Plugged pipets, calibrated to deliver with blow-out, offer long, slender, tapered tips to make pipetting go faster and easier. All tips fire-polished for burr-free, even flow rates. Easy-open steri-view wrappers (one side paper, one side plastic) have color-coded sizes printed directly on the paper for easy identification by size. Colors conform to ISO standards.
