Description
Ultra-Pure Nuclease Free Water (Non-DEPC Treated)
Background
PurMa™ Ultra-Pure Nuclease Free Water (Non-DEPC Treated) is specialized for highly sophisticated molecular biology studies. Moreover, This water possesses the highest standards for molecular biology studies by removing all contaminants such as:
- Organic and non-organic compounds.
- Dissolved and particulate matters with any sizes.
- Volatile and non-volatile
- Reactive, and inert
- Hydrophilic and hydrophobic
- Dissolved gases.
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 using Ion exchange chromatography resins.
- Moreover, it is Double – Distilled.
- Sterilized by 0.1 µm filters.
- And lastly, Packed under N2
Important Note: Do NOT expose this water to open air for a long time as it absorbs traces of various ions including bicarbonate.
PurMa™ Non DEPC Treated Ultra-Pure Nuclease Free Water Suitable for high accuracy molecular biology studies, as well as analytical analysis applications such as:
- It Definitely the best choice for mRNA & Total RNA Isolation.
- Mass spectrometry certainly performs the best with this quality of water.
- Electrophoresis, cloning, PCR, RNA, and DNA isolation.
- Especially, chromosome analysis or karyotyping as they need high quality water.
- Also, northern and southern blotting.
- Evaluated for proteases.
- Evaluated for phosphatases.
