embedding, specimen storage popular for electron microscopy embedding
Current techniques involving the use of acrylic resins and dry ice temperatures for electron microscopy embedding require ultraviolet polymerization in many instances. Gelatin capsules have found a renewed popularity with these applications. Also useful for specimen storage, shipping and carrying of small specimens, apertures, and calibration specimens.
Be sure to pre-dry capsules before use. Flushing with dry nitrogen is recommended before resins are added to the capsules.
Specimens are embedded against the large flat bottom surface of the mold, 7mm in diameter, for improved orientation. A BEEM® size 00 capsule with the tip removed can be inserted part way into the cavity, before filling with the plastic. Blue silicone rubber. Maximum temperature: 218°C (425°F).
Number of Cavities: 12 Numbering Outside of Cavities: 1-12 Mold Size: 97 x 38 x 11mm thick
