Introducing the mPrep System

The mPrep™ System uses mPrep capsules to prepare specimens and grids for electron microscopy and other applications.

Use mPrep capsules with the programmable mPrep ASP-1000 Auto Specimen Processor for “hands-off” preparation of specimens and grids with any protocol.

mPrep capsules connect to lab pipettors just like pipette tips for convenient processing in any lab.

Expands lab capabilities

  • Automated “walk away” rapid tissue processing
  • Automated immuno-gold labeling
  • Adaptable and flexible
  • Reproducible results

Solves common problems

  • System efficiency reduces tedium
  • Orient specimens in seconds
  • Protect samples from damage and contamination
  • Minimize human touches

Adapts to unique challenges

  • A core lab does automated overnight immunogold grid labeling
  • An infectious diseases lab reproducibly prepares pathogenic viruses in BSL3/4 biocontainment
  • Tissues prepared for serial block face SEM in 1 day

The mPrep System is the right choice

mPrep/s capsules

mPrep/s capsules entrap specimens for transmission and scanning electron microscopy and other sample preparation. Capsules hold specimens throughout fixation, embedding, and sectioning.


The mPrep Workstation orients specimens in mPrep/s capsules and streamlines workflow from dissection to reagent processing.


Encapsulated specimens are protected from loss, misidentification and damage. Quality reproducible results are achieved with a fraction of the effort.

mPrep/g capsules

mPrep/g capsules hold TEM grids throughout staining, immuno-labeling and storage. Grids are protected from loss, misidentification, and damage.


Grids may require handling only twice: when inserted into capsules and when placed in the TEM. Grid-Tite™ slots keep grids safe even if an open capsule is dropped.


Reagent consumption is as little as 20 μl per grid.  You may never lose or damage a grid again.
