arrow13mPrep™ System for Specimen Preparation and Grid Staining

Submit a follow up request

The mPrep™ System saves you effort while protecting and keeping track of valuable samples. The system features two types of purpose-built, microliter-volume capsules – one for specimens, the other for grids. Capsules attach to standard pipettors, which are used to conveniently deliver reagents in measured amounts.

Users get consistent sample preparation with almost no direct handling of specimens and grids. Once the tissue or grid is in its own, labeled capsule, you don't have to touch it again during processing. It is safe, easy-to-handle and clearly labeled. The small, enclosed capsule, reduces reagent consumption. The system adapts to any protocol for biospecimen preparation, grid staining or immuno-labeling. Multi-channel pipettors enable users to increase throughput, with virtually no extra effort. Read more to see how these cleverly designed capsules work!

arrow12mPrep/s™ Specimen Processing Capsules

mPrep/s capsule with specimenmPrep/s

mPrep/s Insertion Tool

mPrep/s™ capsules allow users to fix, dehydrate and embed specimens in a single vessel. They can be used in two ways. The first method is to entrap specimens in the bottom of the capsule using the removable, adjustable screen with the hand-held Insertion Tool (85010-03). The second method is to flex the screen open using the mPrep/s™ Workstation* (85010-06). With the screen opened, the user places a specimen in the screen and orients it to the desired position within the capsule. Once the screen closes on the specimen, it is held in place throughout fixation, embedding, and sectioning. No additional embedding molds are required, and the capsule itself easily fits in the microtome chuck. This capsule is highly recommended for transmission and scanning electron microscopy, but can also be used for any sample preparation.

mPrep/s™ capsules are available in storage boxes or in bulk. The hand-held Insertion Tool (85010-03), the Workstation* (85010-06), and additional recommended accessories for use with the mPrep/s™ capsule are located below and at the end of this page.

* The Workstation is required to make use of the orientation feature of the mPrep/s™ screen.

arrow12mPrep/g™ Grid Processing Capsules

Each capsule can hold one or two TEM grids securely for staining, immuno-labeling and labeled storage. Grids are protected from loss, misidentification, and damage. Grid-tite™ slots keep grids safe even if an open capsule is dropped.

Grids require handling only twice: when inserted into capsules and when placed in the TEM.

Using a multi-channel pipettor, processing up to 24 grids simultaneously takes no more effort than a single grid. Reagent consumption is as little as 20µl per grid. The chance of grid damage or loss is greatly reduced using these capsules. See mPrep/g™ Pipettor Kits (85010-07 to 85010-10) and additional accessories below.

arrow12mPrep/s™ WorkStation for TEM and SEM

mPrep/s workstation

Everything you need to work efficiently while preparing your samples using mPrep/s™ capsules is easily accomplished with the mPrep/s™ WorkStation. Simply load the capsule onto the built-in insertion tool at the center of the workstation, detach the screen from the capsule, use the lever to open the screen and insert the specimen. Then release the lever and re-attach the capsule. Once loaded, the sample requires no additional handling – even for TEM embedding or SEM mounting.

The mPrep/s™ Workstation's polyethylene surface minimizes dulling of dissection tools and is fully immersible for easy cleaning between uses. Molded into the surface are 12 dissection wells to organize your specimens and keep them wet if desired. At the back, 12 capsule wells and 3 screen holders conveniently hold these prior to use. On either side of the workstation, a total of 24 capsule wells can hold loaded capsules and keep them wet while loading into the channels of the pipettor. Single and multichannel pipettor kits are sold separately. Additional recommended accessories for use with the mPrep/s™ Workstation are located the end of this page.

Features

  • Specimens may be oriented using several methods
  • Streamlines specimen processing from dissection to reagent processing
  • Once loaded in capsules, specimens are not touched again – even for TEM embedding or SEM mounting
  • Dissect and load specimens wetted by buffers or fixatives
  • Directly load capsules onto pipettor from Workstation

Applications

  • Capsule-based Processing of Biological Tissue for TEM
  • Biological tissues – fix and critical point dry (CPD)
  • Bio tissue cryo-facing
  • Polymer cross-section preparations
