Discover SP-D Automated microwave digestion systems
Discover SP-D is the world’s only automated sequential microwave acid digestion system. This system produces a clear aqueous digest for elemental analysis by ICP, ICP-MS, or AA. Since each vessel can have its own method, you can mix and match samples and acids within the automation rack, providing your laboratory great flexibility. Digestion time is 10 minutes or less providing rapid turnaround and the ability to accommodate rush samples. Unattended operation of the system allows your analyst to work on other tasks, thereby improving your laboratory’s workflow.
How it Works
The Discover SP-D digests samples by the use of acids and microwave irradiation. The Discover SP-D is unique because of the small focused cavity which allows for rapid heating and cooling. Active pressure management allows the sample to vent at temperatures and pressures where gasses can effectively be removed while sample and analytes are retained. To increase the throughput of a Discover SP-D, the Explorer Autosampler is available. This is an advanced robotic arm that moves your samples from a rack, to the microwave cavity for digestion, then back to the rack. The arm will move on to the next sample automatically until your programmed run is complete, even pausing its program to accommodate rush samples as necessary. Load up your samples and walk away.
Precise & Efficient Energy Delivery
The Discover SP-D’s Focused™ microwave cavity produces a highly defined and extremely homogeneous microwave field. This cavity design enables the system to process samples faster and more reproducibly than batch style systems.
Faster Digestions, Rapid Cooling
CEM’s patented PowerMAX™ Cooling provides the ability to cool the vessel rapidly and avoid many exothermic reactions that can occur during digestion. In addition, it delivers rapid cooling after digestion, allowing the Discover SP-D to process samples in as little as 10 minutes per sample.
The Industry’s only Actively Venting System
Batch systems use vessels that vent once the vessel reaches a set pressure. With CEM’s patented Activent® Technology, the Discover SP-D automatically measures pressure and controls when the vessel vents. This enables discreet venting at pre-set limits, preventing oss of elements, including volatiles such as mercury and arsenic.

The most versatile acid digestion systems ever made
Discover SP-D systems are truely unique. Their versatility comes from their ability to run one sample by manually loading, or by utilizing the robotic arm (Explorer) to load many samples automatically for you. Whether you’re digesting one sample, or many, a Discover SP-D will quickly and easily digest your samples.
Digest one sample in 10 minutes.
The Discover SP-D can fully digest one sample in only 10 minutes. This provides instant sample preparation for your priority samples.
Digest up to 24 samples in a single run.
For labs who need to digest larger quantities, you can utilize the Explorer autosampler. The Explorer loads the samples for you one at a time until your run is complete. While it works, you’re free to move on to other tasks.
Digest different samples all in one run.
Not only is the Discover SP-D versatile with it’s quantities, it’s also versatile with the types of samples in a single run. Since the SP-D digests samples one at a time, you’ll be able to run different samples, using different acids, under different conditions, all in one run.
An adavanced robotic arm always lends a hand.
What makes a Discover SP-D automatic, is the Explorer Autosampler attachment. Once an Explorer is loaded and the SP-D programmed, the system takes care of the rest for you. Each sample is precisely moved by the arm to the microwave, digested to a clear solution in minutes, then moved back to the rack for cooling.
Discover SP-D 80 Explorer Options
- 24 Position Autosampler
Software that does the hard work for you.
- Real-time display of temperature, pressure, and microwave power
- Pre-installed methods for many sample types
- Sample queues that mix methods and sample types in a single run
- 21 CFR Part 11 Compliant
- Automatically generate a report of run conditions for every sample, not the batch
The Discover SP-D system automatically generates a lab report to verify digestion conditions were met for each individual sample, not of the batch. Temperature, pressure and power graphs are documented, as well as the maximum temperature and pressure, during the digestion.
Weigh, snap, load. Done.
1. Weigh the sample and add acid.
2. Snap on the cap and place in the Explorer Autosampler.
3. Select the method(s) and press “Start”.
After you press the start button, your work is done. The system will do the rest for you and let you know when the fully digested sample is ready.
Set it, and forget it.
Safe to leave unattended.
The Discover SP-D is more than the latest technology for microwave digestion: it is a new concept in sample preparation. Discover SP-D is a sequential, pressurized microwave digestion system that processes samples completely unattended, allowing laboratory staff to tend to other tasks. Just load the autosampler, press play and walk away. The SP-D will do the rest.
Any sample, any acid, in the same run.
A flexible system that gives you a flexible schedule.
Each sample is fully controlled. Every sample has its own method, allowing mixed samples and acid types to be run in a sequence. No more waiting for similar samples for batch processing. Temperature, pressure, and power parameters are captured for every digest and can be graphed for verification.
A Discover SP-D system is fully automated. You can mix different samples that use different acids in the same run. Once you set the preloaded applications and hit play, your work is done. The SP-D finishes the digestion for you and produces a clear digest, ready for analysis.
