Innovative & Flexible Sample Prep Solutions

Microwave Assisted Sample Digestion

With Safety, Economy & High Throughput

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 ensuring safe digestions

• Controlled 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 resistance

• Two-900 Watt magnetrons provide continuously variable, non-pulsed, evenly distributed power in small increments for precise temperature control of every vessel.

• Two-speed, 150 CFM exhaust for fume removal and vessel cooling

• Spring-loaded door latches for enhanced safety

QWave 1000: Single Magnetron system Closed & Open Vessel Digestions Open Vessel configuration comes with External exhaust blower to take care of excessive acid fumes generated during operation

QWave 2000 Dual Magnetron High Power System for Closed Vessel Sample Digestions

Control Panel Interface

• User-friendly control panel, operated through touchscreen

• Easy navigation for method creation and storage

• Audible alarm and visual alerts during digestion runs

• Preloaded with Methods library of EPA and other standard methods

• Capable of identifying a vessel in case of over pressure release

• Data export and printing capability for tracking, tracing, and documentation

Temp. & Power

All vessels are individually pressure controlled using our unique resealing over-pressure guard (OPGuard vessel protection system. This system releases pressure vertically in a controlled manner to achieve safe pressure conditions.

Released fumes are removed quickly to avoid condensation on cavity and vessels.

If release is minor and drop in temperature is minimal, the digestion method can be continued. In an instance where pressure release is major, complete safety is achieved by automatically cutting off magnetron power, activating audible alarm, and displaying visual warnings

Vessel Workup Stations

Process of assembling and dissembling a digestion vessel using the eVHP Workup Station

• Option of QBlock digestion system for pre- and post-digestion treatment of samples in digestion vessel liners

• Prevent contamination from use of multiple vials

• Partly digest organic-rich samples in QBlock at low temperatures to increase sample handling capacity of microwave digestion vessels

• Concentrate samples before microwave digestion treatment

• Give boric acid treatment for excess HF acid

• Evaporate excess or unwanted acids at the end of digestion
