ASP-1000 Automated Specimen Processor

At last – a single instrument that automatically prepares specimens, stains grids, prepares en bloc SEM samples, and does immuno-labeling!  The mPrep™ ASP-1000 adds the efficiency and reproducibility of automation to the advantages of mPrep capsules.  Like no other instrument:


One instrument prepares specimens and TEM grids

No messy resin transfers. TEM and SEM en bloc specimens are processed and embedded in mPrep/s capsules

Complicated protocols? No problem. Simultaneously prepare titrations and controls with up to 72 reagent steps, 576 reagents, and unlimited program steps

Expensive reagents? No problem. Requires only microliters of expensive reagents like antibodies and labels

Identical processing provides comparable results every time

Efficient agitation ensures excellent mixing

Ultra rapid agitation accelerates tissue preparation from days to hours:

Ideal for research and clinical labs. Stop babysitting reagent exchanges! Use for routine and special tasks:

  • TEM specimen fixation, dehydration, and embedding. Simultaneously prepare 8 or 16 specimens
  • SEM specimens including en bloc serial sectioning
  • Grid staining or labeling. Simultaneously prepare 16, 32 or 48 grids
  • Easy set up and clean up
  • Intuitive operation.

Control of Bio Reaction Automation (COBRA) software

  • Pre-written protocols make implementation a breeze
  • New protocols easy to create – just specify reagent, reaction time, and agitation
  • COBRA provides functionality for a wide range of lab personnel to operate the ASP without fear of inducing unintended operator error.
  • Three-tiered access: Administrator, Developer, and Operator
  • Protocols are precise and efficient with much greater reproducibly than is humanly possible.

Using the ASP-1000

1. Select a protocol with the ASP COBRA software, or create a new protocol

2.  Attach mPrep capsules with loaded specimens or grids

3.  Place reagents in microwell plates on the ASP-1000 tray. Optionally seal reagent plates with disposable covers to cut air exposure and prevent evaporation

4.  Press START.  The ASP-1000 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-1000:

– For TEM 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.
