Introduction
The ERD-07 Reciprocating Dissolution Tester is a specialized apparatus for testing extended-release products according to USP 3 and 7. This tester uses a reciprocating motion to move samples through multiple dissolution media. With its 9-row configuration, it offers extended pH profiling capabilities, accurately simulating gastrointestinal transit conditions.
Product Overview
This instrument is designed for the automated testing of complex dissolution profiles. The ERD-07 allows users to program detailed protocols via its touch screen interface. The use of nine vessel rows enables a more granular simulation of pH changes, which is critical for modified-release dosage forms. Parameters like dip rate, hold time, and drain time are all programmable for each row. The ERD-07 Reciprocating Dissolution Tester is a powerful tool for pharmaceutical development labs.

Frequently Asked Questions (FAQ)
1. What is the ERD-07 Reciprocating Dissolution Tester used for?
It is used to test the dissolution of extended-release dosage forms by moving them through up to nine different pH media, in compliance with USP Apparatus 3 and 7.
2. What is the main benefit of having 9 rows of vessels?
Having nine rows allows for a more detailed and accurate simulation of the changing pH conditions in the gastrointestinal tract, which is critical for modified-release drugs.
3. Is the ERD-07 compliant with pharmacopeial standards?
Yes, it is designed to meet the current specifications for USP Apparatus 3 (Reciprocating Cylinder) and USP Apparatus 7 (Reciprocating Holder).
4. Can I program different dip rates for each row?
Yes, you can program the dip rate (from 5 to 50 dpm), hold time, and drain time independently for each of the nine rows.
5. What vessels are compatible with the ERD-07 Reciprocating Dissolution Tester?
The standard model comes with 50ml vessels. Optional accessories are available for 100ml, 300ml, and 1000ml vessels to meet different testing requirements.
