A grinding device for molecular biology experiments

Abstract

A grinding device for molecular biology experiments comprises a grinding container body and a grinding rod body, the grinding container body includes a grinding inner tank and a protective layer arranged outside the grinding inner tank, and the grinding chamber includes a first grinding chamber and a second grinding chamber, The first grinding chamber, the second grinding chamber, and the cooling medium chamber are all arranged on the grinding inner tank, and at least a part of the cooling medium chamber is arranged between the first grinding chamber and the second grinding chamber for the two to share. The grinding rod body includes a head. The handle part and the two grinding single rods connected to the head handle part, the two grinding single rods correspond to the first grinding chamber and the second grinding chamber of the grinding container body respectively, and one or all of the two grinding single rods is detachable. Through the scientific design of the grinding vessel body with multiple grinding chambers and the grinding rod body with multiple single grinding rods, the present invention obtains a single-chamber grinding and multi-chamber grinding at the same time, and has a reasonable structure, comfortable operation, smooth grinding, Stable, freeze-proof new grinding unit.

Description

technical field [0001] The invention relates to the technical field of molecular biology experiments, in particular to a grinding device for molecular biology experiments. Background technique [0002] In molecular biology experiments, grinding biological tissues is a routine operation for preparing nucleic acid samples. Electric grinder grinding and manual grinding are commonly used methods. In manual grinding, grinding containers and grinding rods are used for extrusion and tamping. Wall-breaking operations such as crushing are not as efficient as electric grinder grinding, but the operation mode is flexible, and it is also easier to observe and protect samples and perform intermediate control, so manual grinding is still a common method in laboratories.

AI Technical Summary

Problems solved by technology

[0002] In molecular biology experiments, grinding biological tissues is a routine operation for preparing samples such as nucleic acids. Both electric grinder grinding and manual grinding are commonly used methods. During manual grinding, grinding containers and grinding rods are used for extrusion and pounding. The efficiency of crushing and other wall-breaking operations is not as high as that of electric grinders, but the operation method is flexible, and it is easier to observe and protect samples and perform intermediate control. Therefore, manual grinding is still a commonly used method in laboratories.

[0003] In the case that manual grinding is still the main grinding method in the laboratory, only one sample can be ground at a time, the grinding speed is slow, and the grinding efficiency is low. At present, there is no good solution. In some well-designed research experiments In the process, it is possible that dozens or even hundreds of samples need to be ground and analyzed in the whole process. In this case, one sample is operated one by one. On the one hand, it will consume a lot of manpower and time. On the other hand, different samples grinding conditions are also difficult to maintain similar

In view of these shortcomings, at present, there is no grinding device in the market that can make a breakthrough in the grinding mode and is especially suitable for manual grinding in molecular biology experiments.
