Fluorescence Microarray Scanner for DNA & Protein Microarrays Applications in Life Sciences and Diagnostics

Handy, flexible and robust Microarray scanner which provides excellent results.
The benefits from the advantages of our Microarray Scanner MArS :

  • Best price performance ratio
  • Scan four slides simultaneously and save time
  • Peltier-cooled laser modules to get the best scan results at every temperature
  • Up to six emission filters for flexibility at different fluorescence colorants
  • Integrated grey filter to read out barcodes
  • 20-bit dynamic range for gene expression and miRNA
  • Automatic grid finding
  • VerificationKit for the automatic detection and removal of errors so that you can always rely on your measuring results

The MArS is ideal for every laboratory and individual use, whether commercial biochips or self-created microarrays. The MArS offers enough flexibility to read out every microarray slide made of glass or plastics.
In addition, the software SpotScout provides the required values to be able to make scientific and reliable statements.
Why don’t you just test us immediately and send us your biochips – we supply high-resolution images and value tables .

SpotScout Pro

 Microarray analysis software

Enables the automatic evaluation of a wide range of biochip formats

  • Quantifiying and evaluating image data from biochips
  • Powerful algorithms for automatic grid finding
  • Reliable and efficient quality control

Microarray Analysis software 

Daily tasks become significantly easier and are performed much faster due to intuitive interfaces, efficient session management and comprehensive reporting.


Microarray Analysis software

Fully automatic grid finding avoids individual errors and affords reproducibility of results at all times.


Quality control
SpotScout Pro comes with reliable quality assurance functions, such as spot position evaluation, artefact detection and saturation checks.

  • Objective evaluation of the overall quality of a chip
  • Objective evaluation of the individual quality of each spot
  • Avoidance of costly misinterpretation due to experimental artefacts
  • Documentation of each evaluation step

Compatible with a broad range of biochip formats

  • Image formats from microarray scanner MArS and all standard scanners
  • Import of all GAL files

MArS Verification Kit
