S-Monovette® Citrate 9NC tube is a sterile venous blood collection device containing 0.106 mol/l (3.2%) buffered sodium citrate anticoagulant intended for coagulation testing. The tube is supplied with a green membrane screw cap, paper label and is sized 65 x 13 mm (length x Ø) with a nominal sample volume of 2.9 ml. Tubes are sterile, electron-irradiation sterilised and supplied in batched packs of 50.
Bnefits
Buffered sodium citrate 0.106 mol/l (3.2%) — standard concentration for coagulation tests (e.g., PT/INR, aPTT)
Membrane screw cap provides secure, liquid-tight closure and compatibility with S-Monovette handling systems
Sterile and packaged in batched packs for traceability
IATA/ADR compliant labelling for transport
Indications
Collection of venous blood for coagulation studies and haemostasis testing where 0.106 mol/l (3.2%) citrate is indicated
Composition
Tube material: Polypropylene (PP) — transparent tube body
Anticoagulant: Buffered sodium citrate 0.106 mol/l (3.2%) (pre-dosed for 2.9 ml draw volume)
Cap/closure: High density polyethylene (HD-PE) membrane screw cap (green, EU/ISO colour coding)
Label: Paper label with appropriate fill marks and brown/green print as per product labelling
Formulation
Sterile, single-use blood collection tube with liquid anticoagulant; membrane screw cap closure and visible fill mark for correct blood:anticoagulant ratio
Pack size: 50 tubes per box (sterile, batched). Carton labelling includes lot, expiry and IFU reference — verify carton for specific catalogue number and batch details
Usage
Collect venous blood into the tube using appropriate S-Monovette collection technique or compatible devices, ensuring correct fill to the indicated fill mark to maintain specified blood:anticoagulant ratio
Mix gently by inversion immediately after collection as directed in the IFU to ensure proper anticoagulation (typically 3–5 gentle inversions; follow local lab SOP and IFU)
Process samples according to laboratory protocol for coagulation testing (centrifugation, timely testing per assay requirements)
Contraindications
Do not use if sterility of the package is compromised or packaging is damaged
Not intended for tests requiring anticoagulants other than sodium citrate (use appropriate tube type for those assays)
Adverse Effects
Risks are related to venepuncture procedure (e.g., haemorrhage, haematoma, infection) rather than the tube itself; improper fill or mixing may produce invalid test results (e.g., incorrect coagulation times)
Follow standard venepuncture precautions and local incident reporting for any adverse events
Storage Conditions
Store in original packaging in a cool, dry place away from direct sunlight
Refer to product carton and IFU for specified storage temperature range and shelf-life
Duration
Not applicable (single-use diagnostic collection tube used per venepuncture/sample)
Onset
Anticoagulation is immediate upon correct blood draw and mixing; sample suitable for coagulation analysis once properly mixed and processed per laboratory protocol
