EDTA K2/K3 Disposable Vacuum Blood Collection Tubes (Lavender Top / CBC Tubes)

This lavender-top EDTA tube serves as the cornerstone consumable for clinical laboratories worldwide, thanks to its streamlined operation and universal sample compatibility. By encapsulating complex anticoagulation needs into a safe, easy-to-use vessel, we are committed to providing global users with a reliable and safe disposable blood collection solution.

Application Scenarios & Core Uses

Routine Outpatient Diagnostics: The first-choice tube for general health check-ups and basic disease screening, providing essential CBC data.

Emergency & Critical Care: Rapid hematology and coagulation assessment in ERs and ICUs, delivering immediate data for life-saving clinical decisions.

Hematological Disease Support: Providing accurate cellular counts for the screening and monitoring of leukemia, anemia, and other blood disorders.

Pre/Post-Operative Management: Assessing platelet function and baseline blood status to identify bleeding risks before surgery and monitor recovery.

Product Details

Dual-Potassium Formula, Flexible Adaptation

Catering to laboratory equipment habits in different regions globally, we supply both EDTA K2 (primarily spray-dried powder, with minimal impact on cellular osmotic pressure) and EDTA K3 (liquid pre-filled, providing ultra-fast anticoagulation). Buyers can freely choose the most suitable anticoagulant tube based on the model of their hematology analyzers.

Micron-Level Uniform Spray-Coating

For K2 powder tubes, we employ high-precision micron-level spray-drying technology to uniformly coat the anticoagulant powder on the inner wall. After blood collection, the blood rapidly and evenly wets and dissolves the powder, preventing localized high concentrations that could cause pseudothrombocytopenia or cell aggregation, ensuring hematology tubes deliver accurate results right out of the gate.

Whole Blood Direct Testing, No Centrifugation Needed

Unlike tubes requiring centrifugation to separate serum, the design philosophy of EDTA tubes is to preserve the whole blood state. Samples inside the tube can be directly loaded onto machines for advanced tests like 5-part differential counts and reticulocyte counting, significantly simplifying the workflow in clinical labs and shortening TAT (Turnaround Time).

Color Psychology Anti-Error Design

The cap features an internationally recognized Lavender (light purple) color, which has high visual distinctiveness. In high-throughput emergency or physical examination settings, nurses can identify the use of a CBC blood collection tube in just 0.5 seconds by color alone, preventing clinical errors such as drawing the wrong tube order (e.g., mistakenly using a heparin tube which would invalidate results).
