UniFit Zero-Fluid-Retention Pipet Tips NS invented the universal-fitting Pipet Tip 25 years ago. Since then, the beveled orifices of our UniFit Tips, and our exclusive Zero-Fluid-Retention resin technology, have ensured superior sample recovery while increasing accuracy and reproducibility for pipetting liquid in micro-volumes. UniFit universal-fitting ZFR Pipet Tips accommodate all single and multi-channel pipettors including UniPette, Pipetman, Eppendorf, Biohit, BrandTech, Capp, HTL/Labnet--Axygen/VWR, Jencons, Nichiryo/Oxford, Socorex/Wheaton, and Thermo-Fisher/LabSystems. 200ul size UniFit Tips also fit Finnpipette, MLA and VistaLab pipettors. Reinforced base design, and precisely spaced 8 x 12 countersunk hole-pattern of our MiniRacks and Trays, ensures perfect Tip alignment for rapid mounting of 10μl, 200μl, and 300μl UniFit Tips on all multi-channel pipettors. Every Tip size is offered in DispenserPack Bags, and in fully-autoclavable MiniRacks, MiniStacks, and ReloadStacks, to cover all possible lab requirements. Premium Packaging is Standard for UniFit Pipet Tips UniFit ZFR Pipet Tips are always packed in premium packaging, featuring our unique Stand-Up DispenserPacks for all BulkPack Tips, as well as improved MiniRacks, Ecology MiniStacks, and Ecology ReloadStacks for all RackPack Tips. For example, our hermeticallysealed DispenserPacks have a tamper-evident sealing strip above the zip-lock closure. These puncture resistant nylon bags ensure package integrity and product cleanliness from the manufacturer to the lab. Super-wide gussets at bottom of DispenserPacks allow them to stand upright on the lab bench, and to maintain a wide-open stance for aseptic removal of one Tip or Tube at a time, thus eliminating excess handling and minimizing risk of RNase contamination. Also, with our more stable, microtiter-plate sized basedesign, all of our Pipet Tip Racks employ a massive internal rib structure which provides an extremely strong, non-flexing platform. All Rack and Tray deck surfaces feature 96 or 100 individual collars, into which each Pipet Tip nests, ensuring perfect Tip alignment whenever a multi-channel Pipettor is used. And, our traditional lift-off Lids, or new self-hinged Lids and Bases, assure maximum convenience with our Rack and Tray designs.
UniFit ZFR Pipet Tips in BulkPacks and MiniRacks All UniFit Tips are molded in our exclusive Zero-Fluid-Retention polypropylene resin Homopolymer PP plastic is ADC/bovine-free Tips fit all single and multi-channel pipettors Beveled orifices for total sample recovery All MiniRacks and Lids are molded exclusively of internally-generated recycled polypropylene to ensure utmost cleanliness and performance The invention of National s Zero-Fluid-Retention Tips combines over 10 years of research and development with petrochemical producers to bring our customers an exclusive solution for pipet tip performance. No other pipet tip will retain less fluid than our UniFit Zero-Fluid-Retention Pipet Tips which are available in BulkPacks and MiniRacks. While our 96-Hole Mini- Racks have traditionally been supplied with standard Lift-Off Lids and MiniRack Bases, they are also available with our new HingedLids and BoxBases. Fully described on the following pages, these new components can be combined with our 96-Hole Trays to form completely unique Ecology MiniRacks. With our new ecological version, you can enjoy the familiar convenience of individual MiniRacks, but without the waste of throwing away all the components after 96 Pipet Tips have been consumed. Instead, just dispose of the empty Tray, place another full Tray onto the same BoxBase, and reuse the same HingedLid. Both our traditional MiniRacks, and our new Ecology MiniRacks, share the same footprint, and fit in the same packaging. Most UniFit ZFR Tips are also available as pre-lubricated SlickTips at the same prices. Call for details.

UniFit ZFR Pipet Tips in Ecology MiniStacks Nested UniFit Tips in MiniStacks save space Solid, wide base MiniStack eliminates tipping Just dispose of each empty Tray in sequence Tips fit all single and multi-channel pipettors Very environmentally friendly use of plastic Same great UniFit Zero-Fluid-Retention Tips in environmentally friendly packaging. The MiniStack pack is designed to save space in shipping, storage, and on the lab bench. Fully autoclavable MiniStacks employ a MiniRack and four stacking Trays, each supporting 96 UniFit Pipet Tips which nest into Tips in Tray below. Lid may be moved from one Tray to the next as the Tips are used. Larger footprint eliminates problem of tall stacks tipping over, even when using a multi-channel pipettor on an outer row of Tips in the top Tray. All racks are made from 100% recycled material. Most UniFit ZFR Pipet Tips are also available as pre-lubricated SlickTips at the same prices. Call for details. All MiniStacks and ReloadStacks on these pages are molded exclusively of internally-generated recycled polypropylene, ensuring the utmost cleanliness and performance of all our Racks. While our 96-Hole MiniStacks have traditionally been supplied with standard Lift-Off Lids and Mini- Rack Bases, they are also available with our new HingedLids and BoxBases. More fully described on the next page, the photos show how these two new components can be combined with our Stacking Trays to form a complete MiniStack. Since the new BoxBase, HingedLid, and existing Trays are effectively interchangeable with our standard MiniRack, Lift-Off Lid, and existing Trays, both versions share the same footprint, and fit in the same packaging.

UniFit ZFR Pipet Tips in Ecology ReloadStacks Nested UniFit Tips in ReloadStacks save more space Transfer Trays and HingedLids to create MiniRacks Reuse Bases and Lids, just dispose of Trays Tips fit all single and multi-channel pipettors The Green Solution ReloadStacks represent the most efficient and cost-effective use of plastic components yet available. Most environmentally friendly use of plastic Similar in concept to our popular MiniStacks, new ReloadStacks utilize the same Trays of 96 Tips with a completely different Base and Lid. Instead of the traditional MiniRack Base and Lift-Off Lid, ReloadStacks are fitted with an open BoxBase and a unique HingedLid. Simply by mounting each consecutive Tray onto an open BoxBase, the lab tech creates their own MiniRack, as needed. Then, by slipping the rectangular plastic LidRing over the top of any one of the Trays, their MiniRack is fitted with a folding Lid. This novel Lid is self-hinged, and will stay in virtually any position once it is fully flexed open during its first use. When a Tray of 96 Tips is empty, simply pull off the HingedLid, unsnap the Tray from its BoxBase, and mount the next Tray onto the same Base. Slip the LidRing over that Tray, use this next MiniRack until it is empty, and repeat the simple procedure. Because the Base and Lid are continuously reused, this system utilizes far less plastic resin than other Tip Racks. ReloadStacks also have a much smaller footprint than any previous version, thereby saving even more space in shipping, storage, and on the lab bench. When all Trays are empty, the BoxBase and HingedLid can be combined to create a handy lab StorageBox, or they can be reused with another set of 10 Trays from the next ReloadStack pack. StarterSets of extra BoxBases and HingedLids are included at no charge with initial orders. Patents Pending. All components are fully autoclavable. Most UniFit ZFR Pipet Tips are also available as pre-lubricated SlickTips at the same prices. Call for details.

AeroGard Perfect-Barrier ZFR Pipet Tips Barriers block aerosol/liquid cross-contamination Use finest porous plastic filter membrane available Filters are free of particles, starch, and surfactants Unlike others, AeroGard Tips are fully autoclavable Filter Tips fit all single and multi-channel pipettors AeroGard Tips are RNase/DNase and pyrogen-free Non-wettable Zero-Fluid-Retention Pipet Tips with beveled ends assure accuracy and reproducibility. Aero-Gard barriers block aerosols by coalescing radioactive, chemical, or biological contaminants before they can come in contact with pipettor shafts. Effectively eliminates unwanted signals induced by residual RNA/DNA transfered in trace amounts by aerosol cross-contamination. Also acts as a safety barrier against accidental over-pipetting of liquid without risk of sample lock-up. AeroGard/UniFit Tips are compatible for use with UniPette, Pipetman, Eppendorf and other pipettors. Available in Sterile or non-sterile MiniRacks of 96 Filter Tips, or in reclosable, stand-up DispenserPack bags (see page 2 for details).
