All Huanghai RCZ-series dissolution testers are designed to comply with USP \u0026lt;711\u0026gt; paddle and basket methods. For international market access, verify which pharmacopoeia your target regulatory body recognizes.\"}},{\"@type\":\"Question\",\"name\":\"How many dissolution channels do I need for a QC lab?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Channel selection depends on batch size and throughput. A 6-channel tester suits small-volume labs. The 8-channel RCZ-8N accommodates USP \u0026lt;711\u0026gt; 6-vessel runs with 2 spares — standard for routine QC. A 12-channel tester is ideal for high-throughput labs running two products simultaneously.

The RCZ-8A supports connection to the RCZ-QY8 automated sampling system. The RCZ-8N features simultaneous dosing across all 8 channels and is the recommended entry point for regulated QC labs.
