CLEARLock® microcentrifuge tubes combine the security of a screw cap with the convenience of a snap cap, ensuring maximum sample protection during centrifugation and storage, ensuring enhanced sample protection during centrifugation, handling, and storage.
Manufactured from high-quality, medical-grade polypropylene, they provide excellent mechanical resistance and reliable sealing, even under high-speed conditions.
CLEARLine® versions are certified free from DNase, RNase, human DNA, ATP, pyrogens, and PCR inhibitors, making them ideal for contamination-sensitive applications in molecular biology and advanced laboratory workflows.
CLEARLock® CLEARLine® microtubes are engineered to provide superior sample protection in demanding laboratory applications. By combining a secure locking system with the ease of a snap cap, they prevent accidental opening and ensure reliable sealing during centrifugation and storage.
Manufactured from premium-quality virgin, medical-grade PP/PE, and free from biocides, plasticizers, and latex. Produced with optimized, high-gloss polished moulds, without incorporating slip additives such as oleamide, erucamide, or stearamide.
Designed to withstand centrifugation forces up to 30,000 x g without rupture, these microtubes preserve sample integrity even under extreme conditions. The hinged lid prevents unintentional opening, while the tight sealing minimizes evaporation during long-term storage or incubation.
Produced in controlled environments and batch-certified by independent laboratories, CLEARLine® microtubes guarantee the highest level of purity, being free from human DNA, DNase, RNase, ATP, pyrogens and PCR inhibitors.
Available in multiple volumes, including 5 ml formats for intermediate sample volumes, they represent a practical alternative to 15 ml tubes, reducing plastic waste and storage space requirements.
