Deionized water with electrical resistance of 18.3 megaohm-cm* and total organic compound (TOC) less than 10 ppb** |
For analytical works which require high accuracy, e.g. HPLC, FPLC, IC, GC,GC-MS, TOC, AAS, ICP/MS, AAA, Bod |
Grade IIIB: Bioresearch Grade (Deionized, free organic, & pyrogent free water) |
Deionized water with electrical resistance of 18.3 megaohm-cm and total organic compound (TOC) less than 10 ppb. Pyrogen (bacterial endotoxins) contamination is less than 0.005EU/ml. |
Cell and tissue culture DNA and IVF research, Monoclonal antibody, other life science application |
*measured at 25°C
**TOC and metal ion can rapidly increase due to improper handle of the purified water, e.g. storage in plastic or glass containers.
