mPrep/s Workstation

mPrep/s™ Workstation efficiently loads and orients specimens into mPrep/s capsules.  Use for TEM and SEM.

 

Accurate orientation. Specimens may be oriented using several methods

Efficient workflow. Streamlines specimen processing from dissection to reagent processing

Reduce handling. Once loaded in capsules, specimens are not touched again for TEM embedding or SEM mounting

Easy dissection. Single focal plane keep specimens in focus during dissection and when loading specimens in capsules

Wet samples. Dissect and load specimens wetted by buffers or fixatives

Efficient reagent processing. Directly load capsules onto pipettor from Workstation


Organized for efficient workflow


Product Description

  • Durable, corrosion-resistant materials for long service with saline, buffers and aldehyde fixatives. Can be fully immersed for cleaning.  Safe cleaning with detergents, bleach and alcohol
  • Top cutting surface is:
    • Soft high density polyethylene (HDPE) that minimizes dulling of fine dissection tools
    • Low glare and lightly textured surface for optimal visibility and easy specimen handling
    • Top is easily replaced if it becomes marred with cuts after long use
  • 6 dissection wells to organize and prepare specimens, and keep them wet
  • 12 capsule wells and screen storage in back holds 12 capsules until used
  • 24 capsule wells (12 per side) to hold mPrep/s capsules after loading with specimens and to keep them wet. Spaced for direct attachment of capsules onto 8 and 12-channel pipettors
  • Rounded front edge provides comfortable use
  • Feet adjust to change height. Adjust for comfort and to straddle many dissecting microscope bases
  • Precision mechanism is fully adjustable.

Prepare the specimen

  • Trim and dissect on Workstation surface
  • Use shallow wells to keep specimens organized
  • Add water or fixative to wells during dissection

Load screen (and unoriented specimens)

  • Insert mPrep/s screen into Workstation insertion tool
  • Engage screen tabs into insertion tool flanges

Orient specimen – Back Pinch Method

  • Press Workstation lever to open screen
  • Place back end of specimen into screen opening
  • Release lever to pinch specimen

Encapsulate specimen

  • Slide capsule down to hold specimen in place
  • For Back Pinch Orientation method leave space above specimen

Remove capsule from Workstation

  • Rotate capsule counter-clockwise to disengage screen from Workstation insertion tool
  • Lift capsule off Workstation

Set aside encapsulated specimen

  • Place capsule into a Workstation well
  • Add fluids to wells to keep specimens wet
  • Load capsules directly onto pipettor for reagent processing

mPrep workstation applications

Specimen preparation for Serial Block Face SEM (SBEM) and other volume EM (vEM) methods (e.g., FIB-SEM), requires multi-day protocols to provide the necessary very extensive heavy metal staining. The mPrep ASP automates these protocols and executes them in much less time.

Tissue processing and orienting specimens for sectioning is time consuming. mPrep/s capsules accurately orient specimens in seconds using the mPrep Workstation. Capsules used with pipettors enable simultaneous and controlled reagent processing.

Processing tissue for SEM can be tedious. There is potential for specimen damage due to contact with labware and critical point dryers. Orienting and mounting brittle CPD prepared tissues is challenging. With mPrep/s capsules specimens are protected and can be oriented prior to CPD processing.

Multiple cryogenic manipulations are required to rapidly freeze and orient tissue specimens for cryo-facing and SEM. With mPrep/s capsules, tissue samples are oriented prior to freezing and secured in the capsule through cryo-facing and SEM mounting.

Embedding and orienting polymers for cross sectioning is challenging: Particles are difficult to entrap and orienting fibers and films is time consuming. With mPrep/s capsules particles are easily entrapped, and fibers or films are oriented in seconds using the mPrep Workstation. Once loaded in mPrep/s capsules, multiple specimens can be simultaneously embedded.
