L(+)-Lactic Acid, 20 wt.% Solution in Water – Laboratory Acidulant & pH Adjuster (BZ524)

Price range: $22.00 through $69.00

L(+)-Lactic Acid, 20 wt.% Solution in Water BZ524

Product Code: BZ524
Manufacturer: Biochemazone
Available Pack Sizes: 100 mL, 200 mL, 500 mL, 1 L
Custom Bulk Quantities Available

Product Overview

Biochemazone L(+)-Lactic Acid, 20 wt.% Solution BZ524 is a ready-diluted aqueous solution of the naturally occurring L(+) enantiomer of lactic acid (2-hydroxypropanoic acid) at 20% by weight – roughly 2.3 mol/L. It saves handling concentrated 85–90% lactic acid, which is viscous and corrosive.

Lactic acid is a weak organic acid (pKa about 3.9) found naturally in the body and in fermented foods. In the lab it is used for pH adjustment, acidifying culture media, preparing artificial sweat, urine and other simulated fluids, chiral and fermentation research, biopolymer (PLA) studies, and cosmetic, food and antimicrobial research.

Each batch is prepared with ISO 3696 compliant high-purity water under Biochemazone’s ISO 9001 / GMP quality system.

Frequently asked questions

What is the molarity of 20 wt.% lactic acid?

About 2.3 mol/L, based on a density of about 1.05 g/mL.

Why buy 20% instead of 85–90% lactic acid?

Concentrated lactic acid is viscous and corrosive. The 20% solution is easier to measure and dilute accurately.

Is it safe to handle?

It is an acid that irritates skin and eyes. Wear gloves and eye protection and follow the SDS.

Can I use it to make artificial sweat?

Yes. Lactic acid is a common component of artificial sweat and other simulated body fluids. Dilute according to the method you follow.

How should it be stored?

Store at 2–30 °C, tightly closed. Unopened bottles have a 1-year shelf life and ship at room temperature.
