Derivatisation

Chromatography and spectroscopy
Derivatisation reagents can be applied either manually using a spray bottle with a rubber bulb, or using an automatic sprayer, which allows for uniform application and reduces the amount of reagent required. 

Advantages

  • The spray chamber acts as a protective device for spraying corrosive solutions onto thin-layer chromatography (TLC) plates.
  • If a fume cupboard is not available, the reagent mist can be channelled to an extraction port or ventilation outlet using a standard NW100 suction hose (optional), whilst excess reagent is collected in a separate tray.

Features

  • The built-in fan has a quiet motor (400 m³/h).
  • The sprayer housing is made of acid-resistant PVC.
  • It is suitable for plates measuring up to 200 x 200 mm.

TLC Plate Heater

The Thermoplate S+ system is an electronically controlled system for heating plates used to detect reactions in thin-layer chromatography, designed for precise heating and drying in the laboratory. 

Advantages

  • The set temperature is maintained constantly to within 2°C.
  • The temperature is displayed on a colour touchscreen, the colour of which changes from green or blue to red as the temperature rises. This means the user can visually see whether it is safe to touch the plate.
  • An audible signal alerts the user as soon as the set time or temperature is reached.
  • The heating surface is made of highly conductive aluminium, which, combined with the extremely large surface area of the heating element, ensures even temperature distribution.

Features

  • The operating range is from 25 to 200°C.
  • In addition, up to 9 programmes can be saved.

ChromaJet DS20 automated derivatiser

The ChromaJet DS20 is a microprocessor-controlled sprayer for applying derivatisation reagents to thin-layer chromatography (TLC/HPTLC) plates.  The advantages over manual spraying include a significantly reduced amount of reagent used, a very uniform spray pattern and the avoidance of aerosol formation.  Reagent application is carried out with the highest precision and is reproducible at any time.  This device, which enables TLC operations to be carried out in accordance with GLP guidelines, protects the user’s health from any chemical risks (inhalation and splashes). The ChromaJet DS20 can operate stand-alone or connected to a PC. Using specialised software, you can create, save and load various spraying methods.

Advantages

  • Virtually no aerosol formation
  • Significantly reduces reagent consumption
  • Suitable for all common reagents
  • Compliance with GMP/GLP

Features

  • Spraying onto precise areas pre-defined by the operator
  • Automatic rinsing system
