Frequently Asked Questions

What does USP <701> require of a disintegration apparatus?
A basket-rack assembly moving 29–32 cycles per minute through 53–57 mm in immersion fluid held at 37 ± 2 °C. LB-2D runs at 30–32 strokes/min, inside this window. LB-3D is specified at 25–35 strokes/min, so confirm the frequency it is set to for your method. Both follow ChP 0921 and Ph. Eur. 2.9.1.

What is the difference between LB-2D and LB-3D?
LB-2D has 2 stations, 30–32 strokes/min, up to 15 preset reminders, and RS232 / USB output. LB-3D has 3 stations, 25–35 strokes/min, up to 100 timed checkpoints, 3-level user management and an audit trail.

How does disintegration testing differ from dissolution testing?
Disintegration checks how quickly a tablet or capsule breaks up in fluid; dissolution measures how much drug goes into solution over time. Many labs run both.

Is the end point detected automatically?
No. As the pharmacopoeia requires, the operator judges complete disintegration visually; the tester signals each preset checkpoint so the operator does not need to watch continuously.
