Product Overview

Siny Vacuum Blood Collection EDTA Tube Whole Blood Tube by SINY is a premium blood collection solution expertly crafted for clinical and laboratory use. These tubes are pre-filled with EDTA K2 or EDTA K3 anticoagulants that prevent blood clotting by chelating calcium ions, preserving the morphology and volume of blood cells, especially platelets, for reliable hematology testing. Available in multiple volumes ranging from 2ml to 10ml, with durable PET or glass tube options, these disposable vacuum tubes enable precise blood sampling and are compatible with direct sampling analyzers for enhanced laboratory workflow.

Produced by Ningbo Siny Medical Technology Co., Ltd, established in 2003, these tubes benefit from over two decades of manufacturing expertise, stringent quality control, and certifications including CE and ISO13485. SINY offers broad customization options for additives, labeling, and packaging to meet diverse clinical needs.

Key Features

1. Accurate Anticoagulation:

EDTA K2 or K3 works by chelating calcium ions, effectively preventing coagulation and maintaining cell integrity for precise test results.

2. PET Tube Construction:
Made from high-quality polyethylene terephthalate (PET), the tube offers excellent transparency, impact resistance, and leak-proof performance, ensuring safety during sample handling and transport.

3. Spray-Dried EDTA Coating:
The inner wall of the tube is coated with spray-dried EDTA K2 or K3, rather than a liquid form, which minimizes dilution and maintains the original blood composition for reliable test accuracy.

4. Secure Closure System:
The cap is made of medical-grade butyl rubber with a high-quality plastic shell, designed to maintain vacuum stability and prevent contamination. It also supports smooth piercing and resealing during sample processing.
