Small ESR Tube (1.28ml)

The 9×120mm ESR tube is applicable to various automated erythrocyte sedimentation rate analyzers. Due to the small volume and negative pressure inside the tube, some time is required for blood collection. Please wait until the blood stops flowing into the tube. Then, mix the anticoagulant and additive thoroughly by inverting the tube 6-8 times. Improper mixing may cause hemolysis, clotting, or blood bubbles, which may influence the test result.
