100–1250 µL Universal Low-Retention Pipette Tips, Graduated 84 mm Extended Length, Sterile The Globe Scientific 100–1250 µL Universal Low-Retention Pipette Tips deliver maximum sample recovery for viscous reagents, nucleic acid prep, and quantitative assay setup. Their low-retention surface minimizes liquid film, improving accuracy in qPCR master-mix dispensing, protein normalization, and serial dilution. Universal-fit geometry seats on most standard pipettors, while graduated, extended-length design supports deep-well and tube reaching.

Frequently Asked Questions What is the difference between the filtered and non-filtered racked tips? SKU 150053RFS includes an integrated aerosol/liquid barrier filter that blocks aerosols and prevents pipettor contamination, ideal for PCR and DNA/RNA work. SKU 150053RS is racked and sterile without a filter for general transfers. Are these tips truly universal fit? Yes. The universal geometry is engineered to seat securely on most standard single- and multi-channel pipettors in the 100–1250 µL range. We recommend verifying fit with your specific pipettor model for critical applications. What does "low retention" mean for my results? The hydrophobic tip surface reduces liquid film that clings to standard polypropylene, improving recovery and dispensing accuracy for viscous, protein-rich, or surfactant-containing samples. Are all three packaging formats sterile? Yes. The bulk bag (150053), racked (150053RS), and racked filtered (150053RFS) options are all supplied sterile and certified. Lot numbers on each package support QA traceability. { "@context": "https://schema.org", "@type": "Product", "name": "100–1250 µL Universal Low-Retention Pipette Tips, Graduated 84 mm Extended Length, Sterile", "brand": { "@type": "Brand", "name": "Globe Scientific" }, "description": "Globe Scientific 100–1250 µL universal low-retention sterile pipette tips, graduated 84 mm extended length, available in bulk, racked, and filtered racked formats.", "offers": { "@type": "AggregateOffer", "priceCurrency": "USD", "lowPrice": "61.30", "highPrice": "82.70", "offerCount": "3", "offers": [ { "@type": "Offer", "sku": "150053", "price": "72.00", "priceCurrency": "USD" }, { "@type": "Offer", "sku": "150053RS", "price": "82.70", "priceCurrency": "USD" }, { "@type": "Offer", "sku": "150053RFS", "price": "61.30", "priceCurrency": "USD" } ] } } { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ { "@type": "Question", "name": "What is the difference between the filtered and non-filtered racked tips?", "acceptedAnswer": { "@type": "Answer", "text": "SKU 150053RFS includes an integrated aerosol/liquid barrier filter that blocks aerosols and prevents pipettor contamination, ideal for PCR and DNA/RNA work.
