AeroGard™ Aerosol-Barrier Pipet Tips

Non-wettable Zero-Fluid-Retention pipet tips with beveled-ends assure accuracy and reproducibility, allowing micro-volume dispensing without the need to "touch-off". Aero-Gard barriers block aerosols by coalescing radio-active, 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. Debris-free, non-reactive barriers are manufactured without surfactants, or other extractable components, to precise air-flow standards. AeroGard/UniFit tips are specifically designed for use with Pipetman, Eppendorf, Finnpipette and other research-grade pipettors. Offered in maximum volumes of 30 uL, 100 uL, 140 uL, 200 uL, 230 uL or 1,000 uL. Applications include any discrete sampling procedure requiring an aerosol-free system for transferring volatile or hazardous samples.

MicroFlex™ and DecaFlex™ Gel-Loading Pipet Tips

Universal-fitting MicroFlex microcapillary pipet tips allow positive-displacement accuracy and reproducibility using Pipetman, standard Eppendorf, Finnpipette, Socorex, and Volac single-channel air-displacement pipettors. Similarly, DecaFlex tips eliminate fluid retention and ensure total sample recovery with Eppendorf Ultra-Micro pipettors. RNase/DNase-free, MicroFlex and DecaFlex tips feature three styles of flexible, 33mm long, 5 uL microcapillary tube sections with beveled ends. Provides precise control when loading vertical gel electrophoresis apparatus, aspirating supernatants away from pellets, utilizing expensive reagents, and other discrete sampling applications. Round-shaft tip with 0.57mm OD tube end, greatly improves loading techniques for 0.75, 1.0 and 1.5mm PAGE gels. Intermediate 0.37mm OD flat tip is ideal for loading 0.4mm sequencing gels while ultra-thin 0.17mm OD flat tip is perfect for loading 0.2mm wedge-spacer gels. shown in enlarged-view photo, flat or round shaft styles allow tips to be fully inserted, enabling wells to be filled equally from the bottom up, thus providing a uniform environment for electrophoresis. Non-autoclavable MicroFlex and DecaFlex tips are offered MaxiRack packs of 200 tips, or in radiation sterilized RadPacks.

UniFit™ ZFR™ Pipet Tips and Pre-Lubricated SlickTips™ in Ecology MiniStacks

Same great UniFit Zero-Fluid-Retention Tips and Pre-Lubricated SlickTips in environmentally friendly packaging. Both small 200 uL and large 1,000 uL universal-fit pipet tips are available in a MiniStack pack designed to save space in shipping, storage, and on the lab bench. Stackable trays also require much less plastic than our industry standard packs of ten complete MiniRacks with bases and lids. Fully autoclavable MiniStacks employ a MiniRack and four stacking trays each supporting 96 UniFit pipet tips which nest into tips in tray below. A single base plate and lid protect tips from contamination. Lid may be moved from one tray to the next as the 480 tips per MiniStack are used. New, wider base design employs microtiter plate size and format which ensures standardization for automated workstations. 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. While all UniFit pipet tips are always made from 100% virgin polypropylene, the entire MiniStack rack is made from 100% recycled material.

UniPette™ ZFR™ Pipet Tips in Ecology ReloadStacks™

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. By mounting each consecutive Tray onto an open BoxBase, the lab tech creates their own MiniRack, as needed. By slipping the rectangular plastic LidRing over the top of any one of the Trays, their MiniRack is fitted with a folding Lid. When a Tray of 96 Tips is empty, 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. StarterSets of extra BoxBases and HingedLids are included at no charge with initial orders. Patents Pending.
