior Protection Against Backflow

The antidiffusion valve's unidirectional flow mechanism prevents reagents from diffusing backward into the liquid chromatography or titration system. This design safeguards sample integrity and accuracy, especially in sensitive analytical applications. Its robust construction and reliable operation make it essential for consistent performance in your laboratory's workflow.

Exceptional Compatibility and Versatility

Engineered for seamless integration, this valve pairs perfectly with Metrohm ion chromatography, titration instruments, and sample handling modules. Its standard fittings and chemical-resistant material ensure flexibility across diverse applications in research, quality control, and routine lab analysis. The individually packed, sterile format further streamlines installation and maintains a contamination-free environment.

FAQ's of Metrohm Antidiffusion valve:

Q: How does the Metrohm Antidiffusion Valve prevent backflow in liquid chromatography systems?

A: The valve utilizes a unidirectional mechanism that automatically closes under back pressure, ensuring reagents and solvents only move in the intended direction, thus preventing diffusion and backflow in liquid chromatography and titration systems.

Q: What chemicals is the antidiffusion valve compatible with?

A: Constructed from PTFE and other chemical-resistant polymers, the valve boasts excellent resistance and can be safely used with strong acids, bases, and a wide range of organic solvents found in analytical laboratories.

Q: When should I use the Metrohm Antidiffusion Valve in my laboratory setup?

A: This valve is essential whenever there is a risk of reagent diffusion or cross-contamination in Metrohm ion chromatography, titration, or sample handling systems, especially when dealing with sensitive compounds or maintaining sample purity is critical.

Q: Where in the flow path should the antidiffusion valve be installed?

A: Install the valve along the capillary between the reagent reservoir and the analysis instrument, ensuring the flow direction matches the arrow on the valve body for optimal unidirectional flow and prevention of back-diffusion.

Q: What is the process for sterilizing the valve for sensitive applications?

A: The antidiffusion valve can be autoclaved. Simply place the individually packed valve in an autoclave and follow your laboratory's standard sterilization procedure for PTFE and polymeric components to ensure hygienic, contamination-free installation.

Q: How does the valve benefit my analytical results?

A: By blocking unwanted backflow and preventing cross-contamination between reagents, the valve maintains the integrity and accuracy of your ion chromatography and titration results, leading to more reliable and reproducible data.

Q: Is the Metrohm Antidiffusion Valve compatible with standard analytical flow rates and what are its typical operating limits?

A: Yes, it is suitable for flow rates up to 10 mL/min and operates reliably within a pressure resistance of up to 6 bar (87 psi) and temperature range of 5C to 50C, making it ideal for standard Metrohm analytical workflows.
