Introduction
The QY-8K/12K Dissolution Sampling System is a new instrument designed in accordance with the requirements of the Chinese Pharmacopoeia and the United States Pharmacopoeia. They are patented products, test instruments that meet the quality consistency evaluation of generic drugs.
Main Features
●High resolution color touch screen
●Built-in printer
●Fingerprint recognition
●Using precision glass syringe as sampling power
●Using 12 channel high precision, high chemical stability valve body
●High chemical stability PTFE pipeline has excellent anti-adsorption function
●Filter infiltration technology before test to reduce adsorption
●Sampler’s liquid return circulation technology and pipe emptying technology after sampling avoid cross contamination
●Has the same amount of isothermal rehydration function
●With distribution, dilution function
●The intelligent sampler has 12 channels of independent piping system to meet the requirements of the dissolution test for blanks and chemical reference standard
●Sampling double-stage filtration, primary filtration is a columnar filter head with a pore size of 10 µm, and secondary filtration can choose a ɸ25mm injection filter with 0.8 µm/0.45 µm/0.22 µm pore diameter or no filtration
●15-bit test tube rack for up to 120 test tubes
●Sampling tubes with a silicone cap to prevent evaporation and contamination of the sample
●Color touch screen, menu prompts, easy to operate
●Can be run online with the dissolution apparatus
●Ampoule collection device (optional)
