Description

Suspension type flow dialysis device

Technical Field

The utility model relates to a biochemical treatment device technical field especially relates to a floated mobile dialysis device.

Background

Dialysis has become one of the most convenient and commonly used separation and purification techniques in biochemical laboratories. In the preparation process of biological macromolecules, dialysis techniques are used for desalting, removing a small amount of organic solvent, removing biological micromolecular impurities, concentrating samples, restoring protein and the like. Dialysis can be accomplished by using only a dedicated semipermeable membrane as the osmotic reservoir, and the study on dialysis membranes is mature, while the study on the reservoirs containing the dialysate and the devices used for dialysis is relatively rare.

The existing laboratory generally adopts static dialysis, and biological macromolecule sample solution is put into a dialysis bag, two ends of the dialysis bag are tied, and then the dialysis bag is immersed into water or buffer solution. The biomacromolecules in the sample solution are trapped in the bag, and the salt and the micromolecular substances are continuously diffused and dialyzed out of the bag until the concentrations of the two sides inside and outside the bag reach the balance. The sample solution remaining in the dialysis bag without dialysis is called "retentate", and the solution outside the bag (membrane) is called "exudate" or "dialysate".

For dialysis of a small volume of sample, a section of glass rod with two ends being burnt into a circle or a glass tube with two sealed ends and other adjusting structures can be placed in the bag, so that the dialysis bag is sunk below the liquid level. In order to ensure that the dialysis bag sinks, the dialysis bag is additionally provided with the adjusting structure, so that the structure of the dialysis bag is complex, the cost of the dialysis bag is increased, and the dialysis bag is inconvenient to transport if the adjusting structure is made of glass materials.

Large-scale dialysis needs to process a large amount of samples, needs a large amount of buffer solution, needs a container with a large capacity for holding the dialysate, occupies a large area, needs to take out a dialysis bag when the dialysate is replaced, and generally needs to replace the buffer solution for 3-4 times (even more times), so that the buffer solution replacement process is troublesome in operation, easy to pollute and high in cost, and can not meet the processing requirements of a large amount of samples.
