Berghof presents a system for microwave digestion: the Speedwave Four. The handling of the entire system is very easy thanks to a contact-free sensor system (the sensors do not need to be connected), the top-loading design and the vessels comprising only few individual parts. The vessels can be locked and opened simply by hand without any special tools.
Furthermore, the vessel and lid are completely made of pressure-proof TFM-PTFE. A pressure shell or lid made from another material that is only partially microwave-transparent and non acid-resistant plastic materials are not needed. This is why a service life of at least three to five years can be achieved. The vessels are no longer regarded as consumables and are therefore logically included in the device warranty. The operating costs of the digestion system are significantly reduced.
