Key Features & Attributes

1.100% No Additive Purity:​ Contains absolutely no anticoagulants, clot activators, or separating gels, ensuring completely natural blood coagulation for pure serum extraction.

2.Natural Clotting Process:​ Designed to allow whole blood to clot naturally (typically within 30-60 minutes) before centrifugation, preserving the original physicochemical properties of the serum.

3.Ultra-Smooth Interior:​ The inner wall is specially treated for extreme smoothness, preventing platelet adhesion, hemolysis, and fibrin sticking to ensure maximum serum yield.

4.Precision Vacuum Aspiration:​ Pre-calibrated negative pressure ensures accurate, automatic blood draw (e.g., 3ml, 5ml, 6ml), minimizing manual errors and preventing external contamination.

5.Secure Red Cap Closure:​ Features a ribbed red cap with a high-quality black butyl rubber stopper, providing a leak-proof, airtight seal for safe transport and handling.
