How to Introduce Ethanol in Your School Lab

If you teach chemistry, biology, or even basic lab techniques, chances are you’ve come across experiments that call for ethanol. It’s one of the most versatile and widely used chemicals in educational settings, playing a key role in everything from flame tests to DNA extraction. But before adding it to your school’s chemical inventory, there are a few important considerations every science educator should know.

At Lab Alley, we work closely with schools and educators to help them introduce lab-grade chemicals like ethanol safely, responsibly, and in full compliance with school policies. Here’s what you should consider before placing your first order.

In this blog, we’ll explain what ethanol is, why it’s used in school labs, and the key steps to introduce it safely, responsibly, and in compliance with school policies.

What is Ethanol and Why is it Used in School Labs?

Ethanol, also known as ethyl alcohol, is a clear, flammable liquid that serves a wide range of purposes in laboratory environments. In schools, it’s especially popular for:

  • Disinfecting lab tools and surfaces
  • Acting as a solvent in biology and chemistry experiments
  • Fueling combustion demonstrations or alcohol burners
  • Helping extract plant pigments or DNA

Ethanol comes in various concentrations, such as 70 percent for disinfection or 95 percent for more advanced applications. Lab-grade or denatured ethanol is often preferred in educational settings because it is treated to discourage misuse while maintaining its chemical usefulness.

Understanding Permits and School Policies

Before purchasing ethanol, it’s important to understand your school’s guidelines and any local or state regulations that may apply. Depending on the concentration and quantity, your school might need to:

  • File a chemical storage permit
  • Limit how much ethanol is stored on-site
  • Designate a licensed staff member to oversee chemical use
  • Notify your fire marshal or facilities department

Some school districts have policies about storing flammable liquids or require you to document their intended use. If you are unsure, check with your department chair, science coordinator, or administrator. It is always better to get approval in advance.

Safety Guidelines for Handling Ethanol in the Classroom

Although ethanol is relatively safe when used correctly, it does come with important handling guidelines. Since it is both flammable and volatile, classroom use should follow strict safety practices. Here’s a quick checklist:

  • Only use ethanol in a well-ventilated space
  • Keep it away from heat sources and open flames when not in active demonstrations
  • Ask students and instructors to wear goggles, gloves, and lab coats
  • Store ethanol in a flammable-safe cabinet that locks
  • Ensure bottles are clearly labeled and include hazard information

Always prepare for the unexpected. Know your school’s spill response procedures and have absorbent materials on hand just in case. And of course, never leave open ethanol containers unattended in a student-accessible area.

Disclaimer: Ethanol is intended for educational or professional use and should only be handled by trained personnel following appropriate safety guidelines.

Sourcing Ethanol Responsibly

When it comes to classroom chemicals, sourcing matters. You want a supplier that understands school-specific needs and offers products with full documentation. Look for:

  • A clear product label specifying concentration and grade
  • Access to up-to-date Safety Data Sheets (SDS)
  • Verification that your school is authorized to purchase and store the material
  • Options for smaller quantities suited to educational use

Avoid consumer-grade or off-brand ethanol from retailers lacking proper documentation or support. Lab-grade ethanol should always come from a certified supplier who prioritizes compliance, quality, and safe packaging.

Final Thoughts

 Ethanol is a classroom staple that enriches your lab experiences with dynamic demonstrations and hands-on activities. With the proper safety practices, documentation, and oversight, you can integrate ethanol into your lab confidently and responsibly.
