FAQs

What is Lab Pro Urea ACS used for?

Lab Pro Urea ACS is commonly used in laboratory and biochemical applications such as protein denaturation, solubilization, and renaturation studies. It is also used to prepare analytical standards, support research on nitrogen metabolism, and serve as a reagent in chemical manufacturing workflows.

Why is urea effective for protein denaturation?

Urea disrupts hydrogen bonding and weak non-covalent interactions in proteins, causing them to unfold. This makes it valuable for studying protein structure, refolding experiments, and solubilizing aggregated or insoluble proteins during biochemical analysis.

Is Lab Pro Urea ACS water-soluble?

Yes. Lab Pro Urea ACS is highly water-soluble and dissolves readily at room temperature. This property enables easy preparation of concentrated solutions for protein chemistry, analytical assays, and laboratory research without precipitation issues.

What purity level does this urea meet?

This product meets ACS reagent-grade specifications, with an assay range of 99.0–100.5%. It also features very low heavy metal content, making it suitable for sensitive laboratory, analytical, and biochemical applications requiring high chemical purity.

How should Lab Pro Urea ACS be stored and handled?

Urea should be stored under standard laboratory conditions in a tightly sealed container to prevent moisture uptake. Handle using appropriate laboratory safety practices, including gloves and eye protection, to ensure safe and contamination-free use.
