Description
These 3ml K2EDTA Vacutainer tubes are specifically designed for venous blood sampling, providing you with perfectly preserved, uncoagulated blood for further downstream testing.
The anticoagulant agent used in these vacutainer tubes is dipotassium EDTA salt, K2EDTA, spray dried to the inner walls of the tube with no separator. The EDTA concentration in BD Vacutainer® tubes is 1 8 mg/mL of whole blood, as recommended by the International Council Society of Haematology (ICSH) for use in haematological investigation.
Ethylenediaminetetraacetic Acid (EDTA) salts are a widely used anticoagulant preservatives used to prevent coagulation of whole blood samples and are especially effective at preserving cellular blood components. The anticoagulant mechanism of action of EDTA is the formation of complexes between the EDTA and metal ions, such as calcium, which works to inhibit the normal coagulation cascade, thereby preventing coagulation. An added advantage of using EDTA is that its anticoagulant effects are reversible.
To avoid micro-clotting, it is recommended that the EDTA tubes are mixed by inverting them 8-10 times, immediately after taking the blood sample.
These vacutainer tubes are 16mm x 100mm in size, manufactured from high quality polyethylene terephthalate (PET) and can hold a blood draw of up to 10ml. Each tube is fitted with a BD Hemogard™ cap closure, a safety-engineered closure protecting users against blood splashing and splatter through its integrated shield. This ensures the safety of users, minimising the dangers of unscreened blood mixing and prevents the contamination of samples.
