DNase/RNase-Free Distilled Water, 500 mL

CCM-RG-0020 is DNase/RNase-free distilled water intended for laboratories that require a controlled water source for preparation, dilution, rinsing, and reconstitution steps in cell culture and molecular biology support workflows. It is classified as animal origin-free, making it suitable for procurement programs that restrict animal-derived raw materials in research and process development environments. Supplied in a 500 mL format, it is convenient for shared laboratory benches, media preparation areas, and small-batch reagent production.

The specification profile supports routine use in controlled cell culture operations: pH 5.0–7.0, osmolality 0–5 mOsmol/kg, endotoxin not more than 5 EU/mL, and a 12-month shelf life when stored as directed. These parameters are relevant when water is used in contact with sensitive reagents, serum-free supplements, buffers, and cultureware. For related products used in upstream workflows, see our cell culture reagents category or contact CellCultureMedia for sourcing support.

• Preparation of cell culture reagent dilutions where DNase/RNase-free water is required by the protocol.
• Reconstitution of powdered or concentrated laboratory reagents used in research cell culture workflows.
• Buffer and rinse solution preparation for non-final formulation process development tasks.
• Support for molecular biology steps adjacent to cell culture, including RNA- or DNA-sensitive sample handling.
• General laboratory water supply for low-osmolality, animal origin-free reagent preparation.
• Small-batch process engineering studies where a documented water input is preferred over unqualified in-house water.

Store CCM-RG-0020 at 2–30 °C protected from light. Keep the container tightly closed when not in use and handle with clean laboratory technique to maintain nuclease-free performance after opening. The product ships at room temperature, which simplifies receiving and inventory routing for multi-site procurement teams. Do not use beyond the assigned 12-month shelf life or if the container integrity is compromised. As with all shared laboratory reagents, assign the bottle to a defined work area when possible to reduce cross-use handling risk.

CellCultureMedia supplies CCM-RG-0020 for research, cell culture, and bioprocessing support applications under ISO-aligned supplier quality practices. Lot-specific documentation can confirm applicable release parameters such as pH, osmolality, endotoxin specification, and nuclease-free status. Sterility-related information should be verified on the lot documentation when required for a specific workflow. A Certificate of Analysis is available on request through our quality documentation team.
