Automated Microwave Digestion System
Discover SP-D Clinical

Digest a clinical sample in under 6 minutes.



Fast and remarkably simple, the Discover® SP-D™ Clinical is specifically designed to digest small samples for clinical applications. This automated system will optimize your laboratory workflow.


  • Most digestions complete in under 6 minutes (including cooldown)
  • Automatically loads and unloads samples
  • Temperature and pressure control of every sample
  • Documentation of every sample
  • Simple-to-use vessels with snap-on caps


How it Works

discovered clinical weigh image


Just weigh, snap, load, and you’re done.

1. Weigh the sample and add acid

2. Snap on the cap and place in the system

3. Select the method(s) and press “Play”

After you press the play button, your work is done. The system will do the rest for you and let you know when the fully digested sample is ready.



Unique technologies that make your work easy.

Precise and Efficient image

Precise & Efficient Energy Delivery

The Discover SP-D Clinical’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 reproducible than batch systems.

NoLossofVolatiles image

No Loss of Volatile Elements

Batch systems use vessels that vent once the vessel reaches a set pressure. With CEM’s patented Activent® technology, the Discover SP-D Clinical automatically measures the pressure and controls when the vessel vents. This enables discreet venting at pre-set limits, preventing loss of elements, including volatiles such as mercury and arsenic.

FasterDigestions image

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 Clinical to process samples in as little as 6 minutes per sample.

discovered clinical software image

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 Clinical system automatically generates a lab report to verify digestion conditions were met for each individual sample, not the batch. Temperature, pressure, and power graphs are documented, as well as the maximum temperature and pressure during the digestion.




The first ever digestion system specifically for clinical throughput.

6Minutes image

Digest One Sample In 6 Minutes

Don’t waste time batching samples. Discover SP-D Clinical digests samples one at a time, giving you one fully digested and cooled sample in only six minutes. Load the 48-position auto-sampler and let the system digest 10 samples an hour while you tend to other tasks.

RushSamples image

Digest A Rush Sample Immediately

The advanced Synergy-D Clinical software will allow you to interrupt a pre-programmed run to accommodate a rush sample. In just about 6 minutes you will have a digested sample in hand ready for analysis, then the software will resume running as programmed.

Flexibility image

Discover SP-D Clinical Gives You Flexibility

Digest up to 48 small clinical samples, completely unattended. Discover SP-D Clinical gives you the flexibility to prepare different sample sizes, types and acids within one batch.

Phoenix Ease of Use image


Digest small samples with low volume vessels.

The Discover SP-D Clinical was designed specifically to digest small clinical samples. Digest samples as small as 5 mg or up to 100 mg in one of the clinical vessels.

Vessel Size
Minimum Acid Volume
Maximum Acid Volume
4 mL 0.5 mL 1.5 mL
10 mL 1.0 mL 4.0 mL

Snap-on Caps

There’s no need for clamps or torque wrenches.

Our patented, and easy-to-use snap-on caps eliminate the need for clamps or torque wrenches. With just the push of a thumb, the caps will be safely secured and ready for digestion.

Process 48 clinical samples completely unattended.

Load up to 48 samples in the autosampler rack and the Discover SP-D Clinical does the rest. The system sequentially loads each sample into the microwave, digests it to a clear solution in minutes, then returns it to the rack, after cooling, freeing you to leave the system running unattended so that you can tend to other tasks in the lab, or let it run overnight and start your day ready for analysis.

discovered clinical Flexibility image


Mix your samples, vessels, and acids.

  • Digest any clinical sample (as small as 5 mg)
  • 4 or 10 mL vessels can be run with different acids, in the same batch
  • Fully documented pressure and temperature control

To the left is an example of how an SP-D Clinical could be loaded with a variety of samples requiring unique acids and temperature settings for the same run. The SP-D Clinical can handle it, giving you flexibility in your work.


Common Applications
