Chapter 1: Introduction
Operation Manual: Evolution Series
The Evolution System utilizes solid-state semiconductor devices. It is
important that the humidity level be kept at or above 30% relative humidity,
to minimize the risk of damage to control circuits caused by static discharge.
Air Quality Considerations
Distek dissolution systems are designed to be operated in a lab environment that
has no visible dust problem, and with organic solvent vapor levels as low as
possible. Operation is not recommended in dusty lab environments, or in labs with
significant chlorinated or reactive solvent vapor levels. These dust or vapor levels
may have serious effects on system components. Absorption of vapors into
dissolution media may bias test results. Some dissolution tests may require
dissolution and drug release media prepared from USP quality water. Absorbed
vapors may cause difficulty in complying with USP requirements.
