UniFit™ ZFR™ (Zero Fluid Retention) Tips and Pre-Lubricated SlickTips™
 Universal Fitting Pipet Tips. Invented by NSS. Copied by Others.
When it comes to pipetting micro-volumes of fluid, National Scientific has long recognized
that accuracy and reproducibility are essential for high quality research. Any fluid retention in a pipet tip must be considered unacceptable. Thus, we have been producing beveled,
non-wettable UniFit™ tips for many years. No other manufacturer produces pipet tips which retain less fluid than National Scientifics Zero-Fluid-Retention tips. We think you will
appreciate high performance ZFR™ tips and pre-lubricated SlickTips™, now offered in new premium packaging featuring stand-up
DipenserPacks for all bulk-packaged products, improved MiniRacks™, and new Ecology MiniStacks™
for both 200ul and 1000ul beveled tips. New, bi-directional hinged lid assures maximum convenience
during use. Puncture resistant, laminated nylon pouches ensure package integrity, product cleanliness, and meet sterile packaging standards that cannot be matched by
cellophane “cigarette” wrap. Hermetically sealed DispenserPacks also feature a tamper-evident seal and reclosable zip-lock. Super-wide gussets at bottom of
Dispenser-Packs allow them to stand upright on the lab bench for aseptic removal of one tip or tube at a time. Get the quality, price, performance, and value
combination that only ZFR™ UniFit™ Pipet Tips, and Pre-Lubricated SlickTips™, provide.
UniFit™ ZFR™ Pipet Tips and Pre-Lubricated SlickTips™ in Ecology MiniStacks™
Ecology MiniStacks. Invented by NSS. Copied by Others.
Same great UniFit™ Zero-Fluid-Retention Tips and Pre-Lubricated SlickTips™ in environmentally friendly packaging. Both small 200ul and large 1,000ul 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 Mini-Stacks™ 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.
