Product Description
LIGHT LABS is proud to offer the Sorenson BioScience 10 µL Sharp Barrier Pipette Tip in MultiRack format (Cat # 77250T) — a premium, sterile, 10 µL barrier tip engineered specifically for precision dispensing into small wells, gel loading slots, capillaries, and other confined spaces requiring a fine, sharp tip profile for accurate micro-volume delivery. The Sharp design features an exceptionally narrow, fine tip point that minimizes the tip's footprint at the point of dispensing — enabling researchers to target small wells and confined openings with greater accuracy and control than standard wide-bore 10 µL tips.
The 77250T features the finest graduation resolution of any Sorenson 10 µL barrier tip — with graduation lines at 1 µL, 2 µL, 5 µL, and 10 µL providing four distinct visual reference points for precise volume confirmation across the full 0.1–10 µL working range. This level of graduation detail is critical for accurate micro-volume delivery in applications such as PCR setup, sequencing reaction preparation, and gel loading where small volume errors can have significant downstream consequences. The extended length design allows the tip to reach the bottom of microcentrifuge tubes, PCR tubes, and other small vessels without contaminating the pipettor shaft — a key safety and accuracy feature when working with sub-10 µL volumes.
The inert hydrophobic barrier prevents aerosols and liquids from entering and contaminating the pipettor — and will not trap liquid or contaminate samples even in the event of over-pipetting. Universal fit on standard research-grade single and multichannel pipettors. The MultiRack format provides 96 tips per refillable, stackable rack with 10 racks per pack (960 tips total). Certified RNase-free, DNase-free, human DNA-free, PCR inhibitor-free, and nonpyrogenic. LIGHT LABS is your trusted source for Sorenson BioScience pipette tips.
