Product Overview

Siny Manufacturer Medical Supplies EDTA K2 K3 Tube by SINY is a premium vacuum blood collection tube designed for reliable anticoagulation in clinical hematology. Featuring EDTA K2 or K3 as the anticoagulant, the tubes prevent blood clotting by chelating calcium ions, preserving blood cell integrity, particularly platelets. Available in various volumes and made from high-quality glass or PET, these tubes ensure consistent sample quality, enhancing lab testing accuracy. Manufactured under strict ISO13485 and CE-certified processes in a Class 100,000 cleanroom, they meet global medical standards for safety and performance.

Operating since 2003, Ningbo Siny Medical Technology Co., Ltd specializes in medical consumables, exporting to over 80 countries. Their expertise supports customization for additives, labeling, and packaging. These tubes are widely used for CBC, blood typing, ESR, and molecular diagnostics.

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.
