The technology that revolutionized microwave sample preparation

Featuring patented SRC technology ultraCLAVE enables processing of mixed matrices in the same run with different chemistries. ultraCLAVE uses vials and racks instead of vessels and rotors to remove the handling step in sample preparation setting new standards in microwave digestion.
Eliminating this essential step ultraCLAVE completely changes the rules in microwave sample preparation enhancing overall efficiency in elemental analysis. Representing new generation of microwave reaction vessel with high pressure reactor ultraCLAVE is capable of running as many as 77 samples simultaneously at high temperature up to 300 °C and pressure up to 200 bar, thus enhancing lab efficiency.
  •  Market-leading innovation
  •  Fully automated
  •  Enhanced performance
  •  Unsurpassed throughput
  •  Great return on investment

A step forward in sample preparation automation

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.

The operating sequence with SRC technology

Sample preparation is the most labor-intensive step in elemental analysis, as it requires assembling, closing, opening and disassembling of the vessels. These operations involve a lot of handling, which is directly affected by the number of vessels used. The ultraCLAVE with SRC technology, uses vials and racks instead of rotors and vessels, completely removing laborious handling. SRC technology is based on a stainless-steel reactor with a volume in excess of 4 L, which act as both a microwave cavity and digestion vessel. A 3.5 L PTFE vessel with a base load is introduced into the stainless-steel reactor. The operator places the samples and acids into vials with loose-fitting caps, places the rack in the ultraCLAVE and the digestion process begins (Step 1). By pressing “START” on the dedicated large screen terminal, the system automatically closes the stainless-steel vessel and clamps, loads the nitrogen pressure and runs the pre-selected microwave program (Step 2). After completion the vials are cooled using a powerful external chiller, pressure is safely released, and the main reactor opens, delivering the digested solutions ready for dilution and analysis (Step 3).


Gain efficiency without compromising performance


The combination of stainless-steel reactor with microwave technology results in a digestion system with superb performance and abilities. The temperature range up to 300 °C allows for the digestion of virtually any sample, while the maximum pressure of up to 200 bar allows for digesting very large sample amounts. Highly reactive samples such as large amounts of food, pharmaceuticals, polymers and petrochemicals can be completely digested. Furthermore, the platform's flexibility found a natural fit in other analytical testing labs such as environmental, clinical and biological. The ultraCLAVE allows for the simultaneous digestion of completely different matrices with different chemistries, as the set conditions in the stainless-steel cavity are applied to all vials, ensuring complete digestion of all samples in the reaction chamber.
Greater productivity & ROI
SRC technology offers high throughput without compromising productivity. The ultraCLAVE greatly reduces handling and operator time, eliminates the need to batch the samples and to clean of vials, resulting in a more productive approach to digestion across multiple industries. Most samples will be digested using a single program, eliminating method development and simplifying the digestion procedure. The ultraCLAVE is an efficient tool for mixed or similar samples. Lab throughput is greatly enhanced, with a digestion cycle taking about 60 minutes for 40 or 77 samples. Lab efficiency is improved by removing the need to batch samples, speeding up the digestion cycle and using inexpensive consumables. The ultraCLAVE offers superior productivity, ease of use and performance far surpassing any conventional digestion system.



Digestion vials

SRC technology completely changes the rules of sample preparation. Instead of using a traditional digestion rotor, a rack and vials with loose-fitting caps are used, which greatly simplifies daily operation and reduces running costs. The ultraCLAVE racks are available in several configurations to accommodate varying sample throughput needs as well as large sample masses.
Several racks are available and the selection of vials includes high-purity PTFE, quartz and disposable glass.
The use of disposable glass vials eliminates the tedious cleaning step, improving lab workflow. Rack handling is as simple as hanging it in the system. Moreover, SRC technology allows for the use of a single method regardless of the sample type and amount, making it possible to digest different matrices together in the same run.
