Questron Technologies

• 208-240VAC, 50/ 60Hz, 15A, Fully CSA, and UL compliant oven
• Dual Magnetrons for high power digestions
• Wireless control by Android based tablet computer QL-101-501
• Powerful and friendly user interface with touch screen, 7” display
• Preloaded EPA 3015, 3051 3052 and other digestion methods
• Unlimited digestion recipes can be developed and stored
• Software allows users to edit, save and run methods. Printouts are also
• Ports to transfer methods or update software with data storage of about 6 GB
• Temperature and pressure monitoring and real-time graphical display of
digestion parameters of each vessel
• IR temperature sensing for remote/ non-invasive temperature measurement
of all vessels
• Facility of additional in-situ pressure sensing vessel and/ or temperature sensing
vessel. This is not necessary as every vessel is monitored with a non-contact
• Capable of identifying vessel in case of over pressure
• Microwave power available in small increments
• Rotating antenna and 360° carousel rotation ensuring uniform microwave heating
• Ease of loading carousel vessel by vessel within the system
• Real-time graphical display for digestion parameters
• High efficiency 150 CFM, 2-speed blower built-in for fume exhaust and
post-digestion vessel cooling inside the oven
• Corrosion resistant PTFE coated reinforced stainless-steel cavity and acid resistant
polymer shell for long life
• Cavity volume 56 litres 40 X 40 X 36 (h x d x w)
• System cavity has a capability of sensing device to automatically turn off the
system if a vessel event occurs
• Spring-loaded door that automatically relieves pressure in the case of a vessel
event to provide additional safety
• Up to 1800 Watts power output
• 2450 MHz magnetron frequency
• Magnetron power cut-off in case of over limit pressure release
• Full absorption of reflected microwave energy at 100% power
• Auto Shut off function for system shut down if full power is applied over a specified
time to prevent runaway reaction
• Compatible with Questron 18-eVHP or 40-LVHT vessel sets
• Option of QBlock pre- and post-digestion treatment of samples in microwave
digestion vessel liner itself to minimise contamination, concentrate samples, boric
acid treatment for excess HF acid or evaporate excess acids
• Requires 60-65psi air at 1-2 litres per minute with ¼” pneumatic connection for
plastic pipe
