Versatile Design for Laboratory SealingThese aluminium headspace caps offer universal compatibility with standard 20mm vials, ensuring suitability for a wide range of laboratory and chemical analysis applications. Their crimp-type and tamper-evident features enhance security during sample handling, while the anodized surface ensures durability.
Optimized for Manual and Automated ProcessesThe closure is engineered for compatibility with both hand-operated and automated crimpers and decrimpers, making it ideal for laboratories of all sizes. The smooth, anodized finish promotes easy application and removal while maintaining a secure seal.
Superior Material and Temperature ResistanceManufactured from anodized aluminium, these caps withstand temperatures up to 200C, making them suitable for demanding analytical procedures, such as GC and HPLC. Optional PTFE/Silicone liners provide enhanced chemical resistance and prevent sample contamination.
FAQ's of 20mm Aluminium Head space caps:
Q: How do I apply the 20mm aluminium headspace cap to a vial?
A: The cap is designed for crimping onto standard 20mm headspace vials using a compatible crimper. You can use either a manual or automated crimping tool for secure closure.
Q: What are the benefits of choosing a silver anodized aluminium cap with a PTFE/Silicone liner?
A: The anodized finish enhances durability and chemical resistance, while the optional PTFE/Silicone liner provides excellent sealing, reduces the risk of sample contamination, and supports a wider range of analytical applications.
Q: When should I opt for the sterile version of this headspace cap?
A: Sterile options are recommended for applications where sample purity or aseptic conditions are essential, such as in microbiological or pharmaceutical analysis. Non-sterile caps suffice for routine chemical or environmental testing.
Q: Where can these caps be used in laboratory settings?
A: These caps are suitable for use in headspace analysis, volatile organic compound (VOC) detection, gas chromatography (GC), and high-performance liquid chromatography (HPLC) sample preparation across research, environmental, and industrial laboratories.
Q: What is the process for ordering and packaging the 20mm aluminium headspace caps?
A: Caps are supplied with a minimum order quantity of 1,000 units, and are packed in polybags within sturdy cartons to ensure they remain protected during transit and storage. Contact a distributor, manufacturer, or supplier in India to place your order.
Q: Are these caps compatible with all standard 20mm headspace vials and crimping equipment?
A: Yes, these aluminium caps are designed to fit standard 20mm vials and are suitable for use with both manual and automated crimping and decrimping equipment.
Q: What advantages do tamper-evident features offer for laboratory sample security?
A: Tamper-evident features help ensure the integrity of your samples by providing visible evidence if a cap has been removed or altered, which is vital for quality control and chain of custody in analytical testing.
