What is the duration for the pure dioxane solution in Grauper's method?

• A. 1 hour
• B. 2 hours
• C. 15 minutes
• D. 45 minutes

Answer: (A)

In Grauper's method for tissue processing, the pure dioxane solution is critical for dehydrating specimens. The recommended duration of 1 hour allows sufficient time for the dioxane to effectively penetrate and replace water within the tissue, a process that is essential for subsequent embedding and sectioning. Dioxane acts as a dehydrating agent, and a brief exposure might not allow complete dehydration, leading to potential artifacts in the histological preparation. A 1-hour duration strikes a balance between thorough dehydration and maintaining tissue integrity. Shorter exposures, such as 15 minutes, may be inadequate for effective dehydration, while longer durations, like 2 hours or 45 minutes, could lead to over-dehydration, which may compromise tissue morphology. Therefore, the optimal timing for using pure dioxane in Grauper's method aligns with the established guideline of 1 hour for maximum efficacy in tissue processing.
