Product Description
The Axygen® MRF-1000XT-R-S is a 1000 µL extended length filtered sterile pipette tip — racked in hinged racks of 96 tips, 768 tips per pack, 3,840 tips per case (5 packs of 8 racks). Designed for the Axygen® MultiRack pipette tip system. Axygen® MultiRack Filter Tips employ an inert, hydrophobic barrier to prevent contamination from pipettors. The filter materials, containing no leachable additive with less than 20-micron pore sizes, effectively block aerosols without the risk of contaminating the precious sample with additives. 50–1,250 µL working range, 1,250 µL maximum tip capacity. Sterile. Not autoclavable. Blue deck for easy visual identification. Catalog # MRF-1000XT-R-S.

Extended Length — Reaching Deep Vessels at 1000 µL Scale The extended length of the MRF-1000XT-R-S provides additional tip length beyond a standard 1000 µL tip — enabling reliable reach into 15 mL and 50 mL conical tubes, deep reagent reservoirs, deep well plates, and other large-format vessels commonly used in 1000 µL workflows. For labs aspirating from the bottom of tall conical tubes, reaching into deep 96-well or 24-well plates, or working with reagent reservoirs where a standard-length tip cannot access the full depth of the vessel at 1000 µL scale, the extended length format ensures complete, consistent aspiration.
50–1,250 µL Working Range — Maximum Flexibility at Large Volume The MRF-1000XT-R-S has a nominal volume of 1000 µL and a maximum tip capacity of 1,250 µL — covering the full working range from 50 µL through 1,250 µL with a single tip format. This wide working range makes the MRF-1000XT-R-S suitable not only for full 1000 µL transfers but also for any large-volume liquid handling step above 100 µL where the higher tip volume capacity provides a safety margin against tip overflow during aspiration.
Aerosol Barrier Filter — Cross-Contamination Protection at 1000 µL Scale The inert hydrophobic filter barrier of the MRF-1000XT-R-S prevents aerosols and liquid carry-over from entering the pipettor barrel — protecting both the sample and the pipettor at the 1000 µL scale. With less than 20-micron pore sizes and no leachable additives, the filter provides reliable protection for sensitive large-volume molecular biology workflows where sample-to-sample aerosol carry-over at 1 mL volumes would constitute significant cross-contamination risk.
768 Tips per Pack — 1000 µL Rack Format The 1000 µL rack format holds 768 tips per pack (8 racks of 96 tips) rather than the 960 tips per pack of the 100 µL and 10 µL formats — reflecting the larger physical size of 1000 µL tips requiring more space per rack position. 5 packs per case — 3,840 tips per case total. The blue deck color provides universal visual identification of the 1000 µL tip format in mixed-volume tip rack inventories.
Hinged Rack Packaging — 96 Tips per Rack Supplied in hinged racks of 96 tips — the standard rack format for the Axygen® MultiRack system. The hinged lid allows easy one-handed rack opening during active pipetting and reclosure between uses to protect unused tips from contamination.
Axygen® MultiRack System — Compatible with All Major Pipette Brands Designed for the Axygen® MultiRack pipette tip system, compatible with all standard single-channel and multichannel pipettes in the 50–1,250 µL working range from Eppendorf, Rainin, Thermo Fisher, Hamilton, Gilson, and other major pipette manufacturers.
