Adopt 7-inch large LCD touch screen, easy to understand the operation.

The instrument is connected to the server through the network, connected to the LIMS system, you can choose offline and network two applications to log in the system.

The instrument system is equipped with access control rights management function, audit trail, lock screen, data backup, etc. Fully in line with the 2020 version of the “Pharmacopoeia of the People's Republic of China” and the provisions of the national industry standards and the requirements of data integrity.

There are three levels of user level management rights, with audit trail function.

With low temperature alarm (<3℃), high temperature alarm (>47℃) and water shortage protection function.

Specially designed automatic dosage device to realize synchronous dosage during paddle method experiment.

Optional micro-printer to print the experimental records (including time, temperature and rotation speed and other test data).

Optional full-data high-precision dissolution cups, each dissolution cup with 3D scanning of the certification report, high-precision dissolution cups with more accurate internal dimensions, spherical radius structure to ensure the accuracy and repeatability of the dissolution experiment. 

Instrument structure and characteristics：

1. which is convenient and fast to operate, precise to control, and friendly to human-computer interaction interface. Users can enjoy intelligent operation according to the screen prompts.

2.dissolution instrument adopts a high head structure design form; The space 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 the dissolution cup is also easy and convenient.

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

4. Audit tracking records: Multiple content and parameters for long-term preservation.

5. The design of no gap between the dissolution cup and the water tank ensures automatic center positioning. Eliminate system errors.

6. The instrument provides options for "basic test" and "program test", and the basic test function can change the test parameters at any time as needed, making it convenient for research experiments. The program testing function can execute 16 preset test programs, making it convenient for routine repetitive testing.

7. The instrument provides intelligent temperature calibration function, allowing users to easily, conveniently, and reliably complete temperature calibration and calibration through interactive operation.

8. The operation monitoring interface of the instrument provides users with 7 real-time data display windows; Real time display of temperature, real-time display of rotational speed, cumulative timing display, current waiting 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 for external printers. Print real-time test data such as time, temperature, and speed during the test process.

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

11. The instrument provides a "message board" function, which can be used to write and save text prompts or important notes for the operator taking over the shift.

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 check and automatic protection functions, and can provide various fault alarm prompts and secondary overheating protection.

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

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

17. The instrument complies with the 2025 edition of the Chinese Pharmacopoeia.
