Description
High-Performance Liquid Chromatography (HPLC) Plug manufactured from PEEK. These specialised end plugs are designed to securely seal the ends of HPLC columns, ensuring leak-free connections and maintaining optimal system performance:
Thread size: 10-32 UNF
Thread length: 0.39″ (10.00mm)
Material: PEEK 450G
Features: Integrated ferrule / Finger-tight fitting.
Finger Tightening:
The finger-tightening option allows this fitting to be manually tightened without the need for wrenches or other tools. This design features a knurled surface, which provides a better grip and allows the user to easily tighten the fitting by hand. These fittings are particularly advantageous in applications requiring frequent connection and disconnection, such as routine maintenance or changing columns.
No ferrules required
Ease of Installation: End plugs are simple to install as they do not require a separate ferrule. This reduces the number of components and steps involved in the sealing process, making it quicker and more user-friendly.
Reduced Risk of Leaks: By eliminating the need for a ferrule, these end plugs reduce the potential for improper ferrule seating, which can lead to leaks. The design ensures a reliable and consistent seal.
Manufactured in PEEK:
Chemical Resistance
Wide Range of Compatibility: PEEK exhibits excellent resistance to a broad spectrum of chemicals, including organic solvents, acids, and bases commonly used in HPLC. This ensures that the fittings do not degrade or react with the mobile phases or samples.
Non-Contaminating: Because PEEK is chemically inert, it does not leach contaminants into the mobile phase, which is crucial for maintaining the purity and integrity of the samples.
Mechanical Strength and Durability
High Pressure Resistance: HPLC systems often operate at high pressures. PEEK has the mechanical strength to withstand these pressures without deforming or failing.
Wear Resistance: PEEK fittings are durable and can endure the repeated connect and disconnect cycles typical in HPLC applications, ensuring a long service life.
Thermal Stability
Wide Temperature Range: PEEK retains its mechanical properties over a wide temperature range. This makes it suitable for HPLC systems that may experience varying temperatures during operation.
Consistency: The thermal stability of PEEK ensures that the fittings maintain a consistent seal and mechanical performance even under fluctuating temperature conditions.
Biocompatibility
Non-reactive: PEEK is biocompatible and does not interact with biological samples. This makes it an ideal material for HPLC applications in pharmaceuticals, biotechnology, and clinical research where sample integrity is critical.
Safe for Sensitive Applications: PEEK’s non-toxic nature makes it safe for use in applications involving sensitive or hazardous substances.
HPLC PEEK Plug direct applications:
Column Storage and Preservation:
Protecting Columns When Not in Use: PEEK end plugs are used to seal HPLC columns when they are not in use, preventing contamination and maintaining the integrity of the column’s packing material.
Transporting Columns: When HPLC columns need to be transported between locations, end plugs ensure that the columns are securely sealed, preventing any potential damage or contamination.
Preventing Contamination:
Unused Ports: In complex HPLC systems with multiple ports and pathways, PEEK end plugs are used to seal unused ports to prevent contamination and maintain system cleanliness.
Sample Integrity: By sealing off open ends, these plugs help preserve the integrity of samples and solvents within the system, which is crucial for accurate and reliable results.
Maintenance and Downtime:
System Maintenance: During maintenance or cleaning of the HPLC system, PEEK end plugs are used to seal components that are not being serviced, ensuring that the rest of the system remains uncontaminated.
Extended Downtime: If an HPLC system is not going to be used for an extended period, end plugs can be employed to protect the system from dust, moisture, and other contaminants.
Method Development and Testing:
Isolation of Components: In method development or troubleshooting, PEEK end plugs can be used to isolate specific components of the HPLC system for testing and optimization.
Calibration and Validation: During calibration and validation procedures, certain parts of the system may need to be temporarily sealed off to ensure accurate and precise measurements.
