The ultraCLAVE shares Single Reaction Chamber (SRC) technology with the ultraWAVE (link), offering all the same great benefits, speed, quality of results, reproducibility, and
no pollution of the laboratory or environment, while overcoming the restrictions of traditional microwave digestion systems.
At its heart a larger reaction chamber can accommodate up to 40 samples in 20 mL disposable glass vials and it is pre-pressurized with inert gas and then heated by microwaves. The pressurized chamber serves simultaneously as the microwave cavity and the reaction vessel.
Chemists can digest large sample masses, large batches of mixed sample types, and even the toughest sample matrices requiring sustained high temperatures. Cross-contamination is non-existent and extremely high throughput can be achieved. Finally, reduced acid usage, consumables, and need for labor provide long-term cost savings.
Automatic operations with the unique ultraCLAVE technology
The patented Milestone ultraCLAVE achieves extraordinary
performance capabilities by combining direct microwave heating in a high pressure reactor, which acts simultaneously as microwave cavity and vessel. Microwave energy is introduced into the reactor through a unique microwave port. This focused-multimode cavity design ensures maximum sample heating efficiency. Heat generated in the reactor is removed by a re-circulating cooling system, and the stainless steel vessel remains at approximately room temperature throughout the entire heating cycle. The ultraCLAVE is designed for simplicity of use. Loading a rack of samples into the chamber is the only manual operation required. The reaction chamber is sealed, pressurized, heated, cooled, vented, and opened all under computer control. The system dramatically reduces the labor compared to conventional microwave systems.
Several standard racks are designed to hold 6 to 77 individual sample containers made of glass, quartz, or TFM.
Moreover, with the ultraCLAVE it is possible to process a single, very large sample in a TFM liner fitted to the entire reaction chamber. The individual sample vessels are much simpler in design than in conventional microwave vessel assemblies, ensuring long-term cost savings.
Many dissimilar samples and chemistries can be combined in a single run in the ultraCLAVE.
Chemists can digest large batches of mixed sample types and even certified reference materials can be processed along with unknown samples for method validation.
