ESR Tube Small (1.28ml)

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