SeptaSecure Products
SeptaSecure® Centrifuge Tubes and Septa Caps
SeptaSecure® products allow needle or pipette access to samples without cap removal. Available as complete centrifuge tube assemblies or caps only in uncut or cross-cut configurations.
Why Septa Caps
Traditional centrifuge tubes require cap removal for sampling, exposing samples to air and potential contamination. Septa caps allow needle or pipette access while maintaining a closed system—preventing sample volatilization, reducing crosscontamination risk, and enabling automated workflows where tubes remain sealed throughout multi-step processes.
Product Categories
Centrifuge Tubes with Septa Caps
Complete tube assemblies in Type-F* and Jet formats. Available in 15mL and 50mL sizes with uncut or cross-cut septa configurations.
Septa Caps Only
Caps for centrifuge tubes. Jet caps are available in 15mL and 50mL sizes. Type-F* caps available in 50mL size. Both are offered in uncut or cross-cut configurations.
Septa Configurations
Uncut silicone septa: Solid membrane for needle access in automated sampling systems. Maintains a closed system during robotic liquid handling.
Cross-cut silicone septa: Pre-cut membrane for pipette access without cap removal. Reduces sample exposure during manual sampling.
Product Formats
Type-F:* SeptaSecure® products using Falcon® centrifuge tubes—an industry-standard format preferred by laboratories requiring established tube specifications.
Jet: SeptaSecure® products using conical centrifuge tubes in standard 15mL and 50mL formats. Same septa cap technology as Type-F.
Note: Jet caps are designed for SeptaSecure® Jet tubes. Type-F caps are designed for Falcon® centrifuge tubes. Compatibility with other manufacturers' tubes may vary due to threading specifications.
Applications
Originally developed for water quality analysis, SeptaSecure® products are used in robotic sample preparation, pharmaceutical research, clinical diagnostics, and environmental testing where contamination-resistant sample handling is required.
