UFC BIO Sodium Hydroxide (NaOH) Solution is a sterile, ready-to-use alkaline reagent for pH adjustment, acid neutralization and reagent preparation.
Choose 0.1N, 0.5N or 1.0N in 500 mL or 1 L bottles. Each concentration is made from USP/NF-grade sodium hydroxide in USP-grade 18.2 MΩ·cm deionized water and sterile filtered through a 0.20 µm membrane. Every lot is released against its specification for assay, pH, conductivity, density and USP ⟨71⟩ sterility.
Safety Data Sheet (SDS) and lot-specific Certificate of Analysis (COA) available.

Product Highlights
- Sterile, with a USP ⟨71⟩ sterility release specification; filtered through a 0.20 µm membrane.
- Assay, pH, conductivity and density tested against a defined specification for each concentration.
- Made from USP/NF-grade sodium hydroxide in USP-grade 18.2 MΩ·cm deionized water.
- Non-animal, non-human material origin.
- Product of USA.
Common Applications
- pH adjustment during reagent and process-solution preparation
- Acid neutralization in compatible laboratory and manufacturing workflows
- Preparation of alkaline reagents for biotechnology research and process development
- Acid–base titration where the analytical method specifies this concentration
Qualify the reagent for your process, equipment and product requirements. For quantitative titration, standardize before use and re-standardize as your analytical method requires.
Storage and Handling
- Store at 4–25 °C in the original container, tightly closed.
- Sodium hydroxide absorbs carbon dioxide from the air, which can change its normality. Close the bottle promptly after use.
- Follow the expiration date printed on the label, and check suitability after opening according to your laboratory's procedures.
For laboratory, research and further manufacturing use only.
Frequently Asked Questions
Are normality and molarity the same for sodium hydroxide?
Yes, for acid–base neutralization. Each mole of sodium hydroxide provides one equivalent of hydroxide, so 0.1M is 0.1N, 0.5M is 0.5N and 1.0M is 1.0N.
Is this a pH calibration buffer?
No. It is an alkaline reagent. Use a certified calibration buffer to calibrate a pH meter.
Why do 0.5N and 1.0N ship differently from 0.1N?
0.5N and 1.0N are shipped as Dangerous Goods (UN1824, Class 8), so they ship by ground only within the contiguous US and do not qualify for free shipping or returns. See the Shipping & Returns tab.
How do I get the Certificate of Analysis?
Enter the Lot/Batch Number printed on the bottle in the COA search on the Documents tab.
Are bulk quantities available?
Yes. Contact info@ufcbio.com for package options, bulk pricing and lead times.

Shipping depends on concentration
0.5N and 1.0N are classified as Dangerous Goods (UN1824, Class 8, corrosive) and require special handling. 0.1N ships as a standard (non-hazardous) item.
0.1N: Shipping and returns
Free standard ground shipping when your order includes $50 or more of UFC BIO products, shipped within the contiguous US (lower 48 states).
30-day returns within the contiguous US. Once we receive and inspect your return, we’ll issue a full refund within 3–5 business days. Returns are not accepted more than 30 days after delivery unless an extension is approved.
Orders shipping outside the contiguous US (including Canada) do not qualify for free shipping. Shipping costs are determined at checkout. If a shipping option isn’t available, please contact us at info@ufcbio.com.
0.5N and 1.0N: Dangerous Goods
Ships by ground only within the contiguous US (lower 48 states). Dangerous Goods do not qualify for free shipping; shipping charges are shown at checkout.
Cannot be shipped to Alaska, Hawaii, Puerto Rico, or outside the United States.
Hazardous materials are non-returnable. If your order arrives damaged, defective, or incorrect, please contact us promptly at info@ufcbio.com so we can resolve it.
