Forensic and Clinical Applications
These premium certified tubes meet the stringent requirements of forensic DNA laboratories, clinical molecular diagnostics, and research applications where human DNA contamination must be eliminated. The locking cap design prevents accidental opening during sample transport, vortexing, and thermal cycling. The ATP-free certification ensures compatibility with bioluminescence-based contamination detection assays. Each lot ships with a Certificate of Analysis documenting purity testing results.
Enhanced Sample Security
The locking cap mechanism provides positive engagement that prevents inadvertent opening during high-speed centrifugation, incubation, or sample handling. This enhanced security is essential for chain-of-custody requirements in forensic applications and prevents sample loss or cross-contamination in busy clinical laboratories. The secure seal also minimizes evaporation during extended storage.
