Type I Deionized Water Ultrapure Analytical Grade (1 Gallon) - ASTM/ACS Certified

Worked great for what I needed it for.

Research shows that using Deionize water over anything else for PCB copper foil electroplating process is a must to have when repairing damage copper foil on any electronics consumer products such as graphics cards, motherboards, video game consoles and much more. This is a must to have for any DIY pcb repair person in their tool-kit. you can also use this to re-plate regular aluminum foil on compact discs store purchase PS1 games using the same process to prevent data loss of any kinds before data is loss or the original foil deteriorates. This stops and prevents such issues from occurring during this process! Water quality is ultrapure meaning its good for anything but drinking it is not safe at all. If you read up online for the PCB electroplating process it mentions this water is recommended! :)

Purchased for flushing after cleaning my water loop in my gaming PC.

Great for urgent reagent prep needs. Worked perfectly for isotope analysis.

We keep this handy in a spray bottle and it's great for many cleaning chores and even simple first aid. And it's the simple solution for windows that just never seem to come clean - wash them first with plain tap water and rinse with this. No window cleaning chemicals needed and they come out smudge and film free. Same with car windows. Glad we learned about it.

I needed DI water for some field blanks & couldn’t find it anywhere local or from a reputable online supplier in the quick timeframe I had for a high profile project. I was super nervous to get back all the test results but the blank came back all ND! So for anyone who may need DI water for groundwater and stormwater sampling reasons, I can confirm this gallon did not screw me over.

We got this stuff tested for our lab. Seems clean enough: Chloride (mg/kg) 0.37 Nitrate (mg/kg) 0.08 Phosphate (mg/kg) 0 Sulfate (mg/kg) 0.048 Ammonium (mg/kg) 0.03 Evaporation Residue (mg/kg) <0.01 Total Carbon (mg/kg) <1 Aluminum (mg/L) 0.001 Tin (mg/L) <0.001 Here's how it compares with regular Glacier Mist distilled water from the grocery store: Chloride (mg/kg) 0.432 Nitrate (mg/kg) 0.136 Phosphate (mg/kg) 0.15 Sulfate (mg/kg) 0.496 Ammonium (mg/kg) 0.351 Evaporation Residue (mg/kg) <0.01 Total Carbon (mg/kg) <1 Aluminum (mg/L) <0.001 Tin (mg/L) <0.001

I purchased this water for a chemistry lab to use in a chemical reaction that is sensitive to the presence of ions. It worked.

Item received in good condition and fast delivery.
