Faster & Consistent

Microwaves coupled with SiC are known to produce high temperatures at a much faster rate compared to old electrical heating furnaces. QAsh has a software controlled air inlet inside the ashing chamber which fuels the ashing process. The introduction of air at the source pushes ashing by-products out. An alumina fibre ashing chamber helps retain heat. This provides an efficient ashing process. Vertically placed SiC plates, in conjunction with ceramic insulation, create uniform temperatures across the ashing chamber. The R type thermocouple is encapsulated in a chemical resistant material. It measures temperatures accurately over the working range of 25°C to 1,200°C.

 

Cleaner & Cooler

Software controlled compressed air or nitrogen gas are introduced into the chamber to draw out fumes and soot. The built-in fan and external blower purge hot gases for safe disposal and results in a cleaner system interior and a cooler exterior. This assists in maintaining a comfortable working environment. The exhaust port has a filter trap to prevent particulate matter and other ashing by-products from entering the exhaust fan thus increasing the life of the exhaust fan..

User-Friendly Software Control

  • Easy-to-build ashing recipe with multiple heating steps and air control settings.
  • Calculates sample weight and % ash content.
  • Displays ashing process time and thermal changes graphically.
  • Capable of connecting to external Weighing balance for direct weight transfer.
  • Manual panel provide control over various functionality.
  • Ashing data is collected and stored for archiving or future viewing in graphical or tabular formats.
