Disposable normal-pressure/near-normal-pressure flexible reactor for laboratory

Abstract

The invention discloses a normal-pressure / near-normal-pressure cavity-shaped flexible reactor for a laboratory, which is made of a flexible material, is provided with a functional layer structure and a sealable interface, and can be used for stirring and mixing materials in the forms of rolling, extruding, rubbing and the like by using a manual tool or a motorized tool. Temperature control of materials in the reactor can be achieved through the interlayer or an externally attached heat preservation layer or heat transfer layer, light irradiation, microwave irradiation, heat conduction and the like. The reactor is particularly suitable for reactant systems such as high-solid-content materials, high-viscosity materials, non-Newtonian fluid materials and the like which are small in material liquid volume (such as milliliters and hundred milliliters) and are difficult to conventionally stir and mix, and the problems of laboratory mixing and reaction of the materials are solved. The reactor is a disposable container, has the advantages of simplicity and convenience in use, convenience in management, safety, environment friendliness, low comprehensive cost and the like compared with a conventional reactor in a laboratory, and has obvious technical and use values.

Description

technical field [0001] The invention belongs to the technical field of laboratory reactors, in particular to a disposable normal-pressure / near-normal-pressure flexible reactor for laboratories. Background technique [0002] At present, glass reactors are normal pressure / near normal pressure reactors commonly used in laboratories, such as flasks, microchannel reactors, etc. The disadvantage of this type of reactor is that the reaction device is complex, and one or more functional devices are used in conjunction with the reactor in actual operation, such as: fixtures, stirring devices, temperature control systems, and containers and instruments with specific functions. Once the device is set up, it is not easy to move, and the more functional devices occupy more space, it is also not conducive to observing the reaction; in order to have a good mixing effect, the reactor has a minimum amount of material added, which wastes resources, and the excess chemical materials increase t...

AI Technical Summary

Problems solved by technology

The disadvantage of this type of reactor is that the reaction device is complex, and one or more functional devices are used in conjunction with the reactor in actual operation, such as: fixtures, stirring devices, temperature control systems, and containers and instruments with specific functions. Once the device is set up, it is not easy to move, and the more functional devices occupy more space, it is also not conducive to observing the reaction; in order to have a good mixing effect, the reactor has a minimum amount of material added, which wastes resources, and the excess chemical materials increase the laboratory " "Three wastes"; special materials, such as high solid content materials, high viscosity materials, non-Newtonian fluid materials, etc., due to adhesion, dead ends, etc., it is difficult for conventional stirred reactors to mix materials evenly; , anaerobic and other reactions with special environmental requirements; after a reaction, the reactor needs to be cleaned with water and chemical solvents, resulting in a large amount of waste liquid; glassware is easy to break, and it is easy to cause harm to experimenters

[0003] For materials with high solid content, high viscosity, elastoplasticity, non-Newtonian fluids, etc., which are difficult to be stirred and mixed in conventional laboratory reactors, if mechanical mixing methods are used, such as kneaders, screw extrusion and other equipment, due to the operation of the equipment, the loading Due to the lower limit requirements and dead volume, it is generally above 1L, which is far beyond the experimental feeding volume of milliliters and 100 milliliters required by the laboratory. The safety level and the total amount of waste materials; the more viscous materials and equipment dead ends also increase the difficulty of cleaning mechanical equipment, generate more waste liquid, and increase the investment in "three wastes" treatment; material adhesion, insufficient mixing and equipment Dead angle and dead volume, etc., will also lead to uneven mixing of materials and insufficient reaction

[0004] In addition, for laboratory-level reaction processes that often require precise metering, insufficient material mixing will directly lead to full utilization of materials, which in turn affects the analysis of the experimental process and the stability, reliability and accuracy of experimental results

At this time, the development of a reactor with strong material applicability, high operability, safety and environmental protection, and low overall cost has become a problem of great technical significance and use value.
