Abstract

The invention relates to a full-automatic filter membrane replacer which comprises a rack, a filter tray, a tray guide rail, a tray conveying mechanism, a lifting driving mechanism, an upper transverse frame, a lower transverse frame and a tray sliding groove, a plurality of filters are sequentially arranged on the filter tray, an operation plate is horizontally arranged in the middle of the rack,a plurality of through holes are formed in the operation plate, a tray guide rail is arranged at one end of each through hole in the operation plate, a tray conveying mechanism and a lifting drivingmechanism are arranged on the two sides of each tray guide rail respectively, the tray conveying mechanisms push the filter trays below the tray guide rails to the through holes in the operation plate, the lifting driving mechanisms are located at the upper ends and the lower ends of the through holes, the upper end and the lower end of the lifting driving mechanism are connected with the upper transverse frame and the lower transverse frame correspondingly and drive the upper transverse frame and the lower transverse frame to ascend and descend correspondingly, full-automatic replacement of the filter is achieved, the replacement efficiency of the filter is greatly improved, and the accuracy is high.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical testing instruments, and in particular relates to a fully automatic filter membrane changer. Background technique [0002] So far, the pharmaceutical industry has performed dissolution testing with stand-alone drug dissolution apparatus. Samples are taken from the dissolution vessel before being sent for analysis. The standard procedure is to place a sampling needle on the syringe and 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 take out the sample by putting it into the solution cup containing the undissolved particles. However, the external filter cannot filter out all the small particles in the sample containing undissolved particles, resulting in clogging after long-term use, making it impo...
