The CAMAG Derivatizer is an automated spraying device which sets a new standard of reproducibility in the reagent transfer onto TLC plates by employing a unique "micro droplet" spraying technology (patent pending). It ensures homogeneous and reproducible application of the most common reagents. To meet the diverging physicochemical properties of the different reagents, e.g. acidity or viscosity, four different color-coded spray nozzles are employed, and the user can select from six spraying levels.


In addition to the significantly increased homogeneous reagent distribution, the Derivatizer offers other advantages compared to manual spraying:

  • Environmentally friendly and safe handling through a closed system

  • Intuitive handling and easy cleaning

  • Low reagent consumption through efficient operation (4 mL for 20 x 20 cm plates and 2 mL for 20 x 10 cm plates)

  • Reproducible and user-independent results

Chromatogram Immersion Device

For proper execution of the dipping technique, the chromatogram plate must be immersed and withdrawn at a controlled uniform speed; otherwise tide marks may be left which interfere with densitometric evaluation. By maintaining a well defined vertical speed and immersion time, derivatization conditions can be standardized. The immersion device can also be used for the pre-washing of plates.


Key features

  • Uniform vertical speed, freely selectable between 30 mm/s and 50 mm/s

  • Immersion time selectable between 1 and 8 seconds and indefinitely (upward movement at another touch of the button)

  • The device can be set to accommodate 10 cm and 20 cm plate height.

  • Battery operated

TLC / HPTLC Sprayer & Glass Reagent Spray



The function is electro-pneumatic. Reagents are atomized into a fine aerosol spray with particles in the range of 0.3 to 10 μm. This ensures a homogeneous distribution over the layer at low reagent consumption. The TLC Sprayer consists of the charger and a pump unit with two kinds of spray heads, type A for spray solutions of normal viscosity (organic solvents), and type B for liquids of higher viscosity (e.g. sulphuric acid containing reagents).


Glass Reagent Spray

This all glass reagent sprayer is a low cost alternative to the TLC/HPTLC Sprayer. It comes with a rubber pump but may also be operated from a compressed air or nitrogen supply. The Erlenmeyer flask may be closed with a standard glass stopper.

TLC Plate Heater


The TLC Plate Heater is designed for heating a TLC/HPTLC plate to a selected temperature after a staining reagent has been applied. The Plate Heater has a CERAN® heating surface which is resistant to all common reagents and is easily cleaned.


The 20x20 cm heating surface has a grid to facilitate correct positioning of the TLC plate. Programmed and actual temperatures are digitally displayed. The temperature is selectable between 25 and 200 °C. The plate heater is protected from overheating.

TLC Spray Cabinet


The TLC Spray Cabinet is designed for the complete removal of excessive spray mist while spraying a TLC plate with reagent. There is no deflection of the spray jet before it reaches the plate, an effect often encountered in a normal laboratory fume hood. Particles rebounding from the plate are completely removed.


The Spray Cabinet is also useful for drying plates after development, with or without the assistance of a hair dryer. The cabinet is made of PVC The blower, a radial fan driven by a motor outside of the fume duct, produces airflow of 130 cubic feet (3.7 cubic meters) per minute. The bottom of the spray cabinet has a built in tray, which is removable for easy cleaning.
