Multifunctional homogenizer

The invention discloses a multifunctional homogenizer comprising a homogenizing tube and a homogenizing rod inserted in the homogenizing tube. The wall thickness of the bottom of the homogenizing tubeis larger than the wall thickness of the side wall. The homogenizing tube comprises an anti-overflow chamber, a coarse grinding chamber and a fine grinding chamber communicating with one another andhaving shapes of large upper part and small lower part; a coarse and fine mixing positioning table is arranged between the coarse grinding chamber and the fine grinding chamber; the anti-overflow chamber is in the shape of a waist drum; the homogenizing rod comprises a rod body, a splash-proof cover and a grinding head arranged up and down; the cross-sectional area of the splash-proof cover is smaller than an opening at the top of the anti-overflow chamber and larger than the outer diameter of the grinding head; the grinding head comprises a coarse grinding section, a coarse and fine mixing transfer face and a fine grinding section corresponding to the coarse grinding cavity, the coarse and fine mixing positioning table and the fine grinding cavity respectively. According to the characteristics of samples and experimental requirements, more animal and plant tissues can be grounded roughly and mixed and grounded roughly and finely under required temperature conditions, and a small amount of micro-organisms can also be ground finely so as to quickly achieve complete homogenization effect of various samples, ideal homogenizing effect and small sample loss.
