Product Overview
This HPLC-grade water is engineered for ultra-high purity, meeting stringent laboratory requirements where trace contaminants can compromise results. With a total organic carbon (TOC) level below 0.1 ppb, it eliminates interference in sensitive analytical techniques like HPLC, LC-MS, and UV-Vis spectroscopy. The water undergoes 0.22 µm sterile filtration to remove particulate matter and microbial contaminants, ensuring reliability in cell culture and molecular biology applications. Its low conductivity (<1 µS/cm) and neutral pH (6.8–7.2) prevent baseline drift in chromatographic separations, while the absence of endotoxins (<0.03 EU/mL) makes it suitable for biopharmaceutical and life science research. Packaged in Type I borosilicate glass bottles with PTFE-lined caps, it resists leaching and contamination during storage. The product is tested for heavy metals (Pb, As, Hg <1 ppb) and residual solvents, providing consistent batch-to-batch performance for critical lab workflows.
FAQs
1. What is the shelf life of HPLC-grade water after opening?
Once opened, the shelf life is approximately 3 months if stored in its original container at room temperature (15–25°C) and protected from light. For extended stability, aliquot into sterile containers and refrigerate at 2–8°C.
2. Can this water be used for GC-MS or ICP-MS applications?
While it meets purity standards for most chromatographic techniques, GC-MS and ICP-MS require additional testing for volatile organics and inorganic contaminants. For these applications, opt for dedicated GC-MS or trace metal-grade water to avoid matrix effects.
3. Is this water compatible with plastic labware?
The water is stable in polypropylene (PP), polyethylene (PE), and PTFE containers. Avoid storing in PVC or polystyrene, as these may leach plasticizers or additives that could contaminate the sample.
4. How does this compare to Milli-Q or Type I reagent water?
This HPLC-grade water matches the purity of Type I reagent water (18.2 MΩ·cm resistivity) but is pre-packaged for convenience. Unlike Milli-Q systems, it eliminates the need for in-house purification, reducing maintenance and validation costs.
5. What precautions should be taken during handling to avoid contamination?
Use powder-free nitrile gloves and sterile pipettes to prevent keratin or microbial introduction. Work in a laminar flow hood if possible, and avoid exposing the bottle to direct sunlight or temperature fluctuations.
