U2 ultra-microwave digestion ![U2 ultra-microwave digestion, Preekem](/suppliers/preekem/u2-hero.webp) [Preekem](/leverandoerer/preekem/) # U2 ultra-microwave digestion Pressurised ultra-microwave digestion up to 300 °C and 200 bar, for difficult-to-digest matrices in petrochemicals, environmental and metallurgy applications. Up to 82 vessels per batch. - Microwave digestion - [Environmental labs](/segmenter/miljoelaboratorier/) - [Refining and petrochemicals](/segmenter/petrokemi/) [Request a quote → ](/kontakt/?intent=quote&supplier=preekem&product=preekem-u2&utm_source=product&utm_medium=internal&utm_campaign=quote_request) [Contact sales](/kontakt/?intent=consult&supplier=preekem&product=preekem-u2) ## Applications - Refractory samples beyond the reach of standard TFM vessels, e.g. petroleum coke, catalysts and slags - High throughput of routine samples in environmental labs (soil, sediment, sludge, ash) - Petrochemical matrices: oils, additives, polymers - Metallurgical samples for total analysis of trace elements - Pulp & paper: additives and process chemicals ## Specifications Microwave power 1500 W Cavity volume 2.5 L Max temperature 300 °C Max pressure 200 bar Rack positions 10, 20, 30, 50 or 82 vessels (can be customised) Inert gas Nitrogen or argon, pressurised reaction chamber Vessel material Glass, quartz, PTFE Cooling Circulating cooling water Safety Multi-level protection for pressure, temperature and gas leaks ## Description U2 is Preekem's latest generation of microwave digestion in which the reaction chamber is pre-pressurised with inert gas. The higher pressure and temperature capacity (up to 200 bar and 300 °C) means that even the most difficult-to-digest matrices can be completely decomposed without needing special vessels for each sample type. With rack positions for up to 82 vessels per batch and support for glass, quartz, and PTFE vessels, the same instrument handles both routine workflows in environmental labs and challenging petrochemical or metallurgical samples. Dual heating and a common method for multiple matrices simplify method validation and documentation. Through lower acid consumption (up to 50% per sample) and the possibility of using disposable glass tubes, operating costs are significantly reduced compared to conventional systems. ## Documents & datasheets - [Product page U2 ultra-microwave (Preekem) Opens in new tab ↗ ](https://www.preekem.com/en/product/microwave-digester/u2) ## Service & support Labsense provides service, periodic calibration and spare parts supply for Preekem instruments from our own technicians centrally located for the Nordic region.
