Liofilchem® Lactic Acid 10% Solution is a sterile additive used to adjust the pH of microbiological culture media. It is particularly suited for media such as Malt Extract Agar and Potato Dextrose Agar, where pH reduction enhances the selective growth of fungi and yeasts. Each 10 mL vial contains a precise amount of lactic acid (1.0 g in distilled water), ensuring consistency and reproducibility in laboratory workflows.
One vial is sufficient to treat 500 mL of culture medium. The solution must be added after autoclaving and cooling the medium to 45–50 °C to preserve sterility and functionality.
Key Features
- Precise pH Adjustment – Designed to lower the pH of culture media for selective microbial growth.
- Sterile Ready-to-Use Solution – Supplied in 10 mL vials for direct addition to culture media.
- High Quality – Manufactured to ISO-certified standards, ensuring consistency and reliability.
- Compatible Media – Recommended for use with Malt Extract Agar and Potato Dextrose Agar.
- Proven Performance – Validated with reference strains such as Candida albicans, Saccharomyces cerevisiae, and Aspergillus brasiliensis.
Applications
- Adjustment of culture media pH for fungal and yeast cultivation.
- Use in clinical microbiology, food testing, and industrial microbiology.
- Preparation of selective and differential culture media.
- Standardized workflows for mycology and environmental monitoring.
