At a glance: The Huanghai RCZ-8N is an 8-vessel intelligent dissolution tester from Huanghai Pharmaceutical Instruments (Shanghai, since 1978), built to keep routine dissolution runs simple, consistent and on record. Vessels and shafts centre automatically, all tablets can be dosed at the same moment, and built-in data integrity features record every run. IQ/OQ document templates are provided; on-site validation is performed by the end user. It runs USP Apparatus 1 (basket) and 2 (paddle) per USP <711>, ChP 0931 and Ph. Eur. 2.9.3.
What the Huanghai RCZ-8N does for your lab
- Automatic vessel and shaft centring. Less set-up time and fewer alignment differences between runs.
- Synchronised dosing in one action. Manual synchronised dosing puts all tablets into the medium at the same moment, so every vessel starts together.
- Scheduled pre-heating. Set a start time and the bath is at temperature when you arrive; a 24-hour reservation timer covers the working day.
- Protected, calibrated temperature. Dual over-temperature protection and a temperature calibration function protect the sample.
- Sample information on the instrument. Sample details are stored for reuse, so repeat tests start faster.
- Built-in data integrity. Password login, three permission levels (Admin, Power User, User), audit trail, data backup and USB export or printing keep every run traceable. The instrument is designed with features that support a 21 CFR Part 11 workflow.
- Sealed anti-evaporation covers. Less medium is lost on long runs.
- Quick-connect water circuit. Water-circulation pipework with medical-grade quick connectors.

Frequently Asked Questions
Which pharmacopoeia methods does this dissolution tester follow?
USP <711> Apparatus 1 (basket) and Apparatus 2 (paddle), ChP 0931 and Ph. Eur. 2.9.3. The 10–300 RPM speed range covers the usual 50 RPM paddle and 100 RPM basket settings.
How many vessels does a QC lab need?
USP <711> tests 6 units per stage, so 6 vessels (RCZ-6N) run a full stage at once.
Does it support data-integrity requirements?
Yes. It has 3-level user management (Admin / Power User / User), an audit trail recording operator, date-time and event type, test data query, USB export and RS232 printing. It is designed with features that support a 21 CFR Part 11 workflow.
What options are available for light-sensitive drugs and automation?
Amber glass vessels of the same 1,000 ml size can replace clear vessels for photosensitive APIs. For automated multi-point sampling, see the RCZ-8A, which pairs with the ZQY-8A sampler as the RCZ-QY8 system.
Does the Huanghai RCZ-8N dose all tablets at the same time?
Yes. Manual synchronised dosing drops all tablets into the medium at the same moment, so every vessel starts together.
Does it centre the vessels automatically?
Yes. Vessels and shafts centre automatically, which makes set-up faster and more repeatable. Sealed anti-evaporation covers reduce medium loss during long runs.
Can I schedule heating in advance?
Yes. A reservation timer of up to 24 hours starts heating at the time you set, so the bath is ready when you arrive.
