Automated spraying device for reagent transfer onto TLC/HPTLC plates

The CAMAG® Derivatizer is an automated spraying device for reagent transfer onto TLC/HPTLC plates setting a new standard of reproducibility and convenience in reagent transfer onto TLC/HPTLC plates by employing a unique “micro droplet” spraying technology (patent pending). This video explains more about the technology...

 

 

The device is suitable for all common reagents. In addition to the unsurpassed homogeneous reagent distribution, the Derivatizer offers other advantages as compared to manual spraying and immersion.

  • Environmentally friendly and safe handling through a closed system
  • Reproducible and user-independent results
  • Low reagent consumption (2-4 mL) through efficient operation
  • Intuitive handling and easy cleaning.

How it works

At the push of a button, the transparent hood automatically lifts so that the user can remove the plate tray and place the TLC/HPTLC plate on it. After the tray is inserted into its original operating position, the hood is lowered and completely sealed to prevent aerosols spraying reagent from leaking to the outside. The user fills the required reagent volume into the appropriate nozzle, selects the optimum spraying level and starts the reagent transfer. To meet the divergent physicochemical properties of the reagents (e.g., viscosity), four different colour-coded nozzles are available, and the user can select from six spraying modes. The nozzle generates an extremely fine reagent aerosol, which evenly distributes in the chamber and gradually settles down on the TLC/HPTLC plate. Any residue remaining in the gas phase is automatically aspirated by the integrated pump and collected in the wash bottle behind the instrument. After the reagent transfer has been completed, the hood lifts at the push of a button and the TLC/HPTLC plate can be removed for further processing.
