Description

The UltraCLAVE performs beyond the current limitations of traditional microwave sample preparation. Chemists can digest large sample masses, large batches of mixed sample types, and even the toughest sample matrices requiring sustained high temperatures.

Cross-contamination does not occur and extremely high throughput can be achieved.
Finally, reduced acid usage, consumables, and need for labor provide long-term cost savings.

The UltraCLAVE is based on high pressure autoclave design: at its heart a single large reaction sample-containing chamber is pre-pressurized with inert gas and then heated by microwaves.
The pressurized chamber serves simultaneously as the microwave cavity and the reaction vessel.
The patented Milestone UltraCLAVE achieves extraordinary performance capabilities by combining direct microwave heating in a high pressure reactor. It offers all the advantages familiar to microwave users: speed, quality of results, reproducibility, and no pollution of the laboratory or environment, while overcoming the restrictions of traditional microwave digestion systems.

TECHNOLOGY

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.

AUTOMATIC OPERATIONS

Step 1

Sample rack is lowered automatically into microwave chamber

Step 2

Chamber clamp is secured by the operator

Step 3

Chamber is pre-pressurized with inert gas to prevent sample boiling

Step 4

Microwave energy is applied.
All samples under same temperature and pressure

Step 5

Very fast cooling step due to water cooling of chamber

Step 6

Clamp is released and sample rack automatically rises from chamber

Wide choice of digestion vessels

Several standard racks are designed to hold 6 to 77 individual sample containers made of glass, quartz, or TFM. They can be much simpler in design than in conventional microwave vessel assemblies.

From sequential process to a parallel one

By eliminating the traditional control strategy, chemists are no longer constrained to process batches of identical samples using identical sample chemistries.

Even certified reference materials can be processed along with unknown sample for method validation.

This transformation of a sequential process into a parallel one may prove to be the greatest source of increased efficiency in many laboratories.
