Product Description

JB-4® Plastic Block Holders are designed for resin embedding workflows. The matte surface allows blocks to be marked easily, while the large center hole helps prevent bubble formation during embedding.

The holders fit securely onto molding cup tray cavities and attach to reusable chucks designed for commonly used microtomes, including the JBA Chuck.

For JB-4® glycol methacrylate embedding, see the JB-4® Embedding Kit.
