The easiest, safest and most intelligent microwave digestion system on the market.


Better digestions for better analyses
Now with iWave & iLink

Acid digestion is vital for the preparation of samples for elemental analysis by ICP, ICP-MS or AA spectroscopy. Traditional acid digestion techniques using a hot plate are time consuming and often provide incomplete digestion. In addition, due to the acid fumes released from open vessels, this technique causes unnecessary corrosion and hazardous working environments.

With CEM’s innovative closed vessel design and acid resistant microwave digestion systems, high temperatures and pressures can be achieved, resulting in the rapid digestion of all sample types.

Sample preparation time is reduced from hours to minutes, using less acid, retaining all volatiles and providing a much safer laboratory environment. Whether your work flow requires batch digestion or sequential/ad-hoc tests, CEM have the solution with instrumentation to digest any type of organic and inorganic samples.

One-Touch Technology

One Touch is like having a CEM chemist at your side. One Touch Technology features the industries only vessel recognition and counter sensors. This information is fed to the onboard computer which then selects the exact digestion conditions required for the sample load and vessel type. One Touch also has more than 100 pre-programmed methods, including all USEPA methods, as well as on board tutorial videos. With One Touch you simply choose your method and the system does the rest. Relax…. You have One Touch.

iWave Temperature Sensors

iWave is a contactless in-situ temperature sensor that provides the same accuracy afforded by fiber optic probes. Using wireless iWave technology the sample is being measured, and not the vessel. With the ability to accurately monitor each individual sample you get the best control of the digestion process possible and you can create a report that validates that each individual sample reached the proper temperature.

Available Vessels

The Xpress vessel has been providing high capacity sample preparation for over fifteen years. It uses a simple three part vessel design, making assembly a snap. It is the vessel of choice for environmental digestions including all USEPA methods (3015a, 3051a and 3052) as well as European Norm methods. With a batch capacity of 40 positions this is the vessel choice for a high throughput lab.

  • Easy to assemble 3 piece vessel
  • Digest up to 40 samples for your high throughput needs
  • Ideal for environmental digestions including USEPA & European Norm methods
  • Also digest Foods, Feeds, Fertilizers, Consumer Products, Plant & Animal Tissues

The Xpress Plus vessel is based upon the simplicity of the Xpress vessel but allows for a larger working volume due to the 110 mL vessel volume. The Xpress Plus is designed to run samples similar to the Xpress vessels such as: plant and animal tissues, mixed food samples, consumer products, and industrial hygiene. Up to twenty four vessels can be prepared simultaneously to meet the throughput requirements of most analytical laboratories. 

  • Easy to assemble 3 piece vessel
  • Digest up to 24 vessels for your high throughput needs
  • Digest larger samples than MARSXpress Vessels
  • Broad range of applications

Xpress Plus liners can be combined with glass inserts:
Safe, simple, and high-throughput. Other digestion systems using disposable vessels are slow, require dangerous pressures, and can only digest half as many samples. The new CEM glass vessels revolutionize disposability for a fraction of the cost.

  • Weigh sample directly into the disposable vessel without static interference
  • Prepare a second set while another batch is running
  • Up to 24 samples can be digested simultaneously
  • Dilute samples directly in the glass vessel
  • Load onto ICP autosampler
  • Discard vessel – No washing

The EasyPrep Plus vessels are rugged high performance vessels that are good for preparing a wide variety of difficult to digest organic and inorganic materials. These include many types of oils and polymers as well as ceramics and catalysts.

  • Easy to assemble
  • Ideal for moderate to difficult to digest samples
  • High temperature/high pressure vessel
  • Broad range of applications

The iPrep™ vessel has higher operating parameters than any other vessel and can digest up to twice as much sample per run. Larger samples ensure homogeneity and increase limits of detection, a plus for any lab. 

  • Digest difficult organic samples at higher temperatures to achieve a clear digest
  • Digest up to twice as much sample per run
  • Accurately measure the temperature of every sample with iWave™
  • Patented dual-seal design
