3） Key Features
- Designed exclusively for 20/40/60 mL vials with standard 24-400 screw thread
- PP cap paired with firmly fitted PTFE/silicone composite septa; outstanding chemical resistance and repeatable resealing performance.
- Silicone provides superior tight sealing while PTFE offers powerful anti-corrosion capacity
- Both caps and septa liners are reusable, washable, heat-tolerant and autoclavable to meet diverse experimental requirements
4) Applications
24-400 PP caps with septa are extensively applied in chemistry, bioscience and medical research, especially for long-term liquid sample storage and shipment.
They perfectly match GC & HPLC sample vials, and are also widely deployed in environmental monitoring, clinical diagnosis and food safety testing.
Excellent sealing capability effectively avoids loss of volatile organic compounds (VOCs), securing accurate and consistent analytical results. Featuring great resistance to high and low temperatures, these caps work perfectly for experiments requiring thermal treatment or frozen sample preservation.
