Centrifuged material layer measurements taken in an evacuated tube.

A the material layer of far-core processor is float's vacuum glass test tube or a transparent plastic test tube and a. And sending with possibly been polluted material; when detecting the small test, wherein the vacuum test tube is provided with a blood to avoid expose directly in front of the operative identification method. The test tube capable of containing of 1ml blood, and imitated of the low voltage inert gas. Layer the capacity of large, therefore the test tube and float's and allowance claim with the infrared vessels have the allowance comparing can be more loose. The material layer of each of the process, capable flow to subside to the blood plasma layer opposite and a film, therefore a battery group is stable.
