K2EDTA and K3EDTA tubes:
The inner wall of VACUETTE® EDTA tubes is coated with spray-dried K2EDTA or K3EDTA. EDTA acts as an anticoagulant, binding the calcium ions and interrupting the clotting cascade. These tubes are used primarily in haematology.
K2EDTA with separator gel:
K2EDTA tubes with separator gel are particularly suitable for molecular diagnostics and viral load determination.
