A New Separation Micro Grinder

Abstract

The invention discloses a novel separated micro grinder, which comprises a grinder body and a grinder head. The grinder body includes a grinding pestle and an unloader set in the middle of the grinding pestle. The unloader moves up and down along the grinding pestle. In the middle of the grinding pestle, a ring-shaped clamping table is fixed. The connecting rod is inserted vertically into the ring-shaped clamping table and the lower part of the connecting rod is connected to the upper edge of the ejector. A release button is set on the top of the connecting rod. Between the button and the ring card platform, the upper end of the spring is pressed against the release button, the lower end of the spring is pressed against the ring card platform, the grinder head is set on the bottom of the grinder body and the upper edge of the grinder head is connected to the lower edge of the release Close to each other, the invention improves the grinding efficiency of samples and reduces the possibility of contamination of experimental samples. The invention has simple structure, convenient operation, safe material selection and low cost.

Description

technical field [0001] The invention relates to a novel separated micro grinder, which belongs to the technical field of experimental equipment. Background technique [0002] Among the current micro-grinders, the most simple and common one is the grinding rod, which is simple in design and low in cost. It is only a single rod-shaped structure, and the rod head is a conical structure. The grinding rod can fit well with the bottom of the 1.5ML centrifuge tube, so the grinding stone often presses the sample into a lump at the bottom of the tube. However, it cannot be fully ground, and when the grinding rod is reused, it is easy to cause sample contamination if the sterilization is not complete; the other is an electric grinder, which is a separate type, but the disadvantage is that it needs to be driven by electricity. The grinder body cannot be sterilized by high-temperature and high-pressure steam, and the grinder head is a matching grinding rod, so the whole grinder is expe...

However, it cannot be fully ground, and when the grinding rod is reused, it is easy to cause sample contamination if the sterilization is not complete; the other is an electric grinder, which is a separate type, but the disadvantage is that it needs to be driven by electricity. The grinder body cannot be sterilized by high temperature and high pressure steam, and the grinder head is a matching grinding rod, so the whole grinder is expensive
