PTFE Embedding Mold

Machined from PTFE block. This mold offers flat embedding for most resins, including LR White®, LR Gold®, JB-4, Immuno-Bed and Lowicryl®. This PTFE Flat Embedding Mold can be used for both UV/low temperature and thermal cure, and may be used as a substitution for the silicone molds. The individual cavities are pre-shaped to reduce block trimming.

Available Options:


For curing anaerobic material, we recommend using Aclar® film, cut-to-size of the mold and lower on top of the mold after you ‘just over-fill’ the cavities with embedding resin. Due to the flexibility of the PTFE, you just bent the mold to pop out the cured resin blocks. After all the cast blocks have been removed, reinsert the mold to its holder to re-shape the mold. The mold holder is machined from aluminum and anodized black.

Mold with 18 cavities, each cavity measures 5 mm W x 14 mm L x 4 mm D

Overall mold measures: 5½” x 3″ x ¼” (140 x 50 x 6 mm)

Mold is available as a set (includes one PTFE mold and one aluminum holder).
