Sample Preparation for MALDI Imaging - the Tissue MALDI Sprayer M5


The patented top model!

Heatable Spray Nozzle!

The new advanced Tissue MALDI Sprayer M5 builds on the well established characteristics of the TM-Sprayers M3 , but is more powerful and offers wider processing potential.

The patented spray technology with its heatable spray nozzle allows the use of high flow rates, resulting in fast processing times. Faster cycles of 2 to 8 minutes per slide are possible.

The completely new casing, ultrafast movement of the spray nozzle (4 x faster), the drawer system for easy loading
of samples and the ensuing improved user-protection and better adjustment of the sample plates, as well as the heatable sample tray, all enhance and accelerate the MALDI-MS sample preparation processes. There is an integrated pump control, the waste disposal has been optimised and it is possible to access the inline filter easily.

The finest spray mist (very small matrix droplets, 1-3 micrometers) of the M5 allows extremely constant, fine and precise matrix coating, which is decisive for high-resolution imaging.

More than 30 validated protocols for trypsine and most matrixes (e.g. SA, CHCA, DHB, DAN, 9-AA, DHA, CMBT, THAP) are available as well as for trypsine digestion from FFPE (formalin-fixed and subsequently paraffin-embedded tissue).
