Levram Vacuum Blood Collection Tubes with K2 EDTA and a double cap are designed for safe and efficient blood sample collection for hematological testing. These tubes, often used in complete blood counts (CBC) and other hematology studies, utilize K2 EDTA as an anticoagulant to prevent blood clotting and maintain sample integrity. The double cap design helps minimize contamination risks, and the vacuum system ensures easy and accurate blood draws.
