Mds-2008 drug dissolution sampling system Introduction: Dissolution workstation mds-2008 is a fully automatic drug dissolution test device composed of a drug dissolution instrument mds-2008ds and an automatic sampler mds-2008s. The 8-channel imported injection pump realizes high-precision automatic dissolution, sampling, replenishment, dilution and other tests. The indicators of the instrument are excellent, and the performance parameters far meet the mechanical verification guidance of Chinese Pharmacopoeia, United States Pharmacopoeia and drug dissolution instrument Principles and other domestic and foreign regulations and standards. characteristic: 1. It can be compatible with basket method, paddle method, small cup method, paddle butterfly method and rotary cylinder method at the same time; 2. The dissolution cup can be switched by software to realize isothermal liquid replenishment 3. The stirring shaft is designed in sections, and the basket (paddle) only needs to be replaced when the dissolution method is switched, and it is not necessary to manually adjust the height of the positioning basket (paddle), so as to quickly realize the dissolution method switching; when switching the small cup method, it only needs to adjust the dissolution cup and sampling needle. 4. Photosensitive lighting with white light and red light, brightness can be adjusted in three levels. When photosensitive drug dissolves out, turn off environmental lighting and turn on red light lighting. 5. Single dosing system can realize synchronous dosing or sequential dosing, and the interval time of sequential dosing can be set. 6. The water bath system is square integrated with arc angle water tank, which is easy to clean; the bottom drainage can be completely emptied; the ceramic heating pipe heating is safe and reliable, with over temperature and water shortage alarm. 7. Automatic sampling: realize on / off line sampling, including moistening, filling, dropping, sampling, refilling, emptying, cleaning and dilution, all of which can be operated offline 8. Sampling quantity: the automatic sampling volume is 0.2-15ml, and the sampling times are 1-16; when the double sample sampling is selected, the maximum sampling quantity is doubled and the sampling times are halved 9. Sampling accuracy: with high-precision injection pump, the sampling accuracy of 0.8% can be achieved when 10ml sampling; the suction stop time of injection pump can be set to solve the sampling deviation caused by different viscosity of solvent. 10. Automatic sample in and out: the sample tray can automatically enter and exit when the experiment is not carried out or the sampling interval is not conducted, and the sampling needle is automatically positioned. When it can be used, it is indicated by green light, otherwise it is red. With tray in place detection, there will be an alarm if the sampling stage is not in place, and no detection is conducted within the sampling interval. 11. Liquid level tank: it is divided into waste liquid tank, recharge tank, dilution tank and cleaning tank. The low noise diaphragm pump can realize automatic pump in and pump out. If necessary, it can realize isothermal liquid supplement, accurate dilution and automatic cleaning. 12. Sample container: 15ml test tube or 1.5ml liquid phase bottle can be selected with puncture function. Technical parameters: Heating range of water bath: room temperature - 45.0 ℃ Temperature resolution: 0.1 ℃ Temperature control accuracy: ≤± 0.2 ℃ Stirring speed range: 25.0-250.0rpm Speed resolution: 0.1 rpm Speed accuracy: ≤ ± 0.5rpm Single sampling volume: 0.2-15ml (single); 0.4-30ml (double) Sampling times: 1-16 times (single); 1-8 times (double) Sampling accuracy: ≤ 0.8% (10ml sampling)
