Test instrument for dissolution rate of drugs

Abstract

The invention discloses a test instrument for dissolution rate of drugs and mainly relates to the technical field of drug inspection. The test instrument comprises a base, wherein four adjusting bolts are arranged at the edge of the base; a reference block is arranged on the base; a level bubble is arranged on the reference block; a cylindrical lug boss and a heating box are arranged at the top of the base; an annular water bath box is arranged on the cylindrical lug boss in a sleeving manner; an annular cover is arranged at the top of the annular water bath box; a lifting mechanism is arranged on the cylindrical lug boss; a cylindrical shell is arranged at the top of the lifting mechanism; a driving motor is arranged at the top of the cylindrical shell; a plurality of rotating shafts are annularly arrayed on the cylindrical shell; stirring paddles are arranged at the bottom of the rotating shafts; a dissolving cup is arranged in the annular water bath box. The test instrument has the beneficial effects of reducing the interference factor of the dissolution rate test, guaranteeing the reliability of the test result, shortening the time for correcting the test instrument for dissolution rate and improving the working efficiency.

Description

technical field [0001] The invention relates to the technical field of drug testing, in particular to a drug dissolution tester. Background technique [0002] Dissolution rate refers to the speed and degree of drug dissolution from solid preparations such as tablets in a specified solvent. Dissolution rate is an important indicator of tablet quality control. At present, the dissolution tester is mostly used to test the dissolution rate of drugs. The test results of the dissolution tester are easily affected by many factors. If the instrument is not placed horizontally or the verticality of the rotating shaft is too large, the dissolution rate will increase. In order to solve this kind of interference, it is necessary to calibrate the dissolution tester with a level meter and a square before the experiment. The calibration process takes up a lot of time. The time and work efficiency are low, and the water bath tank of the existing dissolution tester is heated by a heating wi...

At present, the dissolution tester is mostly used to test the dissolution rate of drugs. The test results of the dissolution tester are easily affected by many factors. If the instrument is not placed horizontally or the verticality of the rotating shaft is too large, the dissolution rate will increase. To solve this kind of interference, it is necessary to calibrate the dissolution tester with a level meter and a square before the experiment. The calibration process takes up a lot of time. Time and work efficiency are low, and the water bath box of the existing dissolution tester is heated by a heating wire installed at the bottom. The surface of the heating wire will generate scale during long-term use, which will easily cause differences in the water temperature at different positions in the water bath box. , which in turn affects the detection results of the dissolution tester
