K2 and K3 EDTA Tubes: Advanced Solutions for the Laboratory
FL Medical’s K2 and K3 EDTA tubes are a key reference point for blood collection and preservation in diagnostic settings. These devices are designed to prevent blood coagulation during the analysis process and contain EDTA (ethylenediaminetetraacetic acid), an anticoagulant that binds calcium ions, thereby preventing clot formation. The difference between the two types of tubes is in the form of EDTA salt used: K2 tubes contain dipotassium salt (K2-EDTA), while K3 tubes contain tripotassium salt (K3-EDTA). Both are used in a variety of diagnostic tests, including complete blood counts (CBC), white blood cell counts, and genetic analyses.

Stability and Safety: The Advantages of K2 and K3 EDTA Tubes
K2 and K3 EDTA tubes offer numerous benefits in laboratory settings. K2-EDTA ensures better preservation of cellular morphology, making these tubes ideal for complete blood counts (CBC) and detailed blood cell analysis. At the same time, K3 EDTA tubes, while offering comparable anticoagulation performance, are more commonly used for routine laboratory testing.
Another key advantage is sample stability: both tubes maintain sample quality for up to 24 hours at room temperature, preventing degradation of cellular components.
Additionally, the airtight cap seal provides extra protection against contamination, enhancing both the safety and accuracy of test results.
Quality and Safety: The Advantages of K2 and K3 EDTA Tubes
FL Medical’s K2 and K3 EDTA tubes stand out for their use of high-quality materials, such as PET (polyethylene terephthalate), which provides excellent transparency and durability.
These features allow for optimal sample visibility and reduce the risk of breakage during handling. The caps, with their leak proof, ensure sample protection from potential leaks or contamination, maintaining integrity over an extended period.
Thanks to strict compliance with international quality and safety standards, FL Medical tubes are the preferred choice of clinical and diagnostic laboratories, meeting the demands for efficiency, reliability, and safety.
