100–1250 µL Universal Pipette Tips, 84 mm Extended Length, Graduated Blue — Bulk, Racked, Filtered & Sterile These Globe Scientific 100–1250 µL universal pipette tips deliver a certified, graduated fit across most standard pipettors, with an 84 mm extended-length body for reaching deep tubes and reservoirs. Engineered for accurate liquid handling, the tips support general reagent dispensing, serial dilutions, and plate-based sample prep on the bench or in automated workflows. Available in four packaging formats, the family lets labs match throughput and contamination-control needs without changing tip geometry. Bulk bags suit high-volume manual work, while racked, filtered, and sterile options serve nucleic-acid, cell-culture, and PCR setup where carryover matters.

These are universal-fit tips designed to seat on most standard single- and multichannel pipettors covering the 100–1250 µL range. We recommend verifying fit with a sample before standardizing a large order. What is the difference between the filtered and sterile formats? The filtered format (151153BRF) includes a barrier to limit aerosol carryover and is supplied as refill plates. The sterile format (151153BRS-96) is racked and certified sterile for contamination-sensitive work; these are distinct features, not combined in one SKU. How many tips come in each package? The bulk bag holds 1000 tips. Racked and sterile boxes contain 96 tips per rack across 6 racks (576 tips). The filtered option ships as 5 refill plates of 96 tips each (480 tips). Why choose the 84 mm extended length? The extended body reaches into deep tubes, conical vessels, and tall reservoirs without contaminating the pipette barrel, improving access and reducing cross-contamination risk during high-volume transfers. { "@context": "https://schema.org", "@type": "Product", "name": "100–1250 µL Universal Pipette Tips, 84 mm Extended Length, Graduated Blue", "brand": {"@type": "Brand", "name": "Globe Scientific"}, "description": "Certified universal 100–1250 µL extended-length graduated blue pipette tips available in bulk bag, racked, filtered, and sterile formats.", "offers": { "@type": "AggregateOffer", "priceCurrency": "USD", "lowPrice": "41.00", "highPrice": "71.90", "offerCount": "4", "offers": [ {"@type": "Offer", "sku": "151153B", "price": "50.60", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "151153BR-96", "price": "61.30", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "151153BRF", "price": "41.00", "priceCurrency": "USD"}, {"@type": "Offer", "sku": "151153BRS-96", "price": "71.90", "priceCurrency": "USD"} ] } } { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [ {"@type": "Question", "name": "Are these tips compatible with my brand of pipette?", "acceptedAnswer": {"@type": "Answer", "text": "Yes.
