MultiMax™ B-2102 | 20µL Barrier Pipette Tips, Low Binding, Sterile — 960/Pack (96/Rack, 10 Racks)

The LIGHT LABS MultiMax™ B-2102 | 20µL Barrier Pipette Tips (manufacturer SKU 2937T / Sorenson catalog # 14210T) are 20µL sterile, low-binding barrier pipette tips — crafted from premium, low-binding virgin polypropylene and engineered for exceptional accuracy, precision, and contamination protection across standard 20µL pipetting applications. Protect your samples and achieve superior results with MultiMax™ Universal Fit Barrier Tips by Sorenson. Volume range: 1–20µL. Hydrophobic barrier prevents pipettor contamination. Low-binding surface technology for maximum sample recovery. Sterile. Certified RNase/DNase Free, Human DNA Free, PCR Inhibitor Free, and Pyrogen Free. 96 tips per CellRack, 10 racks per pack, 960 tips per pack.

Hydrophobic Barrier — Pipettor Protection Against Aerosol and Cross-Contamination Your pipettor is protected from aerosol contamination by an inert, hydrophobic barrier that takes potential contaminants out of the pipettor airstream. The inert hydrophobic barrier of the Sorenson MultiMax™ 20µL tip physically blocks aerosol droplets and liquid from entering the pipette body during aspiration — protecting both the pipette and subsequent samples from cross-contamination. The aerosol barrier will not trap liquid or contaminate samples in the event of over-pipetting. Should over-pipetting occur, your sample can be safely and easily retrieved. The filter matrix is pure polyethylene, free from additives, particulates, or contaminants that can alter sample integrity — a critical specification for sensitive molecular biology applications where filter material compatibility directly affects assay results.

Low-Binding Surface Technology — Maximum Recovery for Small-Volume Precision Work Tips feature a new surface technology designed for quantitative assays in which sample binding can significantly alter results or for critical small volume protocols that require a high degree of accuracy. At 20µL scale, the volume of sample retained on the inner tip surface as a thin film represents a disproportionately large percentage of the total sample compared to larger-volume tips — making low-binding surface technology especially critical at this volume. The low-binding polypropylene of the Sorenson MultiMax™ 20µL tip minimizes non-specific adhesion of nucleic acids, proteins, enzymes, antibodies, and other biomolecules — delivering the full dispensed volume to the destination vessel for maximum assay accuracy and reproducibility. Ideal for molecular biology applications such as PCR.

Volume Range: 1–20µL — Full Coverage of the 20µL Pipette Range The 1–20µL volume range of the Sorenson MultiMax™ 20µL tip accommodates the complete pipetting range of all standard 20µL pipettes — from single-microliter dispensing of precious samples to full-volume 20µL transfers. This full-range coverage eliminates the need for separate tip formats across the 20µL pipette range.

MultiMax™ Universal Fit — Compatible with All Major Pipette Brands MultiMax™ Universal Fit Barrier Tips are designed to fit all major brands of single and multichannel research-grade pipettes — including Eppendorf, Gilson, Thermo Fisher, Rainin, Brand, and other standard pipette platforms. Universal fit is achieved through a precisely engineered tip cone geometry that forms a reliable, leak-free seal across the range of cone diameters used by major pipette manufacturers — without requiring brand-specific tip variants or adapters. Fit most popular brand pipettors. Stable racks that are perfect for multichannel pipettes.

CellRack Packaging — Stable, Convenient Tip Access for Single and Multichannel Pipettes 96 tips per polypropylene CellRack, 10 racks per pack. The stable polypropylene CellRack design provides a firm, non-flexing rack that remains stable during single-channel and multichannel pipetting — critical for multichannel pipette loading where rack stability directly determines whether all 8 or 12 tips load simultaneously with consistent seating force. Sterilized and individually shrink-wrapped — stable racks that are perfect for multichannel pipettes. Individual shrink-wrapping of each rack maintains sterility until the moment of use and protects unused tips from contamination after partial rack use.
