Product general situation:
Erythrocyte sedimentation rate (ESR), also known as sedimentation rate or Wilcoxon Westergren 

sedimentation rate, for red blood cells within one hour settling velocity, it is a commonly used blood 

test and a kind of inflammation of the specific detection. When tested, the ESR of diluted with anticoagulant 

blood samples were placed in vertical tube is widmanstatten blood sedimentation tube), a period of time after 

the tube body scale, be able to read cell settling velocity (mm / h).
Westergren's erythrocyte sedimentation rate (ESR) system for collecting blood samples and anticoagulation 

of blood sedimentation test tube (built-in 3.8% sodium citrate additive), a slender tube with the ESR of the 

piston (Wechsler blood sedimentation tube) and Westergren's erythrocyte sedimentation rate (ESR) frame

ESR tubes (Wechsler blood sedimentation tube) is made of high transparent polypropylene (PP) made 

clear scale being easy for a user to accurately read the scale value. The upper end of the ESR pipe is 

embedded with a filter core to prevent dirt from entering the top of the pipe body. ESR tube lower 

part with piston.
