Description
Ultra-pure distilled water with 0.9% benzyl alcohol as a preservative. Formulated as a laboratory-grade diluent for research applications.
A single 20 mL vial gives you the same volume as two 10 mL vials with one seal to break and one batch to record, and at $27 it's $7 less than two 10 mL singles at $17 each.
When 20 mL makes sense
Built for high volume laboratory work. One 20 mL vial replaces six 3 mL vials, which means fewer septum punctures, fewer opened containers, and one batch reference across a full workflow.
