• Sample preparation solutions
• Washing and rinsing solutions
• Laboratory buffer systems

IMPORTANT NOTE
The suitability of this Extra Pure grade for clinical, pharmaceutical manufacturing, cell culture or other regulated applications should be confirmed against the required compendial or application-specific specification.

SAFETY INFORMATION
Under normal laboratory conditions, sodium chloride is generally considered a low-hazard chemical.

Good laboratory practice should still be followed:
• Avoid generating or inhaling excessive dust.
• Avoid unnecessary contact with eyes.
• Wash hands after handling.
• Use suitable personal protective equipment according to laboratory procedures.
• Refer to the manufacturer’s Safety Data Sheet (SDS) for complete safety information.

GHS CLASSIFICATION
The product label indicates no GHS hazard classification for the supplied material.

STORAGE
• Store in a cool, dry and well-ventilated location.
• Keep the container tightly closed.
• Protect from excessive moisture and contamination.
• Store away from incompatible materials.
• Maintain the manufacturer’s recommended storage conditions.

HANDLING
• Use clean, dry laboratory tools when dispensing.
• Avoid introducing moisture or contaminants into the container.
• Close the container immediately after use.
• Follow good laboratory and chemical hygiene practices.

QUALITY DOCUMENTATION
Where required, users should consult:
• Certificate of Analysis (COA)
