Preparation Guidelines
1
Weighing: NaCl is hygroscopic. Weigh quickly in a dry environment. Tare the container, add the required mass, and close the stock container immediately.
2
Dissolution: Dissolve in distilled or deionised water with stirring at room temperature. NaCl dissolves readily — no heating required for standard concentrations. For saturated solutions (>357 g/L at 20°C), gentle heating may be required.
3
pH Adjustment: NaCl solutions are nearly pH-neutral (pH 6.7–7.3). For buffer preparation, adjust pH after all components are dissolved and before final volume adjustment.
4
Sterilisation: Autoclave NaCl solutions at 121°C for 15 minutes. Alternatively, filter-sterilise through a 0.2 µm membrane filter for heat-sensitive applications.
Storage & Shelf Life
Store at 15–25°C in a tightly closed container. NaCl is hygroscopic — moisture absorption causes caking. Keep dry; use a desiccant in the storage area if humidity is high. Shelf life: indefinite under proper dry storage conditions. Purity unaffected by age if stored correctly.

| 5. Fire Fighting | Not flammable. Non-combustible. Use any extinguishing medium appropriate for surrounding fire. |
| 6. Accidental Release | Sweep or vacuum carefully. Avoid dust generation. Collect in sealed container. Rinse area with water. No significant environmental hazard from minor spills. |
| 7. Handling & Storage | Handle in well-ventilated area. Avoid dust inhalation. Store at 15–25°C, tightly sealed, dry. Keep from strong oxidising agents. Hygroscopic — reseal promptly. |
| 8. Exposure / PPE | Nitrile gloves for prolonged contact. Safety spectacles. P1 dust mask if handling in bulk. OEL: inhalable dust limit (10 mg/m³). |

| 11. Toxicology | Low acute toxicity — LD50 (rat, oral): 3,000 mg/kg. Not carcinogenic, not mutagenic, not a reproductive hazard at normal use concentrations. |
| 12. Ecology | Low acute ecotoxicity. NaCl is a natural component of marine and brackish environments. Large quantities may affect soil salinity and aquatic organisms — avoid bulk disposal to waterways. |
| 13. Disposal | Dilute solutions: dispose to drain with large volumes of water (per local EPA). Solid waste: dispose as non-hazardous solid waste per local EPA regulations. |

Frequently Asked Questions
❓ Lab grade vs food grade — what is the difference?
Laboratory grade NaCl (ASC-8051, ≥99.5%) meets specific analytical purity standards including heavy metals, sulfate, chlorate, and insoluble matter limits not required for food grade. Food grade salt may contain anti-caking agents or iodine. For sensitive laboratory applications — buffer preparation, culture media, molecular biology — always use laboratory grade.
❓ How do I prepare PBS using ASC-8051?
Standard 1× PBS (pH 7.4, per litre): NaCl 8.0 g + KCl 0.2 g + Na₂HPO₄ 1.44 g + KH₂PO₄ 0.24 g. Dissolve in 800 mL distilled water, adjust pH to 7.4 with HCl, then make up to 1 litre. Autoclave 121°C/15 min to sterilise. For 0.9% normal saline: dissolve 9.0 g NaCl per litre of distilled water.
❓ Does NaCl expire?
NaCl is a stable inorganic salt with an indefinite shelf life under proper dry storage conditions. Purity is not affected by age. The expiry date on the label reflects AuSaMicS quality assurance policy. Re-test if the product has been stored in humid conditions or shows significant caking.
❓ Is ASC-8051 suitable for molecular biology applications?
Yes. The high purity (≥99.5%) and low heavy metals specification (≤5 ppm Pb equivalent) make ASC-8051 suitable for most molecular biology applications including PBS preparation, DNA/RNA extraction buffers, hybridisation solutions, and culture media preparation. For ultra-sensitive applications requiring nuclease-free reagents, confirm suitability with your specific protocol requirements.
