Description

Technical Field

[0001] The utility model relates to the technical field of detection instruments, in particular to a centrifuge tube for detection. Background Art

[0002] Blood tests are often required for clinical examinations. Blood tests can be divided into general tests, laboratory tests for hemolytic anemia, bone marrow cytology tests, blood typing and cross-matching tests, which can detect the hematological signs of common blood diseases. Blood tests use cell sieves and centrifuge tubes. Cell sieves are generally used for impurity filtration, cell dispersion, sample separation, etc.
