FAQs

What is Lab Pro Triethanolamine used for?

Lab Pro Triethanolamine is used as a buffering agent, emulsifier, and chemical intermediate in laboratory and research settings. Its combination of amine and hydroxyl groups makes it useful in formulations requiring pH control, emulsification, or nitrogen-containing reactants.

What makes triethanolamine suitable as a buffer?

Triethanolamine has a useful buffering range between pH 7.3 and 8.3. This allows it to stabilize mildly alkaline systems, making it valuable in laboratory solutions, formulations, and reactions that require controlled, consistent pH.

Is Lab Pro Triethanolamine water-soluble?

Yes. Lab Pro Triethanolamine is completely soluble in water, allowing for easy preparation of aqueous solutions and uniform mixing in laboratory formulations, reactions, and buffer systems without precipitation or phase separation.

What is the purity level of this product?

This product has a minimum assay of 98%, meeting reagent-grade specifications. The high purity supports reliable performance in laboratory, analytical, and research applications where consistent chemical composition is required.

How should triethanolamine be handled and stored?

Triethanolamine should be stored at ambient temperature in a tightly sealed container. Handle using standard laboratory safety practices, including appropriate personal protective equipment, to avoid skin or eye contact during use.
