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.
