Abstract

The invention discloses a solution filtration device, which comprises a round and small cup, a filter membrane and a filtrate collecting device, wherein the filtrate collecting device is fixed on thelower part of the round and small cup, the filter membrane is arranged between the round and small cup and the filtrate collecting device, the round and small cup, the filter membrane and the filtratecollecting device jointly constitute a single filtering device which is fixed on a single fixing and collecting device. The solution filtration device is not only capable of improving the working efficiency and reducing the risk of sample confusion or contamination, but also has a wide application range and the advantage of high flux.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a solution filtration device. Background technique [0002] At this stage, filter paper blood spots are widely used in clinical testing, especially for neonatal disease screening. The method is to use special filter paper to collect blood samples, and then use instruments to cut out blood spots that meet the required diameter as experimental samples according to the experimental method, and put them into the laboratory. The blood sample is dissolved and eluted in the microwell plate used for the experiment, and the content of the target analyte in the blood film is detected to assist in disease judgment. After the analyte extraction is completed, if the microplate contains tablets, it will affect different detection items to varying degrees. Some items cause the experiment to fail and the test results cannot be obtained; some items cause cross-contamination or testing, which a...
