To prevent paraffin block cracking, the following measures can be taken:
Proper dehydration: Ensure thorough dehydration of tissue samples to avoid residual moisture. Gradual cooling: Allow the paraffin block to cool gradually to minimize the formation of stress fractures. Quality paraffin: Use high-quality paraffin with appropriate melting points and minimal impurities. Embedding techniques: Employ meticulous embedding practices to avoid air bubbles and ensure proper tissue orientation.
