Instrument structure and characteristics:

1. The RC-8D adopts a high-resolution color touch screen, which is easy and fast to operate, precise in control, and has a friendly human-computer interaction interface. Users can enjoy intelligent operation according to the screen prompts.

2. The RC-8D dissolution apparatus adopts a high head structure design form; The space size between the lower edge of the machine head and the water tank is larger than that of conventional models. It is conducive to medication administration, sampling, or fluid replacement operations, and the retrieval and placement of dissolution cups are also easy and effortless.

3. System permission management: multi-level, multi-user (login method: username+password).

4. Audit tracking records: Multi content, multi parameter long-term storage.

5. The dissolution cup and water tank are designed with no gap to ensure automatic center positioning. Eliminate systematic errors.

6. The instrument provides options for "Basic Test" and "Program Test", and the basic test function can change the test parameters as needed at any time to facilitate research experiments. The program testing function can execute 16 pre-set testing programs, making it convenient for routine repetitive testing.

7. The instrument provides intelligent temperature calibration function, and users can easily, simply, and reliably complete temperature calibration and correction through interactive operation.

8. The operation monitoring interface of the instrument provides users with 7 real-time data display windows; Real time temperature display, real-time speed display, cumulative timing display, current waiting for sampling times, current "nth" sampling time, remaining time waiting for the current "nth" sampling (countdown), current "year month day", "hour minute second" display.

9. The instrument provides a standard 232 output interface that can be connected to an external printer. Print real-time test data such as time, temperature, and speed during the testing process.

10. The instrument provides two operation interfaces in Chinese and English, with one click switching.

11. The instrument provides a "message board" function, which can write and save text prompts or important notes for the incoming operators on the message board.

12. The instrument provides timed shutdown and timed automatic preheating functions.

13. The instrument provides editing functions for Chinese characters, numbers, and English. It can provide data such as test number, sample name, test parameters, and test method for printing output.

14. It has self checking and automatic protection functions, and can provide various fault alarm prompts and secondary overheating protection.

15. The RC-8D has a built-in electric lifting structure for the machine head, which not only has a beautiful appearance, but also avoids oxidation and corrosion of the lifting machinery exposed to the air, and reduces motion noise.

16. A dissolution cup lid to prevent evaporation of the dissolution medium.

17. The instrument complies with the 2020 edition of the Chinese Pharmacopoeia

18. The instrument complies with the "Guidelines for Mechanical Validation of Drug Dissolution Instruments"
