The Ultimate Solution for all Your Sample Digestion Needs

1. The Ultimate Solution for all Your Sample Digestion Needs Questron Technologies Corp. Chemistry – with Precision

2. Rugged Design with Enhanced Safety Features • • Ideal for digestion, extraction, evaporation and synthesis Built in temperature and pressure monitoring of each digestion vessel User independent safety features guarantee safe digestions Controled release of over pressure to avoid cross- contamination Rotating antenna and 360° carousel rotation ensuring uniform microwave distribution Corrosion proof PTFE-coated reinforced cavity for corrosion ressistance Microwave power output in small increments for finer temperature control 150 CFM exhaust for fumes removal and vessels cooling Spring loaded door latches for enhanced safety • • • • • • • eVHP Vessels set Vessel Station LVHP Vessel • • • • • • • • Temperature sensing with accuracy (±0.1°C sensitivity) Ease of loading carousel vessel by vessel within the system Very convenient to release pressure at the end of digestion Compact Vessel Handling Station builds vessel every time correctly Capable of identifying vessel in case of over pressure Choice of sensor vessels for in-situ temperature and pressure measurement Automatically protects against unusual heating of vessels Optimally designed carousel ensures uniform heating of all samples • Vessel for high throughput & moderate temperature requirements Ideal solution for labs running large number of samples in every batch Standard vessels are individually pressure controlled and each equipped with rupture disk-based pressure venting system • •

3. Full-colour Touchscreen Interface • User friendly control panel, operated through full color bright LCD touchscreen Easy navigation for method creation and storage Audible alarm and visual alerts during digestion runs Preloaded with EPA and other standard methods Archives data from all method runs for future reference Data export capability for tracking, tracing, and documentation • • • • • System Status Real time graphical & digital display Temp. & Power Digestion Progress Recipe Details Easy to create and store unlimited number of multi-step digestion recipes OPGuard™ All vessels are individually pressure controlled using our unique resealing over-pressure guard (OPGuard™) vessel protection system. This system rreleases pressure vertically in controlled manner to achieve safe limit, helping quick removal of fumes and avoiding condensation on cavity and vessels. If release is a minor, drop in temperature are minor and digestion method can be continued. Unique QSens technology ensures complete safety by cutting off magnetron power, activating audible alarm and displaying visual warning.
