The Teledyne LABS​​ 14-vessel CD14 Comparative Dissolution Tester runs two methods simultaneously or independently—ideal for bioequivalence studies of generic vs. innovator drug formulations. The 14 stirring positions allow for 6+1 or 12+2 configurations for improved workload efficiency in R&D, formulations, QC, and stability-test labs. With digital temperature​ probes at 12 positions the CD14 comparative dissolution tester is able to test two different formulations with separate settings for every parameter under the same temperature conditions.

Fast, Powerful Computer Control

The CD14 is controlled by a fast, powerful computer built into the color touch screen display mounted to the drive head. The adjustable tilt angle accommodates operators of different heights while the Linux-based operating system with its own SQL database responds instantly to user input. The highly durable resistive touch screen works with gloves on or off. An easy-to-use interface includes context-sensitive help; logs for events, errors, test reports, test history, and service; rapid programming of new methods; ability to search database by any combination of fields; import/export including full system backup; programmable alarms for automatic power-on and warm-up; countdown to sampling points; tools including full system diagnostics; and more.

English, Chinese, Korean, and Spanish are standard on CD14 testers

Firmware is available in English, Chinese, Korean and Spanish languages. The firmware incorporates these languages in the user interface and printed reports.

Serialized Components

All critical components of the CD14 are identified by unique serial numbers traceable to the factory level including the spin-shafts installed into the drive head, all baskets and paddles, and all dissolution vessels. The part number and serial number of each vessel are laser-engraved into the top of the vessel rim in large, easy-to-read type, such that breakage of the glass will not destroy identifying information. The on-board database of the CD14 stores the system configuration including the se​rial numbers of all vessels, paddles, and baskets, and the position into which each item is installed.

Precision Vessel Centering System

Each dissolution vessel installs into an adjustable bracket attached to the vessel plate. These vessel-centering brackets allow precision adjustments to the dissolution vessel’s position in relation to the spin-shaft and any apparatus attached to it. The system allows fast and easy vessel centering to meet or exceed USP and/or ASTM mechanical calibration specifications.
