Sodium Hydroxide, Certified

Sodium Hydroxide, Certified:

Sodium Hydroxide (NaOH), also known as caustic soda or lye, is a strong base commonly used in various chemical processes. Certified Sodium Hydroxide refers to a high-quality grade that meets specific standards for purity and consistency, often certified by a governing body or manufacturer to be of known concentration and free from contaminants. Sodium hydroxide is widely used in industrial and laboratory applications, including chemical synthesis, pH adjustment, cleaning, and analytical purposes.

The certified grade of sodium hydroxide ensures high purity and reliability, making it ideal for sensitive reactions and standardized processes in laboratories and industries like pharmaceuticals, chemicals, and food production.
