Diamond™ PosiStop LTS-Compatible Pipette Tips Diamond PosiStop LTS-compatible pipette tips help improve laboratory accuracies by ensuring a positive seal between pipettor and pipette tip. Optimized for LTS-style pipettors, they feature a unique ‘positive stop' cylindrical collar with a fail-safe mechanism. This innovative design ensures a reliable seal, enhancing both accuracy and precision in assays, and contributes to consistent and reproducible results, while also offering improved ergonomic comfort. Every PosiStop pipette tip undergoes meticulous testing post-cleanroom production, ensuring they are free of detectable RNase, DNase, pyrogens, endotoxins, and PCR inhibitors. This guarantees that valuable reagents remain uncontaminated, optimal and pure. PosiStop Pipette Tips Features Include: • Designed for optimal performance with LTS pipettors, including Diamond PosiStop and Rainin LTS models • Made from medical grade virgin polypropylene, free of any metal contaminants • Rigorously tested and certified to be free from detectable DNase, RNase, pyrogens, PCR inhibitors, and endotoxins, ensuring the highest level of purity for critical experiments • Manufactured in a state-of-the-art 100k cleanroom facility utilizing advanced automated processes • All tips have graduation marks, providing a visual reference to reduce the chance of errors during sample aspiration • Equipped with specially designed polyethylene (PE) filters that effectively block aerosols, significantly reducing the risk of cross-contamination
