5 mL K₂EDTA Polystyrene Blood Collection Tubes (15×54 mm) – K6740
Mid-Volume EDTA Tubes for Routine Blood Collection
The K6740 tube is a 5 mL blood collection tube made from clear polystyrene, treated with dried K₂EDTA anticoagulant (8.75 mg per tube, which corresponds to 1.75 mg K₂EDTA per mL of blood). It measures 15×54 mm externally and is fitted with a pink screw cap. Designed for labs needing moderate sample volumes with standard EDTA treatment, stable performance, and clear visibility.
