Peel-A-Way® Embedding Mold (Truncated - T12) is a disposable polyethylene embedding mold designed to peel away from the solidified embedded block. The unique construction eliminates the need for release agents and block trimming, helping save time during embedding and sample preparation workflows.
These molds are useful for plastic, frozen, and epoxy embedding and can be used with Polyfreeze, JB-4, GMA, MMA, and epoxy systems. The T12 truncated format is especially useful for frozen tissue workflows where defrosting during transfer to a cryostat is a concern.

Applications
Plastic Embedding
Used in plastic embedding workflows where clean release from the solidified block is needed without additional release agents.
Frozen Tissue Embedding
Especially useful for frozen tissue preparation where defrosting during transfer to a cryostat may be an issue.
Epoxy Embedding
Compatible with epoxy embedding systems for laboratory sample preparation and microscopy workflows.
JB-4, GMA & MMA Embedding
Can be used with JB-4, GMA, MMA, and related embedding media in histology, microscopy, and materials preparation workflows.
Compatibility & Workflow Considerations
-
Compatible embedding systems: Polyfreeze, JB-4, GMA, MMA, and epoxy
-
Release method: Polyethylene mold peels away from the solidified embedded block
-
Workflow benefit: Reduces the need for release agents and block trimming
-
Format: Truncated T12 mold for selected embedding and sectioning workflows
-
Performance factors: Final release and block quality depend on embedding medium, curing or freezing conditions, sample type, and handling technique
Evaluate mold performance under the intended embedding medium, sample type, and downstream sectioning workflow.
Preparation Tips
- Select the mold size and geometry appropriate for the tissue, specimen, or embedded sample.
- Fill molds carefully to minimize bubbles and uneven block formation.
- Allow the embedding medium to fully solidify, cure, or freeze before removing the mold.
- Peel the mold away from the block using controlled handling to preserve block edges and sample orientation.
- Document embedding medium, cure or freeze conditions, sample orientation, and sectioning workflow for reproducible results.
Handling & Storage
- Store in a clean, dry area before use.
- Protect unused molds from dust and contamination.
- Use clean handling practices to avoid introducing debris into the embedded block.
- Follow the handling guidance for the selected embedding medium, resin, or freezing compound.
