Blue Screw Caps with Pre Slit
These 9mm blue screw caps with bonded pre-slit red and white PTFE/silicone septa offer a reliable and convenient solution for accessing container contents while maintaining a secure seal. The blue screw cap provides a tight, leak-proof closure, while the pre-slit septa allows for easy needle penetration for sampling or adding substances without the need for core removal. The bonded construction of the PTFE/silicone septa ensures durability and prevents the septa from falling out during use. The red and white layers offer easy visibility and confirmation of needle penetration depth. With a thickness of 1mm, these septa provide a robust barrier against contamination. These caps are ideal for a variety of applications, including chromatography, sample storage, and pharmaceutical packaging. They are compatible with standard 9mm vials and offer a secure and user-friendly solution for maintaining sample integrity.
