Poly Esrite offers a simple, safe, economical and highly-accurate method for performing Westergren ESR determinations directly in a 13mm sodium citrate blood collection tube.
The PolyEsrite pipette is graduated from 0 to 180mm 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.
To use, simply insert the PolyEsrite pipette into the blood collection tube. Then, using continuous force, push the pipette down to the bottom of the tube. The blood will automatically rise into the pipette and stop at the zero mark. Place the test unit in the ESR rack. At the end of 60 minutes the numerical results are read in millimeters directly from the imprinted scale on the pipette.
Main Points For direct testing in 13mm blood collection tubes No need to transfer blood No additional vials, tubes or transfer pipettes necessary Accurate and reproducible results Fibrous barrier protects user from hazardous aerosols
