Speedwave® four Microwave Digestion Systems

Berghof 'speedwave® four' microwave digestion system - uncomplicated and straight forward digestions.

Speedwave makes laboratory work easier and safer. Very easy handling thanks to the top loading concept. The entire, heavy rotor no longer needs to be lifted and placed in the microwave oven. It remains in the oven chamber and the vessels are simply inserted individually and removed again after digestion. The heated vessels can be removed immediately after the digestion. The sample throughput rate is significantly raised because the cooling down phase is omitted. All of the digestion vessels consist of only a few individual parts and are correspondingly fast and easy to close or open. It is handled manually without any special tools. Optimal safety because of contactless temperature and pressure measurement.

The contactless sensor technology simplifies working with the system and reduces operating costs. It is no longer necessary to perform measurements in a reference vessel. There is no need for sensor connections. Dip tubes are no longer needed to be mounted, sealed and cleaned. The speedwave® DIRC thermometer for contactless measurements measures the temperature of every single sample solution directly. There is no time delay owing to heat up the vessel walls or sensors. The equally contact-free, optical pressure control captures all of the internal pressures of each vessel. It is not necessary to take measurements in a reference vessel. The microwave output is controlled via the specified temperature profile. This combination of temperature and pressure control enables ideal process control and ensures optimal safety.

Low operating costs since Berghof uses only pressure vessels made from TFMTM-PTFE. The vessel and lid are corrosion and pressure-resistant and produced entirely from this material. A pressure jacket and/or lid made from a different plastic material which is partly microwave-transparent and not resistant to acid (e.g. PEEK) is not necessary. The material used guarantees the vessels a service life of at least 3-5 years. Hence the vessels are no longer regarded as consumables and are therefore logically included in the instruments warranty. The 'speedwave® four' significantly reduces the operating costs for microwave pressure digestion.
