Introduction
The Reciprocating Dissolution Tester ERD-37 is a versatile instrument designed for dissolution testing according to USP Apparatus 3 and 7. This apparatus is ideal for the release profiling of extended-release dosage forms. It simulates the conditions of the gastrointestinal tract by moving the sample through rows of media with different pH levels.
Product Overview
This instrument provides an efficient solution for testing complex pharmaceutical formulations. The Reciprocating Dissolution Tester ERD-37 features interchangeable vessel and row configurations, allowing for tests in 50ml, 100ml, 300ml, and 1000ml volumes. This provides the flexibility to meet the requirements of both USP 3 and 7 methods. Operation is simplified by a 3.5-inch touch screen, which allows users to program up to 20 protocols. This tester is a reliable tool for drug development and quality control.

Frequently Asked Questions (FAQ)
1. What is the Reciprocating Dissolution Tester ERD-37 used for?
It is used to test the dissolution rate of drugs, particularly extended-release products, by moving them through media of different pH levels per USP 3 and 7 methods.
2. What is the difference between USP Apparatus 3 and 7?
USP 3 (Reciprocating Cylinder) is often used for tablets, while USP 7 (Reciprocating Holder) is designed for dosage forms like transdermal patches. The ERD-37 supports both methods.
3. Can the Reciprocating Dissolution Tester ERD-37 automate tests?
Yes, you can program up to 20 test protocols, automating the change between media rows, dip rates, and test times.
4. Is the instrument easy to operate?
Yes, it features a 3.5-inch touch screen with a graphical interface that makes programming and monitoring tests straightforward.
5. What vessel configurations are available?
The Reciprocating Dissolution Tester ERD-37 is very flexible, supporting configurations for 50ml, 100ml, 300ml, and 1000ml vessels to meet various testing needs.
