Product Description
LIGHT LABS is proud to offer the Sorenson BioScience 20 µL Non-Graduated Barrier Pipette Tip in Low Binding MultiRack format (Cat # 77260T) — a premium, sterile, low binding 20 µL barrier tip designed for precision micro-volume pipetting in the 1–20 µL range with maximum contamination protection and minimal sample loss. The 77260T is constructed from a 200 µL tip body with the barrier positioned at the 20 µL level — a design approach that provides a wider bore tip body than a dedicated 20 µL tip, ensuring easier pipettor fit and improved airflow around the barrier for reliable aerosol protection without compromising dispensing accuracy.
The non-graduated design of the 77260T is the preferred format for high-throughput applications where volume delivery is controlled entirely by the calibrated pipettor — eliminating the unnecessary visual clutter of graduation lines that can be distracting during repetitive, rapid pipetting workflows such as PCR setup, 96-well plate liquid handling, and automated liquid dispensing. The proprietary low binding surface treatment minimizes non-specific adsorption of DNA, RNA, proteins, enzymes, and other precious biological reagents to the polypropylene tip wall — reducing sample loss and improving accuracy when working with limiting or high-value samples in the 1–20 µL range where even small adsorptive losses can significantly impact results.
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. The MultiRack format provides 96 tips per refillable, stackable rack with 10 racks per pack (960 tips total). Universal fit on standard research-grade single and multichannel pipettors. LIGHT LABS is your trusted source for Sorenson BioScience pipette tips.
KEY FEATURES
- 20 µL non-graduated design — preferred for high-throughput pipetting where volume delivery is controlled by the calibrated pipettor; clean, uncluttered appearance for fast repetitive pipetting
- 200 µL tip body filtered at the 20 µL level — wider bore tip body vs. dedicated 20 µL tips; easier pipettor fit and improved airflow around barrier for reliable aerosol protection
- Low binding surface technology — minimizes non-specific adsorption of DNA, RNA, proteins, enzymes, and other precious biological reagents; reduces sample loss in the critical 1–20 µL micro-volume range
- 1–20 µL volume range — full coverage of standard 2 µL, 10 µL, and 20 µL pipettor volumes
- Inert hydrophobic barrier — prevents aerosol and liquid from entering and contaminating the pipettor; barrier will NOT trap liquid or contaminate samples during over-pipetting
- Fits standard universal pipettors — compatible with all major single and multichannel pipettor brands
- MultiRack format — 96 tips per refillable, stackable rack; 10 racks per pack;
- Sterile — gamma irradiated
- Certified RNase-free, DNase-free, human DNA-free, PCR inhibitor-free, and nonpyrogenic
- Made from 100% virgin polypropylene (PP)
