United States Biological Corporation NP40 SUBSTITUTE 100ML
Manufacturer: United States Biological Corporation N3500100ML
Nonidet-P40 is an anhydrous liquid nonionic surface- active agent produced by the reaction of octyl phenol with 8.5-9.5 moles of ethylene oxide. Nonidet-P40 (NP-40) is a nonionic surfactant used in the isolation of membrane complexes. This product has been reformulated to be eco-friendly. The only observable differences are that the viscosity and handling characteristics are somewhat modified. Due to its nonionic structure, this product is compatible with anionic surfactants and is stable in the presence of acids, bases, and salts. It should not be mixed with concentrated oxidizing or reducing agents since the mixture of these compounds with organic compounds could form a potentially explosive mixture. Nonidet-P40 is an effective emulsifier for solvents such as xylene. General Specifications: Appearance: Colorless to pale yellow, clear, viscous liquid pH (1% aqueous): 5-7 Water: 0.50% Specific Gravity (25C): 1.065 Viscosity (cP, 25C): ~246 Surface Tension (0.1% aqueous, 25C): ~30
