Reliable Sealing for Chromatography ApplicationsEnsure the integrity of your analytical samples with these aluminum crimp caps paired with pre-slit PTFE/silicone septa, which deliver a chemically stable, tight seal for standard 11 mm autosampler vials. Specifically designed for use in HPLC and GC workflows, these caps help prevent sample evaporation and contamination during storage and analysis.
Durable and Flexible for Modern LaboratoriesConstructed from robust aluminum and high-grade PTFE/silicone, these caps withstand a broad temperature range and are compatible with autoclaving for enhanced versatility. Their universal fit and high tolerance to chemicals make them suitable for a variety of autosamplers, and they can be easily integrated into both manual and automated crimping processes.
FAQ's of Waters Corp Aluminum Crimp Cap and PTFE/Silicone Septum, 100/pk:
Q: How should the Waters Aluminum Crimp Cap with PTFE/Silicone Septum be used with chromatography vials?
A: Simply position the cap with its pre-slit PTFE/silicone septum over an 11 mm crimp neck vial and secure it using a manual or automated crimper. This ensures a leak-proof seal for storing samples prior to chromatographic analysis.
Q: What makes the PTFE/silicone septum suitable for analytical applications?
A: The septum features a high-quality PTFE layer laminated to silicone, providing chemical inertness and minimizing risk of sample interaction or contamination. Its 1 mm thickness ensures durability and reliable resealability after needle puncture during autosampler operations.
Q: When should these crimp caps and septa be autoclaved?
A: Although supplied non-sterile, these caps and septa can be autoclaved when sterile conditions are required for sensitive applications, ensuring versatility in laboratory workflows.
Q: Where can these caps and septa be used in laboratory processes?
A: They are ideal for sealing vials in laboratories performing HPLC and GC analysis, and are compatible with Waters and most standard autosamplers, making them suitable for a wide range of analytical laboratories.
Q: What is the process for ensuring a tight and secure seal?
A: After placing the crimp cap and septum on the vial, use the appropriate crimping tool-manual or automated-to crimp the cap evenly. This enables an airtight and evaporation-resistant seal, crucial for maintaining sample integrity.
Q: What are the key benefits of using these aluminum crimp caps with PTFE/silicone septa?
A: They offer a chemically inert, reliable seal that prevents sample loss and contamination, handle a wide temperature range, and allow repeated needle penetrations for sample injection or extraction without compromising integrity.
