mPrep/s™ capsules allow users to fix, dehydrate and embed specimens in a single vessel. This capsule is highly recommended for transmission and scanning electron microscopy, but can also be used for any sample preparation.

• 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 (76439-618). The second method is to flex the screen open using the mPrep/s™ Workstation (76439-624). 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.

The Workstation (76439-624) is required to make use of the orientation feature of the mPrep/s™ screen. mPrep/g™ processing 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 20 µl/g.
