S-Monovette® EDTA K3E 2.7 ml tube is a sterile, single-use venous blood collection tube containing K3-EDTA anticoagulant, designed for haematology, full-blood and plasma analysis. The tube has a membrane screw cap (red / colour-coded EU) and a polypropylene body. It is supplied in batches of 50 per pack and sterilised by electron irradiation, complying with IVD and transport standards (IATA/ADR). :contentReference[oaicite:0]{index=0}
Bnefits
Pre-dosed K3-EDTA anticoagulant (1.6 mg/ml blood) ensures reliable anticoagulation for haematology and plasma-based assays. :contentReference[oaicite:1]{index=1}
Membrane screw cap closure ensures a liquid-tight seal and maintains sterility and sample integrity. :contentReference[oaicite:2]{index=2}
Sterile, single-use and CE-marked IVD product with standardised volume and geometry (66 mm x 11 mm) for compatibility with laboratory automation. :contentReference[oaicite:3]{index=3}
Batch packaging (50 tubes) allows laboratories to manage inventory and traceability efficiently. :contentReference[oaicite:4]{index=4}
Indications
Collection of venous whole blood for haematology (e.g. full blood count), plasma preparation, and other EDTA-based analyses requiring anticoagulated blood.
Composition
Tube body: Polypropylene (PP) – transparent
Cap / closure: High-density polyethylene (HD-PE) membrane screw cap (colour-coded red per EU standard).
Anticoagulant additive: Tripotassium EDTA (K3-EDTA), concentration 1.6 mg EDTA per ml of blood. :contentReference[oaicite:5]{index=5}
Formulation
Sterile, single-use collection tube with pre-dosed liquid anticoagulant and fill-mark for correct blood draw volume; membrane screw-cap closure; fill volume 2.7 ml; dimensions 66 mm length (without cap) × 11 mm internal diameter. :contentReference[oaicite:6]{index=6}
Collect venous blood into the tube up to the indicated fill-mark to maintain correct blood:anticoagulant ratio. :contentReference[oaicite:8]{index=8}
Immediately after collection, gently invert the tube to mix blood with EDTA anticoagulant to prevent clotting, as per manufacturer’s instructions for use. :contentReference[oaicite:9]{index=9}
Process samples according to laboratory protocol (e.g. for haematology or plasma-based assays). Do not reuse tube — single-use only, dispose per biohazard / local regulation after use.
Contraindications
Do not use if the sterile packaging is damaged or expired.
Not suitable for tests requiring serum or coagulation (use appropriate tube type instead).
Adverse Effects
Risks are associated with venepuncture procedure (e.g. bleeding, haemolysis, infection) rather than the tube; incorrect blood:anticoagulant ratio or improper mixing may lead to unreliable test results.
Storage Conditions
Store in original packaging in a cool, dry place protected from direct sunlight, as per manufacturer recommendations for IVD products. (user IFU must be consulted for exact storage temperature and shelf-life)
Duration
Not applicable (single-use diagnostic device)
Onset
Anticoagulation effect is immediate upon mixing blood with EDTA inside the tube; sample remains liquid until processed. (As per product specification) :contentReference[oaicite:10]{index=10}
