mPrep™ ASP™ instruments automate and accelerate biological sample preparation for the highest-quality TEM and 3D volume EM (vEM), including serial block, focused ion beam and array tomography SEM.
Every mPrep ASP is purpose built for preparing specimens with aggressive EM reagents, solvents, and even viscous resins.
ASPs prepare TEM and vEM specimens including tissues, cell pellets, organoids and cell adhesion substrates (e.g. coverslips), and do on-grid and pre-embedding immuno-gold labeling.
Specimen counts vary? Efficiently prepare just one specimen, or prepare up to 128 TEM or up to 64 vEM specimens at one time.
Complicated protocols? Simultaneously prepare specimens or grids with up to 8 different protocols, with up to 72 reagent steps and 576 different reagents, and even more.
Expensive reagents? No problem. Use as little as 40 microliters per reagent step.
Identical processing with unique microfluidic-directed-flow agitation for consistent and efficient reagent infiltration.
Time, hands-on effort, and reagent efficiency. Save days of work while cutting reagent consumption by half or more. Prepare from aldehyde rinse-out to ready for resin curing in just hours.
Published Results. See how 5 different labs use ASPs for efficient TEM and vEM workflows in these two reports: Microscopy today 2025 and Microscopy Today 2024.

- vEM – Serial block face, FIB-SEM, and Array Tomography prep of brain and breast cancer in 7 hours – Methods in Cell Biology volume 177
- vEM – FIB-SEM & Serial block face – breast cancer specimens in 5 hours instead 2.5 days.
- vEM – Serial block face – brain prepared in a day – Winner 2020 Diatome Poster Award
- vEM – Serial block face – heart in 8 hours
- vEM – Serial block face – planaria in less than a day – Winner 2017 Diatome Poster Award
Stop babysitting reagent exchanges!
- TEM specimen fixation, en bloc staining, dehydration, and embedding
- Immunolabeling – On grid and pre-embedding (en bloc)
- vEM specimen fixation, staining, dehydration, and embedding
- SEM specimen fixation and dehydration
- Easy set-up and clean-up.
Easy Intuitive Protocol Creation
- Pre-written protocols for TEM and vEM
- Create new protocols or customize existing protocols – specify reagent, reaction time, agitation, and reagent temperature (ASP-2000 and ASP-2500)
- Two-tiered access: Operator and Developer
- Precise and efficient protocols with greater reproducibly than humanly possible.
- Protocols are easily shared with any ASP-equipped lab with any ASP model.
Using ASP processors
1. Select a protocol (or easily create a new protocol)
2. Attach mPrep capsules with loaded specimens or grids
3. Place reagents in microwell plates on the ASP tray. Optionally seal reagent plates with disposable covers to cut air exposure and prevent evaporation
4. Press START. The ASP does the rest:
– mPrep capsules move from reagent to reagent
– Reagents are drawn into mPrep capsules for the specified time
– Agitation flows reagent in and out of capsules for excellent mixing
– mPrep capsules punch through optional reagent covers. Reagents are always fresh
5. When the protocol is completed, remove capsules from the ASP:
– For TEM and vEM embedding there is no messy handling of specimens in resin. Eight resin-filled mPrep/s capsules are simply transferred to the oven to cure the resin
– For grids, mPrep/g capsules are removed and stored in an mPrep Capsule Grid box. No tedious handling of grids
– For SEM preparation simply transfer capsules directly to the CPD holder with no direct specimen handling.
