FAQs

What is this product and how is it used?

This is a laboratory-grade sodium chloride standard at 1.00% (w/w) concentration. It’s supplied in a 500 mL natural poly bottle, ACS grade with an assay tolerance of ±0.01%. Labs use it for calibrations, quality checks, and analytical procedures requiring a known NaCl standard.

What are the key specifications and shelf-life?

The solution carries CAS numbers 7732-18-5 (water) and 7647-14-5 (NaCl). The manufacturer lists a shelf life of 24 months when stored properly, and a typical tolerance of 0.99-1.01% (w/w).

In what applications should I use this standard?

Use it for laboratory testing, research, manufacturing workflows, or whenever a consistent, traceable NaCl concentration is required—for example in calibration of conductivity instruments, reagent prep, or ion analysis. The clear, stable standard helps maintain analytical integrity.

What storage and handling considerations apply?

Store the bottle sealed, in a cool, dry location, away from strong light or contamination. Use only within the specified shelf‐life. Avoid introducing contaminants (e.g., dust or other chemicals) into the solution, as this can alter the concentration. Refer to SDS for hazard and safe‐use information.

Is this product certified or traceable?

Yes, Ricca offers full documentation, Certificates of Analysis (CoAs) and SDS sheets for this product, and emphasizes tight manufacturing tolerances and lot‐to‐lot consistency.
