The EZ-Rate™ offers a simple, safe, economical and highly-accurate method for performing Westergren ESR determinations directly in 13 mm sodium citrate blood collection tubes.

The polystyrene EZ-Rate™ pipette is graduated from 0 to 180 mm and features a unique fibrous plug located at the zero mark. The plug is specifically designed to be a self-sealing aerosol barrier that stops hazardous substances from escaping through the top of the pipette.
