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 from 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 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
• Featuring color-coded rack inserts for quick and effortless identification and matching with Diamond™ PosiStop™ pipettors
• 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
• Available in a variety of styles to meet specific requirements: Filter, non-filter, standard, and low retention options
• Offered in multiple packaging formats: Rack, bulk, reload, and eco-friendly GreenRacks™
