Rapid manual sample grinding device

Abstract

The invention discloses a rapid manual sample grinding device. The rapid manual sample grinding device comprises a mortar with a stirring device and a collector arranged below the mortar, wherein a feeding port is formed in the top of the mortar, the bottom of the mortar communicates with the collector, and a filter screen is arranged at the bottom of the mortar. The rapid manual sample grinding device further comprises a mortar cover used for sealing the feeding port. According to the rapid manual sample grinding device, a sample can be effectively prevented from splashing, the sample utilization rate is increased, and resources are saved, especially for rare precious samples; and in addition, in the grinding process, materials adhering to the inner wall of the mortar can be cleaned, and the problem that sample residues and internal pollution are caused due to the fact that the grinding materials adhere to the mortar for a long time can be effectively solved. The rapid manual sample grinding device is simple in structure, convenient to operate and high in grinding efficiency, has strong practicability and operability, and has a very wide application prospect.

Description

technical field [0001] The invention belongs to the field of biological material grinding tools, in particular to a fast manual grinding sample device. Background technique [0002] In laboratories, mortars and pulverizers are commonly used for sample grinding. Although the pulverizer can grind the sample very finely, due to the disadvantages of limited power supply, high noise, and troublesome cleaning, a mortar is often used for some samples that are not hard and require frequent grinding. A mortar usually consists of a mortar and pestle. Commonly used are porcelain products, but also made of glass, stainless steel, agate, and alumina materials. The mortar is used to grind solid substances or mix powdery solids, and its specifications are expressed by the size of the caliber. A mortar is usually a small bowl-shaped vessel in which substances are pounded or ground with a pestle. [0003] At present, the mortars we usually use often have problems such as sample splashing...

AI Technical Summary

Problems solved by technology

[0003] At present, the mortars we usually use often have problems such as sample splashing, insufficient grinding, sample transfer loss, repeated use of samples inside the mortar body, time-consuming and laborious operations, etc., resulting in waste of samples and deviations in test results, especially It is the continuous grinding of different samples, and the pestle is easy to wear the skin of the palm of the tester, which brings a lot of inconvenience
