High-density serum separator gel is a physiologically inert gel used in the manufacture of medical testing, applied in biochemical tests, immunological tests, etc. It has the advantages of raising the serum surface, preventing material exchange between blood cells and serum, ensuring that the biochemical properties and chemical processes of the serum do not change over a long period of time, and there is no need to use special tools to transfer the serum. Precautions: 1. When using, you must wait for the blood to completely clot before centrifuging. 2. Recommended centrifugation speed: ≥ 3000 revolutions/minute 3. Recommended centrifugation time: no less than 10 minutes Packaging specifications: 25KG/barrel Shelf life: 12 months
