약전에 의한 용출법 Apparatus 1 Used for Tablets, Capsules, especially when the media is changed during the test run Apparatus 2 Standard Apparatus, used for solid dosage forms Apparatus 3 Bio. Diss: Used when the medium and the p. H is changed continuously Apparatus 4 Used for lipophilic solid dosage forms suppositories and soft capsules
Apparatus 5 Disks and Extraction cells are used to test transdermal patches. Apparatus 6 The Rotating cylinder is used to Test Transdermal patches. PTSWO: Special Tester for Suppositories, Soft Gels and similar products
탈기, 용매의 제조 • • • “The United States Pharmacopoeia (USP)” recognises that dissolved gases in the Dissolution Media may affect Dissolution Test Results and recommends that gases should be removed before the test is performed” (USP 23/NF 18) Prepared Medium to reproducible standards USP prescription of : Heating, Circulating and Vacuum The Temperature of the Media must be in the range of 37 +/- 0, 5 °C
탈기의 중요성 Particle with associated air bubble. The dissolution process is highly influenced.
Media preparation system
PT-DDS 4
용출기의 구성 실례 1. Auto sampling system 2. Flow through cell
3. On-line UV analyze 4. On-line LC analyze
Pharma test 용출기의 우수점 • Vibration absorber
• Drawer • Staggered Start • PHARMA TEST offers a staggered start feature since more than 28 years now. • Stirrer clamp screw
• Stirrer drive • Built-in Printer • A built-in printing center which will print a Test Log (speed, temperature, sampling sequence, detected errors) but also a PQ slip which can be used to record the Qualification Results of the Dissolution Bath
