Discover SP-D Pressurized Microwave Digestion

The Discover SP-D is the most revolutionary microwave digestion system designed since CEM introduced the first system 25 years ago. It is more than the latest technology for microwave digestion: it is a new concept in sample preparation. Discover SP-D is a sequential, pressurized microwave digestion system that processes samples in 10 minutes or less, including cool down! There are no complicated, heavy vessels, no chillers required, and no need to batch samples. For Discover SP-D, simplicity is an integral part of the system, with every aspect of the instrument designed to make it virtually effortless.
