Select Level 3 products for ultimate performance and sensitivity from your methods, while maintaining the highest levels of sample security and integrity. Choose from soft polyethylene caps with double snap functionality that guarantees a tight seal.

Pre-slit septa options are available for those who want septa that prevent vial-overfilling issues and re-seal well enough to avoid sample evaporation.
