Features

Unique vessel cooling system

Cooling time is no longer a limiting factor! MULTIWAV’s built-in forced-air cooling system prevents overheating and cools vessels in minutes after the end of a decomposition. Special air gap design and the use of quartz and ceramics provide efficient hegt transfer.

•            Drastically reduced cycle time

•            No external cooling required

•            No handling of hot pressure vessels

IR temperature Sensor

Temperature curves of each sample are displayed by the integrated Com­puter. An infrared sensor measures the temperature at the bottom of each vessel through ports in the rotor base.

•            Temperature controlled and docu­mented process

•            Protection against overheating

•            Remote sensing - no installation, no contamination

Double safety door

Maximum safety is a major benefit of the MULTIWAVE system. Users are

efficiently protected in case   of spontaneous reactions. The extensive safety measures are completed by a shield an the oven door, which remains locked when the inner door opens for safe and controlled release of overpressure.

•            Multiple door interlocks

•            Easy one-latch operation

PTFE-coated cavity

Durable, industrial-quality components make the MULTIWAVE suitable for harsh laboratory conditions. Its stain­less steel cavity is completely pro­tected by a multi-layer PTFE coating.

•            Maximum corrosion resistance

•            Easy cleaning and maintenance

Unpulsed microwave power

Precise regu!ation of energy is particu­larly important for sensitive reaction control. MULTIWAVE delivers unpulsed microwave power over its full 1000 W Tange, controlled by reaction Pressure or temperature.

•            Fast and efficient heating

•            Increased service life of magnetron

Built-in industrial-type PC

On-line documentation and control of process parameters is available at the push of a button. MULTIWAVE has its own built-in computer and provides

you with intelligent and comfortable software solutions. lt contains compre­hensive sample and methods libraries including standardized EPA-proce­dures (3015, 3051, 3052). Use them as they are or customize them to create your own methods.

•            Built-in "digestion experience"

•            Software safeguards

•            Bright graphic display

Output to printer or PC

Serial RS232 and parallel Printer interface is standard for every MULTIWAVE.system. For GLP-compliant documen­tation simply connect a printer or transfer data to an external host PC.

Magnetic stirrer (option)

Reaction rates and recoveries can be further enhanced with a magnetic stirrer. MULTIWAVE provides this option to intensify contact of sample and reagents in vessels H F50 and MF100.

Gas/vacuum connections (option)

For inert gas purging or evaporation applications optional ports are available for the connection of scrubbers, etc

High Performance Reaction Vessel System

Reaction vessel performance is the basis for decomposition quality. The Anton Paar MULTIWAVE system offers a well balanced choice of vessels and rotors with exceptional modularity and inter­changeability. This flexibility allows you to select optimized systems for a wide variety of organic and inorganic matrices. The use of advanced materials provides the outstanding vessel specifications.

All MULTIWAVE vessels are designed for safe, convenient handling. Unique, patented features like self-sealing lip-type seals, air cooling and remote sensing systems reduce working steps and errors and increase the productivity of your analytical lab.

- Superior digestion quality eliminates chemical interference during the analysis

- Hermetic seal avoids losses or contaminations

- Short cool-down timen provide high sample throughput

- Compound designs Show unmatched dimensional stability and Service life

- No pressure derating at max. temperature!

12 position Rotor 12LF100

For samples that decompose at moderate temperature and pressure the Rotor 12LF100 is the maximum productivity workhorse. 100 mL reaction vessels with high over­pressure tolerante make decompo­sitions safe and efficient. A reference pressure sensor vessel is used to control the process. Up to nix vessels can be temperature controlled. The integrated air cooling system reduces sample turn-around time and material stress.

•            Installation-free sensor technology

•            Easy handling of seals and vessels

•            High safety level

6 position Rotor system

Ultimate flexibility, performance and reaction control is characteristic for the 6-position rotor system:

•            Continuous temperature and pressure control in every vessel

•            Four different typen of heavy duty vessels fit into the saure rotor

•            Multiple safety devices

Work with MULTIWAVE to convince yourself how easy it is to use! Hand­tightening of vessels and rotor make setup quick and simple. No sensor connections or other tedious Installa­tion steps are required. Maximum compatibility of components allows you to change simply from one vessel type to another with automatic cut-off pressure matching.

Most advanced pressure sensor technology

Decomposition is now safe and easy, even for inhomo­geneous samples or partially loaded rotors, with MULTIWAVE's unique pressure sensing system. lt simulta­neously measures the pressure in all vessels of the 6-position rotor, always using the highest level in any of the vessels for accurate reaction control. Designed as a closed load cell, the sensor neuer contacts the sample. The remote sensing system doesn't require any honen, water fillings, not even electrical connections. Just innert the rotor into the cavity and the pressure sensor is ready to work.

•            Simultaneous pressure control of all vessels

•            No Installation, no tools required

•            No sample contamination
