Histology Protocols with Absolute Alcohol

Standard Histopathological Processing

Initial fixation: 10% buffered formalin for an appropriate length of time
Gradual dehydration: Increasing alcohol battery (70%, 80%, 90%, 95%)
Final dehydration: 2-3 baths with EasyPath Absolute Alcohol (essential)
Diaphanization: Xylol for complete tissue clarification
Impregnation: Paraffin melt for definitive inclusion

Staining Techniques with Absolute Ethyl Alcohol

Efficient dewaxing: Absolute alcohol completely removes the paraffin, followed by a decreasing alcohol battery for controlled hydration.

Optimized histological staining: Suitable preparation for Hematoxylin-Eosin and special stains, ensuring accurate cell visualization.

Permanent mounting: Absolute alcohol prepares blades for permanent mounting with long-lasting results.

FAQ – Frequently Asked Questions about Absolute Alcohol

Is EasyPath 99.5% absolute alcohol safe for laboratory use?

Yes, when handled properly with appropriate PPE (solvent-resistant gloves, goggles, filter masks) and in a well-ventilated environment. The product meets all safety standards (ABNT-NBR 14725) for professional use.

What is the difference between absolute alcohol and ordinary alcohol for histology?

Absolute alcohol is 99.5% pure (practically anhydrous) and is essential for the complete dehydration of tissues. Common alcohols have a higher water content and are unsuitable for critical stages of histological processing.

How to store anhydrous ethyl alcohol correctly?

Keep in original airtight container in a dry, cool and well-ventilated place, away from sources of heat, ignition and oxidizing agents. Room temperature and atmospheric pressure are suitable.

Is EasyPath absolute alcohol compatible with automatic processors?

Yes, our formulation is fully compatible with automated histological processing equipment and complies with the strictest tissue dehydration protocols.

What precautions should I take when disposing of it?

Never dispose of in ordinary waste or sewage. The product must be treated as hazardous waste in accordance with current environmental legislation (CONAMA 005/1993, ABNT-NBR 10.004/2004). Incineration or authorized reprocessing routes are recommended.
