This 24 cavity mold produces a block similar to the embedding capsule block but with the following advantages: * Resin polymerizes better in silicone rubber than in polypropylene or polyethylene - the rubber heats more evenly and retains the heat better than in plastic.
- It is easier to see inside the well when centering the specimen in the tip.
- It is easier to remove the block from the well. There is no need for razor blades or press devices.
- The finished blocks have finer tips so when you trim deeper into the block the face doesn't increase in size rapidly; therefore, constant retrimming is not necessary

This mold accommo dates longer pieces of tissues (muscle, skin biopsies, and many plant specimens)
- Easy to embed long specimens and orient them properly. The tissues lie flat in the well; therefore, no horizontal trimming is needed.
- It is ideal for any specimen that needs immediate sectioning (e.g. cell monolayer). 24 cavities

This mold is designed primarily for embedding cell culture specimens grown either directly on the bottom of a dish or onthe filter when cross sections of the cells are needed:
- Cells grown on petri dishes are cut into strips just before the propylene oxide dehydration step; when Propylene Oxide is added, the strips lift right off the bottom.
- When the strips are ready for embedment, they are rolled on an applicator stick into a wad and gently lowered into the well (the strips should not float).
- Many cells can be examined in cross section.
- There is no need for trimming - sectioning can begin immediately.
- The curved side makes the tip very strong in spite of its thinness.
- Easy detection of a strip of cells.
- The label is placed on the round part so as not to interfere with the specimen.
- 24 cavities.

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.
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 5mm W x 14mmL x 4mm Deep
Overall mold measures: 5 ½” x 3” x ¼” (140x50x8mm)
Mold is available as a set (includes one PTFE mold and one aluminum holder).

This invention is a mold used for embedding mammalian cells in monolayer culture in preparation of sectioning for light or electron microscopy. Tissue culture monolayer embedding molds eliminate the need for traditional BEEM® capsules. The improved molds can be used to transfer the majority of cells from the entire surface of a cover slip to avoid losses of large amounts of cellular information occurring only randomly. In addition, other problems such as surface blemishes caused by air entrapment associated with BEEM® capsules are eliminated.
- The mold yields several individual blocks of resin from a single slip-cover.
- The resin blocks fit directly into a chuck for flat specimens.
- The embedded surfaces are free from blemishes caused by entrapped air.
- The mold uses a minimum amount of resin.
