Chapter 2 Introduction
The VK 7025 is designed for dissolution testing of a variety of pharmaceutical products,
including tablets, capsules, transdermal patches, and membranes. It can be configured
as USP Apparatus 1, 2, 5, or 6.
The unique design of the VK 7025 has a lower profile than existing dissolution apparatus.
The drive unit moves up and down with the touch of a key to move paddles or basket
shafts into and out of the vessels. In order to allow clear access to the vessels, the drive
unit slides back rather than continuing to move upwards. This compact design has the
evaporation covers attached to the spindle housings on the drive unit and offers
convenient access to the mechanics of the system through a hinged top cover.
The front panel displays the Method Status screen during a run, providing full information
on spindle speed, elapsed time, temperature and more. Most operating parameters are
programmable including spindle speed, test length, bath temperature, and test start
times.
The built-in Report Center Printer provides a complete report, either at pre-programmed
time intervals or on demand, of several important test parameters. Printouts are on plain
paper which will not fade or discolor over time or with exposure to chemical fumes.
