Full description

The CAMAG Automatic Developing Chamber 2 (ADC 2) is a device for reproducible plate development. It performs the development step fully automatically, and independent of environmental effects. The activity and pre-conditioning of the layer, chamber saturation, developing distance and final drying can be preset and automatically monitored by the ADC 2. Two modes of operation are possible: stand-alone with input of parameters via keypad, or remote operation from visionCATS with process monitoring, documentation of operating parameters, and reporting.

With visionCATS the ADC 2 can be IQ/OQ qualified and used in a cGMP environment. Operated with the mentioned software, the ADC 2 supports compliance with 21 CFR Part 11.

Key features
• Fully automatic development of 20 x 10 cm HPTLC plates
• A conventional 20 x 10 cm Twin Trough Chamber is used for development. This way, chromatographic conditions of already existing analytical procedures can be retained, but environmental and operational effects are excluded.
• Operation in stand-alone mode or software-controlled
• The user is freed of all process monitoring responsibilities, operation is fully traceable.
• The option “Humidity Control” allows reproducible chromatography at defined activity of the layer. This feature is essential in method development when the influence of relative humidity shall be investigated.
