NOVA-10 Rotor

High Temperature, Long Duration

Innovative rotor allows complete digestions of traditionally difficult samples

Milestone is proud to offer the first high-temperature rotor designed to withstand the most extreme of working conditions.

The main limiting factor in microwave digestion applications has always been the reaction vessel technology. Historically, certain difficult sample types (such as ceramics, refractory metals, metal oxides, carbides, and geologicals) could not be digested, because the existing technology could not withstand the necessary high temperatures for extended periods.

Milestone's Nova-10 rotor opens the door to previously unavailable applications in the microwave. It combines a breakthrough twin shielding technology (ceramic and high-performance polymer shields) with an architecture optimized for free air flow and efficient cooling. This design, in conjunction with Milestone's EasyControl software, provides reliable performance at sustained high temperatures of 280°C for up to 2 hours.

NOVA-10 Features & Benefits Most Difficult Samples Complete digestions of extremely difficult samples, e.g., metal carbides, metal oxides, metal nitrides, precious metal alloys, zircons. Longest Time at Highest Temperatures Innovative twin shielding technology for improved insulation/cooling. Hold extremely high temperatures for several hours—e.g. 2–3 hours at 270–280°C. Improved Durability Designed for optimized air flow around open architecture. Ceramic shielding enhances vessel strength. New high-performance polymeric materials resist thermal softening & deformation, for increased lifetime of PTFE vessels and covers. Increased Sample Throughput Up to 10 samples can be processed simultaneously. Highly effective cooling speeds up sample turn around and reduces stress on the rotor. Compatible with All Milestone Ethos Labstations The Nova-10 can be supplied as part of a standalone system, or can be used in any existing Ethos labstation to expand that laboratory's range of capabilities.

Twin Shielding Technology

The Nova vessels feature two layers of shielding (one ceramic, the other a high-performance polymer compound) and an architecture optimized for free air flow. This design provides efficient, optimized cooling during the microwave process, and is a key to the rotor's unequalled performance.

This technology enables the chemist to digest previously impossible samples. For example, wet digestion of refractory and geochemical samples usually carried out only by alkaline fusion, is now possible in the microwave.
