Frequently Asked Questions

Q: What is the USP standard for disintegration testing?

A: Disintegration testing is governed by USP <701> (tablets and capsules) and ChP 0921. The test measures the time for a dosage form to break into particles small enough to pass through a specified mesh screen under simulated GI conditions. USP <701> requires testing in water or simulated gastric fluid at 37°C ± 2°C, with a reciprocating basket assembly. Huanghai LB-series testers are engineered to meet these parameters, with temperature-controlled water baths maintaining ±0.5°C accuracy.

Q: What is the difference between the LB-2D and LB-3D disintegration testers?

A: The LB-2D is a 2-station tester with a touchscreen interface—suited for small labs or single-product testing. The LB-3D adds a third station, enabling three simultaneous product tests, and includes an audit trail and data management system for GMP compliance. Choose LB-2D for budget-constrained or low-throughput environments; upgrade to LB-3D when your lab handles multiple formulations simultaneously or requires traceable electronic records for regulatory submissions.

Q: How does disintegration testing differ from dissolution testing?

A: Disintegration measures whether a dosage form physically breaks apart within a specified time—it does not measure how much API is released. Dissolution (USP <711>) measures the rate and extent of API release into solution, which directly correlates with bioavailability. Disintegration is faster (typically 5–30 minutes) and is used as a routine in-process check; dissolution is the definitive QC test for bioavailability prediction. Many tablets that disintegrate quickly still have poor dissolution if the API is poorly soluble—disintegration alone is not sufficient for bioavailability assessment.

Q: Can the disintegration tester be used for suppositories or capsules?

A: Yes. The LB-series testers support both tablet and capsule disintegration per USP <701>. For suppositories, the method differs—disintegration is measured using the melting time method (ChP 融变时限), which requires a different instrument: the RBY-N Melting Time Tester. The RBY-N provides three parallel test units with adjustable rotation frequency, suitable for lipid-based suppository matrices. For complete lab capability, pair the LB-3D with the RBY-N to cover solid oral and rectal dosage forms.
