Specimen Embedding Capsules

  • Specimen Embedding Capsules
    the standard in the EM field

    BEEM® pioneered the development of certain TEM specimen preparation products. Their embedding capsule remains a standard product for routine EM. Preformed capsule tips in the shape of a truncated pyramid with a flat 1 x 1 mm face at the end reduce trimming time and produce cleaner surfaces.

    • A hinged cap is used for closure or may be used for making flat-tipped molds.
    • Hardened blocks may be removed using a BEEM® Capsule Press. Filling the capsules is made easier with BEEM® Capsule Holders (#132, 132B).
    • Capsule size 00 is preferred, but for specimens with certain shapes (long, particulate) see BEEM® bottle-neck or conical capsules.
    • For smaller specimen sizes, a smaller capsule size is available.
    • Polyethylene capsules have long been preferred in standard EM resin preparation. Acrylic resins and UV polymerization technology have increased the use of gelatin capsules.
