Description

Technical Field

[0001] The utility model relates to the technical field of buffer storage containers, in particular to a large-capacity sterile enzyme-free buffer storage barrel. Background Art

[0002] Buffers are commonly used and important reagents in biological and chemical experiments, as well as in related industrial production. For many biological experiments and medical applications, buffers must be sterile. For example, in cell culture experiments, any microbial contamination can cause abnormal cell growth or even death. Furthermore, in certain buffers, such as those used for nucleic acid extraction or protein research, enzymes must be avoided, as these enzymes may degrade nucleic acid or protein components in the buffer, potentially damaging experimental materials. Therefore, ensuring that buffers are sterile and enzyme-free is crucial.

[0003] Existing large-capacity buffer storage containers are mostly cylindrical. Due to their smooth surface and heavy weight, they are inconvenient to carry. Furthermore, to access the buffer, the sealed lid must be opened and a transfer container must be used, which is inconvenient. Furthermore, once the sealed lid is opened, the buffer inside the barrel comes into direct contact with the air, making it susceptible to contamination by airborne impurities. This inadequately ensures the sterility and enzyme-free nature of the buffer, affecting its quality and effectiveness. Therefore, those skilled in the art have provided a large-capacity sterile and enzyme-free buffer storage barrel to address the problems raised in the aforementioned background art.
