Sedigren™ offers a unique approach to performing simple, safe, economical and highly accurate Westergren ESR determinations.
The polystyrene Sedigren™ pipette is graduated from 0 to 160mm and features a special piston located inside the pipette. The piston is designed to use a syringe-like action to draw the blood up to the zero mark. This method eliminates user error and the possibility of air bubble and aerosol formation.
The polypropylene Sedigren™ vial features a removable stopper that is easily pierced with a transfer pipette. The vial is supplied pre-filled with 0.25mL of 3.8% trisodium citrate diluent.
To perform the ESR test, simply add 1mL of EDTA-treated blood into the Sedigren™ vial and invert several times to mix. Insert the pipette through the stopper and push to the bottom of the vial. Place the test unit in the appropriate rack. Then, while holding the pipette down, pull up on the plastic piston until the blood reaches the zero mark. If desired, continue pulling until the piston snaps off at its prescored mark leaving a residual safety plug in the pipette. At the end of 60 minutes, the numerical results are read in millimeters directly from the imprinted scale on the pipette.
The use of Sedigren™ eliminates splashing, spraying and aerosol hazards, making it an optimum choice for ESR testing in the laboratory.
