It is an advanced technique for preserving anatomical material.
What does it involve?
It consists of replacing the natural fluids and fats in the tissues with a polymer (such as silicone, polyester, or epoxy resin). Once cured, the specimens become dry, stable, and virtually odorless.
- High anatomical realism.
- Durability for teaching and museum display.
- Safe handling.
- Dehydration: removal of water.
- Impregnation: replacement of the solvent with a polymer under vacuum conditions.
- Polymerization: solidification of the polymer through the action of a hardener.
- Teaching: manipulable specimens for hands-on practice.
- Clinical demonstration: support for students.
- Museography: safe and educational exhibits, enabling comparative study among species using real samples.

Plastination produces durable, dry, and touchable specimens that require no special protection or storage.
These plastinated samples have transformed anatomical teaching and research, providing a learning experience that traditional preservation methods could never achieve.
They enable students and health professionals to study the internal structure of the animal body with exceptional precision, making the learning and understanding of anatomy clearer and more engaging

Do plastinated specimens release toxic substances?
No.
How long does the process take?
It depends on the size of the specimens and the type of tissue — from a few weeks to several months. The impregnation and curing stages are usually the longest.
Can they be handled and cleaned?
Yes. They can be handled carefully and gently cleaned, avoiding prolonged humidity and direct heat.
What are the differences compared to formalin preservation?
Plastination: dry, durable specimens.
Formalin: liquid preservation medium, high toxicity, and requires protective measures.
