Product Overview
EDTA-K2 and EDTA-K3 vacuum blood collection tubes are essential tools in clinical diagnostics. These lavender-top tubes contain ethylenediaminetetraacetic acid (EDTA) salts—K2 (dipotassium) or K3 (tripotassium)—which act as anticoagulants by chelating calcium ions, preventing blood clotting. Ideal for hematology and molecular testing, they ensure sample integrity for a wide range of applications, including Complete Blood Counts (CBC), blood typing, and DNA/RNA extraction.
Key Features
- Anticoagulant Additive: Contains K2 EDTA (typically spray-dried or liquid form) to effectively prevent clotting while maintaining cellular integrity.
- Material Construction: Made from medical-grade PP or PET, which is virtually unbreakable, highly transparent, and lightweight for ease of handling.
- Capacity and Design: 2ml volume with clear graduations for accurate measurement; features a smooth inner surface to minimize cell damage and hemolysis, leak-proof rubber stopper, and sometimes an integrated scoop for easier micro blood collection.
- Sterility and Safety: Sterilized via gamma irradiation or electron beam (EB), pyrogen-free, and often CE/ISO13485 certified; single-use disposable design with tamper-evident seals.
- Shelf Life: Typically up to 2 years, ensuring long-term usability.
