BD Vacutainer SPC Plus Venous Blood Collection Tubes are specialized plastic tubes designed for reliable and efficient blood sample collection, particularly for trace element testing. Each 13 x 100 mm tube has a 6 mL volume and contains 10.8 mg of K2 EDTA additive, which acts as an anticoagulant to preserve whole blood samples. Featuring a distinctive Royal Blue BD Hemogard™ Closure, these tubes offer enhanced safety by recessing the rubber stopper within a plastic shield, helping to prevent contact with blood and reduce splattering upon opening. The clear plastic construction allows for accurate volume assessment, and these tubes are 510(k) cleared, ensuring they meet stringent quality and safety standards.
