CEM | Microwave Synthesis




Technology

Synthetic organic chemistry, built on functional group conversions and carbon-carbon bond formation, has long benefited from microwave heating. Microwave reactors have become the industry standard for methodology development and total synthesis because they work better than conventional bench methods, providing: Faster reaction times, Access to different product distributions, more accurate and precise reaction control, faster and more simple reaction setup. Inorganic chemistry from catalyst preparation to solid-state synthesis can take advantage of faster reaction times and improved yields using microwave energy. Compared to conventional heating, microwave energy can also furnish: Unique morphologies and phases, access to novel reaction pathways and lower polydispersity using volumetric heating Useful for both monomer synthesis and subsequent polymerizations, microwave energy provides unique reaction control to influence molecular weight and polydispersity characteristics. Perform reactions in minutes or hours rather than days with the ability to add more monomers, catalysts, or other reagents during the reaction.

Mars 6

Better digestions for better analyses
Now with iWave & iLink

For over 30 years chemists have trusted CEM to provide the highest quality microwave digestion systems for their laboratories. The MARS 6 is simply the easiest to use, safest and most intelligent system on the market. It is the only system that uses integrated sensor technology to recognize the vessel type as well as the sample number then apply the appropriate amount of power to ensure the highest quality digest. With options for remote system control and contactless all vessel temperature control, the MARS 6 is ready to handle your most difficult samples.

• Contactless in-situ temperature measurement
• Sensors that detect vessel type and count
• Hundreds of preprogrammed methods
• Easy to use vessels for every application

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 MARS EXPRESS 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

This Xpress plus vessel is based upon the simplicity of the MARSXpress vessel but allows for a larger working volume due to the 110 mL vessel volume. The MARSXpress Plus is designed to run samples similar to the MARSXpress 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

Discover SP

Discover SP


A New Generation of Microwave Synthesis.
The Discover® SP System is the newest member of the Discover product line and the premier microwave synthesis system on the market. The Synergy™ software and onboard controls of the Discover SP make it the easiest-to-use microwave system, even for those who have little or no experience with microwave technology in the laboratory, while still maintaining all of the advanced programming options requested by skilled microwave users. This new system has all of the features for which the Discover series is known, an enhanced heating capability, and CEM’s new ActiVent® Technology, all in one compact, simple-to-operate system. The Discover family of Microwave synthesis instruments have the following capabilities:

  • Patented Focused single mode cavity
  • Vessels 10 and/or 35 ml
  • Self-tuning cavity
  • Continuous power generation and control of power supply from 0 to 300 WATT
  • Removable spill cup makes clean up fast and easy
  • Multispeed magnetic stirring
  • Automated power control based on temperature feedback
  • With the patented PowerMax™ technology (simultaneously cooling while heating)
  • Available options:

  • Automation
  • Add the Explorer hybrid 12 or Explorer 48 to queue up reactions and let them run unattended.
  • Camera
  • The optional integrated camera allows you to see the changes occurring during your reaction. It's the perfect tool for documentation and publication support.
  • CoolMate Low-Temperature Option
  • The CoolMate is the only commercially available microwave synthesis system designed to perform reactions at sub-ambient temperatures. Reactions such as lithiation, carbohydrate synthesis, and other temperature-sensitive chemistries can now benefit from the use of microwave energy. Use the power of microwave energy to accelerate reactions even at temperatures as low as -80 °C
    Gas Addition Kit
    The Gas Addition accessory is the only system specially designed for reactions involving gaseous reagents. Perform hydrogenations, carbonylations, or other reactions with gaseous reagents or simply use the vessel to ensure an inert atmosphere during microwave irradiation. This system allows you to purge the reaction vessel and back-fill with a gas. During the reaction, the gas source is completely shut off from the microwave, thereby ensuring your safety at all times.

    The 80 ml vessel
    The 80-mL vessel allows a working volume up to 50 mL and operation at elevated temperatures and pressures (250 °C and 250 psi (17 bar).
