SF-BesTip™ Superior Technology is satisfaction guaranteed. Our SF-BesTips, designed with softer, more pliable plastic, tapered orifices, and thinner walls, are superior in accuracy and reproduciblity when compared to popular brands. SF-BesTips are manufactured from superior resin polymer technology to enhance liquid handling performances. SF-BesTips are uniquely designed with ultra-thin, flash-free 'tapered orifices' to reduce liquid surface retention while maximizing hydrophobic (low binding) properties for greater sample delivery and recovery. Specifically, when compared to popular beveled orifice style pipet tips, our SF-BesTips with 'tapered orifices' are more accurate and reproducible. Our comparative research shows that our 'tapered orifice' SF-BesTips have 3 times less liquid retentive orifice surface area than beveled versions. Satisfaction is guaranteed. If not, return product for a full refund. BesTip also feature flare-like SecuRings™ to assure complete and universal pipettor attachment and easy ejection.
