Customized Medical Vacuum Blood Collection Tube Vacuum Blood Collection
Our 1.28ml ESR Tube is not a standard tube; it is a precision instrument designed specifically for the manual Westergren method, the historical reference procedure for Erythrocyte Sedimentation Rate (ESR). Its unique 1.28ml draw volume is critically calculated to achieve the exact 4:1 blood-to-anticoagulant ratio and, when used with a standard Westergren pipette, creates the required 200mm test column without the need for manual dilution or volume adjustment. This eliminates a key source of pre-analytical error and ensures method compliance.
