What is the difference between EDTA K2 and EDTA K3 in blood collection tubes?
EDTA K2 and EDTA K3 both act as anticoagulants, but EDTA K2 is typically used for more accurate hematology results as it preserves cell morphology better. EDTA K3 is preferred for specific automated analyzers and applications that require liquid anticoagulants for smoother blood mixing.
Are these tubes compatible with all hematology analyzers?
Yes, Siny EDTA K3 K2 Blood Collection Tubes are compatible with most standard hematology analyzers. Their precise design, accurate anticoagulant concentration, and high-quality materials ensure reliable performance across different testing instruments used in laboratories and hospitals worldwide.
What certifications do the Siny EDTA tubes have?
The Siny tubes are CE, ISO, and FDA certified, ensuring compliance with international quality and safety standards. These certifications guarantee superior product reliability, sterility, and precision suitable for global medical and laboratory applications.
