Our Disposable Medical Consumable EDTA Blood Collection Tubes (purple top) are designed for reliable hematology specimen collection, stabilization, and transport. Available in both plastic (PET) and glass formats, and in common volumes (2 mL, 3 mL, 4 mL, 5 mL, 7 mL, 10 mL), these tubes ensure reproducible blood-to-anticoagulant ratios and consistent performance across routine and high-throughput laboratory workflows.
Accurate hematology results: EDTA anticoagulant prevents clotting while preserving cell morphology for complete blood counts and differential analysis.
Consistent additive delivery: Additive is spray-coated (K2) or supplied in liquid form (K3) in strict manufacturing control to ensure uniform distribution and correct blood-to-anticoagulant ratio.
Vacuum integrity: Manufactured and tested for vacuum stability to deliver correct fill volumes and sampling reliability.
Compatibility: Compatible with standard multi-sample needles and most automated hematology analyzers; suitable for centrifugation and downstream testing.
Sterile and non-pyrogenic: Produced in controlled environments; sterilized and packaged to clinical standards for safe sample handling.
Tube color: Purple (EDTA)
Anticoagulant: EDTA (K2 spray-coated or K3 liquid)
Material: PET (plastic) or glass options
Closure: Hemogard / rubber stopper — tight seal for vacuum retention
Sterility: Gamma sterilized or ETO (depending on SKU)
Shelf life: typically 12–36 months, depending on storage — check the lot label for expiry
Regulatory / Quality: Manufactured under ISO quality systems; options for CE marking/supplier 510(k) documentation are available upon request for specific SKUs.

Designed for collection, transport, and short-term storage of human venous blood for hematology assays (CBC, reticulocyte count, blood typing and other whole-blood analyses). Not intended for therapeutic use; for in vitro diagnostic procedures only. Follow your laboratory’s standard operating procedures for specimen collection and handling.
Inspect tube integrity and expiry before use.
Use appropriate venipuncture technique and a matching needle/hub for vacuum tubes.
Fill to the indicated volume; do not underfill or overfill — correct blood: anticoagulant ratio is critical (standard is 1:9).
Immediately invert gently 8–10 times after collection to mix blood and anticoagulant; avoid vigorous shaking.
Store and transport at recommended temperatures; centrifuge where required per assay protocol.
Dispose of used tubes as medical waste in accordance with local regulations.
Manufactured in facilities that observe ISO quality management practices.
Additive application and vacuum retention are validated to ensure lot-to-lot consistency.
Available documentation: Certificate of Analysis (CoA), sterility certificate, and, for specific SKUs, CE supportive documentation on request.
This product is an in vitro diagnostic medical device. Users must follow local regulations and institutional policies for clinical specimen collection and disposal. For documentation (MSDS, sterility and test reports), request the relevant lot documentation when placing an order.
EDTA tube is a type of blood collection tube that contains ethylenediaminetetraacetic acid (EDTA) as an anticoagulant. EDTA works by binding to calcium ions in the blood, which prevents clotting and helps preserve the sample for laboratory analysis.
The primary purpose of using EDTA tubes is to collect blood samples for various laboratory tests, particularly those related to blood cell counts and blood typing. EDTA helps maintain the integrity of the blood sample by preventing coagulation and ensuring reliable test results.
EDTA works by chelating calcium ions in the blood, which are essential for the coagulation process. By binding these ions, EDTA prevents clot formation.
Sinymedical offers K2 and K3 EDTA tubes, which differ in the number of potassium ions they contain, catering to various laboratory needs.
K2 EDTA tubes contain dipotassium EDTA, while K3 EDTA tubes contain tripotassium EDTA, differing in concentration and specific applications.
Both types effectively prevent clotting, but the choice between them may depend on specific laboratory protocols and test requirements.
Yes, K2 EDTA tubes are suitable for most hematological tests, including complete blood counts (CBC) and blood typing.
K3 EDTA tubes are often used in specialized applications where a higher concentration of potassium is needed, such as certain molecular assays.
Store EDTA tubes at room temperature (4-25°C) and avoid exposure to extreme temperatures or direct sunlight to maintain their effectiveness. It is important to check the expiration date on the tubes and avoid using expired products
