Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a vacuum filtration device. Background Art

[0002] When a vacuum filtration device is filtering, a storage container is generally provided to store the buffer solution. Traditional storage containers are usually triangular flasks, but due to their small capacity, triangular flasks need to be disassembled many times during operation, making the entire operation very troublesome.

The experiment can be continued only after the corresponding reagent bottle or storage bottle is replaced. The entire replacement process will cause interruptions in the experiment, which will increase the overall operation time of the experiment and reduce the experimental efficiency.
