cross-linked high-density polyethylene, PPCO base
Tough, stiff, seamless jars resist stress-cracking. Ideal for soaking glassware, washing pipets with corresponding NALGENE rinsers and baskets. Flanged base for added stability. Make excellent large general purpose containers and come with dust covers. The formula shown on the jar's label is effective and lasts longer than standard solutions. Do not mix this solution in the pipet jar. Keep jar on a drainboard, in a sink or in a container large enough to retain jar contents in case of leakage. The 5-gallon heavy-duty cylindrical container (Cat. No. 11100-0005) is recommended for storing the pipet jar, when using this solution.
Caution: Concentrated sulfuric acid will cause pipet jar to fail. When cleaning pipets with a sulfuric acid-dichromate compound, the acid concentration must be 60% or less.
