BeneSphera ESR Tubes are single use devices intended to be used as whole blood sample tubes for the quantitative determination of Erythrocyte Sedimentation Rate (ESR).

• Certified Calibration of Accuracy and Precise Graduations
• Clear, Bold, Bi-directional Graduations
• Filter Plug - Prevent aerosol or liquid contamination of the pipetting device while further reducing sample-to-sample contamination risks
• Negative Graduations - Increase pipette capacity, and accommodates additional volumes

An Erythrocyte Sedimentation Rate (ESR) is a test for finding out presence of inflammation or infections in the body.
