HPLC PEEK Bulkhead Union (for 1/16" OD Tubing) conform to the following Standards/Norms:

The HPLC Bulkhead Union made of PEEK (Polyetheretherketone) is a specialised component designed for 1/16" capillary tubes in High-Performance Liquid Chromatography (HPLC) systems. This unique through-wall fitting allows for a convenient and tool-free connection on either end through a bulkhead, providing a secure and leak-free joint between the capillary tube and the HPLC system. 

Thread size: #3/8-24 UNF, #10-32 UNF

Thread length: 0.55” (14mm)

Material: PEEK

Features: Choice of fitting / compatible with flanged tubing.

Choice of fitting:

Compatibility with Different Systems:

Versatility in Application: Different thread sizes allow the bulkhead union to be used in a wider range of systems and setups, accommodating various equipment and tubing configurations.

Compatibility with Existing Systems: Laboratories often have equipment with different thread standards. Offering multiple thread sizes ensures compatibility with existing hardware, reducing the need for additional adapters or modifications.

Compatible with flanged tubing:

Enhanced Sealing Capability: Flanged tubing provides a larger sealing surface area, which improves the connection's integrity and reduces the risk of leaks. This ensures more reliable and accurate chromatographic results.

Increased Stability: The flange on the tubing helps secure it more firmly within the bulkhead union, reducing the likelihood of disconnection or movement under high-pressure conditions typical in HPLC systems.

Manufactured in PEEK:

Chemical Resistance: PEEK is highly resistant to a wide range of chemicals and solvents commonly used in HPLC, including acids, bases, and organic solvents. This ensures that the bulkhead union does not degrade or contaminate samples, maintaining the integrity of the chromatographic system.

High Temperature Stability: PEEK can withstand high temperatures without deforming or losing its mechanical properties, making it suitable for use in HPLC systems that may operate at elevated temperatures.

Mechanical Strength: PEEK has excellent mechanical properties, including high tensile strength and toughness. This ensures that the bulkhead union can withstand the high pressures often encountered in HPLC systems without failure.

Low Extractables: PEEK has low levels of extractables, which means it does not leach impurities into the mobile phase or samples. This is critical for maintaining the purity and accuracy of chromatographic analyses.

Biocompatibility: PEEK is biocompatible, making it suitable for use in applications involving biological samples or pharmaceutical products. It does not interact with or alter the biological properties of samples.

Durability: PEEK is highly durable and resistant to wear and abrasion, which extends the lifespan of the bulkhead union and reduces the need for frequent replacements.

Inertness: PEEK is inert and does not react with most chemicals, ensuring that it does not interfere with the analytical process or the compounds being analyzed.

Flexibility: PEEK's flexibility allows for easy installation and alignment of tubing, ensuring secure and leak-free connections.

Lightweight: PEEK is lighter than metals, reducing the overall weight of the HPLC system and making it easier to handle and install components.

Consistency and Reproducibility: The use of PEEK ensures consistent performance and reproducibility in HPLC analyses, as it maintains its properties over time and under varying conditions.

Regulatory Compliance: PEEK often meets regulatory standards for materials used in analytical instruments, ensuring that it can be used in regulated industries such as pharmaceuticals and biotechnology.

HPLC PEEK Bulkhead Union applications:

Pharmaceutical Analysis: Used to ensure secure and reliable connections in systems analyzing drug compounds and formulations.

Environmental Testing: Suitable for analyzing pollutants and contaminants in water and soil samples.

Food and Beverage Testing: Ensures contamination-free analysis of food additives, contaminants, and quality control measures.

Clinical Diagnostics: Reliable for use in systems analyzing biological samples for clinical research and diagnostics.

Biotechnology Research: Used in systems requiring sterile and inert components for protein and nucleic acid analysis.

Material Science: Suitable for analyzing the chemical properties of materials and polymers.

Petrochemical Analysis: Used in high-pressure systems analyzing complex hydrocarbon mixtures.
