Lavender Hemogard™ Closure, Paper Label BD Vactutainer® brand sterile hematology tubes with the BD Hemogard™ closure help to protect lab personnel from contact with blood on the stopper or around the outer rim of the tube, as well as from blood splattering upon opening the tube. The rubber stopper is recessed inside the plastic shield so any drops left by a blood collection needle remain isolated from potential contact.
