Description
Technical Field
The invention belongs to the technical field of drug test instruments, and particularly relates to a full-automatic filter membrane changer.
Background
So far, the pharmaceutical industry has been dissolution testing by means of independent drug dissolution instruments. Samples were taken from the dissolution cup and then sent for analysis. The standard procedure is to place a sampling needle on the syringe and then place an external filter on top of the sampling probe. The purpose of this method is to filter out undissolved particles, avoid clogging syringes and tubing, etc. When the external filter is installed, the user can use the sampling needle to insert into the cuvette containing the undissolved particles to remove the sample. However, the external filter cannot filter out all small particles in a sample containing undissolved particles, resulting in clogging after a long-term use, and thus failing to obtain accurate analysis results. Experiments prove that the filter can be normally used for 6 times, so that the filter needs to be replaced by a second filter after being used for 4 times in general. A replacing step: the sample is first stored in the syringe and the user then removes the needle and attaches a second filter (gauge: 45 microns or 22 microns). After the second filter is installed, the user injects the sample into a vial or glass tube for further analysis. In most cases, the second filter (membrane filter) is used only once, in order to avoid contamination. In this case, all the second filtration is performed manually, but the manual operation is time-consuming and difficult, and the accuracy is also a problem.
