Microwave Reaction System for Sample Preparation: Multiwave PRO
The Multiwave PRO microwave reaction system delivers the high-quality solutions you need to obtain excellent trace analysis results, even with complicated, demanding samples. Multiwave PRO masters high temperatures and provides comprehensive safety features. Its wide range of accessories allows digestion, leaching, oxygen combustion, solvent extraction, drying, evaporation, and UV digestion with one single system.
  1. Features
  2. Specification
 True power
-       Multiwave PRO brings you the strongest microwave power on the market. To sustain an output level of 1500 W (IEC 705) over years, Multiwave PRO is equipped with two reliable magnetrons of 850 W each.
 
-       Unpulsed microwave power over the whole range ensures precise control of critical reactions.
 
fast and quiet cooling: The integrated forced-air cooling system with air gap design cools the vessels within minutes after heating digestion.
 
Get in touch: Multiwave PRO has a large color touchscreen for convenient operation which is easy to read from a distance. The on-board PC provides a multilingual and intuitive software solution.
 
Convenient tool-free handling
Opening and sealing Multiwave PRO’s rotors, vessels and sensors is quick and simple - just use your hands. This tool-free handling is unique to Anton Paar and simplifies this frequently repeated work step.
 
Satisfying results - with dual reaction control
Multiwave PRO has a dual solution for reaction control: an immersing temperature probe with integrated pressure sensor is positioned in one reference vessel and infrared sensors are located underneath the rotor to simultaneously measure the temperature and pressure of each vessel. For convenient handling, the sensors transfer values to the Multiwave PRO wirelessly, so you do not need to connect cables before loading the rotor.
 
 
 
By measuring the pressure in all vessels every 20 milliseconds
The result: an extremely quick and simultaneous pressure measurement in Rotor 8N makes Multiwave PRO considerably safer and more efficient. This allows you to apply the highest possible
temperatures for acid digestion. Critical situations emerging from, for example, spontaneous reactions are intercepted due to the high frequency of pressure measurement. Multiwave PRO immediately reduces microwave power and the unwanted reaction is stopped before it leads to pressure release.
 
 
Acid digestion
Multiwave PRO handles complete acid digestion of samples in a fraction of the time required by conventional techniques. Routinely providing temperatures up to 300 °C, Multiwave PRO successfully digests even the most demanding materials.
 
Leaching: As standardized by EPA and ASTM
Multiwave PRO is fully compliant with EPA and ASTM standard leaching, digestion and extraction methods. Sensors monitor each vessel for continuous control and documentation of reaction parameters.
 

 

Solvent extraction: Rapid
Applying high pressure allows extractions at temperatures far above the solvent’s normal boiling point. Multiwave PRO drastically reduces the reaction times compared to conventional methods.
 

 

Oxygen combustion: Unique and brilliant
A unique accessory allows you to burn pelletized samples in pure oxygen above 1000 °C. Analytes are absorbed in small amounts of liquid, making this procedure quick, clean and safe.
 

 

UV digestion: Unrivaled
A unique accessory produces intense UV radiation inside liquid samples. Radicals destroy organic matter within minutes, almost without acid.
 
Additional methods: Drying, acid evaporation and protein hydrolysis
Multiwave PRO supports unique additional methods around acid digestion, all in one system. This includes drying samples before digestion and evaporation of acids after digestion. It also provides acid hydrolysis of proteins for structural analysis in biotechnology.
