Cell Culture Suited Water
PurMa™ Cell Culture Suited Water is suitable for day-to-day culture experiments. Moreover, we deplete Ca+2 and Mg +2 and vigorously evaluate all our waters for mycoplasma and endotoxins.
Description
Background
PurMa™ Cell Culture Suited Water is suitable for day-to-day culture experiments. Moreover, it has been depleted of Ca+2 and Mg+2.We vigorously evaluate all our waters for mycoplasma and endotoxins.
Special Features
- Purified by Deionization (DI) followed Reverse Osmosis process (18.2 ΩM/cm2).
- Additionally, the trace of heavy metals including Ca+2 and Mg +2 have been depleted. This is, however, performed using ion exchange chromatography resins.
- We also sterilize cell culture grade water by 0.2 µm filters.
- Lastly, we pack it under N2.
