Manufacturing method of tangential flow filtration system
1. The utility model relates to the field of tangential flow filtration, in particular to a tangential flow filtration system.
2. During tangential flow filtration, convection is formed between the reflux end and the replenishment end. If the liquid at the reflux end and the liquid in the sample container cannot be fully mixed, but directly enters the replenishment end, the following defects may be caused:
3. During ultrafiltration, the sample in the sample container is over concentrated locally, that is, the sample is mixed unevenly. Further, it increases the frequency of membrane blockage, ultrafiltration delay and inaccurate concentration.
4. In the filtration process, due to the uneven mixing of the replacement solution and the sample in the sample container, there is the problem of incomplete replacement of the buffer solution.
5. In order to solve the above technical problems, a tangential flow filtration system is provided. Through the mixing blade that can rotate in the storage tank and move up and down, the liquid returned by the tangential flow filtration membrane is fully mixed with the liquid in the storage tank, so as to alleviate the technical problem of uneven sample mixing in the process of tangential flow filtration.
6. In order to achieve the above purpose, the technical scheme adopted by the utility model is:
7. Tangential flow filtration system, including storage tank, pump and tangential flow filtration membrane. The bottom of the storage tank is connected with the pump through the first pipe, the pump is connected with the tangential flow filtration membrane through the second pipe, and the tangential flow filtration membrane is connected with the interior of the storage tank through the third pipe. The tangential flow filtration membrane also includes the fourth pipe. Pressure gauges are set on the first pipe and the third pipe; It also includes a mixing device arranged on the storage tank, and the mixing device includes a mixing blade that can rotate in the storage tank and move up and down.
