Metal box type micro-test tube stand

Abstract

The invention provides a metal box type micro-test tube stand, which consists of a shelf, a base and test tube sleeves, wherein the shelf is in nested connection with the base; and the test tube sleeves which are arranged in a matrix mode are arranged on the shelf. In the metal box type micro-test tube stand, ice water bath and the micro-test tube stand are combined, so the cooling surfaces of micro-test tubes are improved to a maximum limit, the quick cooling condition is provided, the cooling effect is improved, and heat preservation time is prolonged. The metal box type micro-test tube stand is reasonable in design, easy and convenient to manufacture and low in cost, experimental operation is simplified, the requirement on experimental environment is improved, the safety and accuracy of tests are ensured, experimental loss is reduced, the experimental efficiency is improved, and the requirement of low-temperature environment in molecular biology experiments can be met.

Description

technical field [0001] The invention relates to the fields of molecular biology experiments and molecular medicine experiment equipment, in particular to a metal box-type micro test tube stand (microtubule stand). technical background [0002] Microtubule (miniature eppendorf tube) is widely used in biological experiments to carry out experimental operations on DNA and RNA. Simple plastic microtubule stands are widely used in domestic laboratories, although they can also meet the basic experimental requirements, but they are not suitable for long-term use and temperature-changing operations such as ice-water baths, and the operation methods are cumbersome. At the same time, there are also metal micro test tube racks on the market, but there are some deficiencies more or less. For example: (1) The simple plastic microtubule stand is too light in material and poor in stability, and the experimental stand (stand) often falls over due to unstable center of gravity and affects t...

AI Technical Summary

Problems solved by technology

For example: (1) The simple plastic microtubule stand is too light in material and poor in stability, and the experimental stand (stand) often falls over due to unstable center of gravity and affects the experimental operation; (2) The plastic microtubule stand is too light in quality It also makes it easy to be accidentally touched, misplaced, etc., resulting in experimental errors such as loss and falling, which seriously affects the progress of the experiment and the safety of the experiment; (3) The strength of the plastic material is too low, and it often deforms after undergoing temperature-changing operations such as ice-water baths. Seriously affect the future use, it can be seen that its reusability is not high; (4) due to its material limitation, the plastic micro test tube rack is prone to aging, cracks, deformation, etc., as the use time and frequency increase, which affects the use of the experiment. Increased the difficulty of operation which is seriously unnecessary; (5) The currently used plastic test tube rack has no corresponding numbering position, and its material is not convenient for writing and sticking sticky notes, which is inconvenient for the use of a large number of samples; (6) The existing metal Material Micro test tube rack adopts solid design, heavy volume, poor thermal conductivity, high cost of raw materials, difficult transportation
