Liqui-Nox® Critical Cleaning Liquid Detergent

Other applications outside the laboratory


Spanish




Used to Clean:
Healthcare instruments, laboratory ware, vacuum equipment, tissue culture ware, personal protective equipment, sampling apparatus, catheters, tubing, disk drives, clean rooms, EEG patient prep, optical parts, electronic components, pharmaceutical apparatus, cosmetics manufacturing equipment, metal castings, forgings and stampings, industrial parts, pipes, tanks and reactors. Authorized by USDA for use in federally inspected meat and poultry plants. Passes inhibitory residue test for water analysis. Used for phosphate sensitive analysis ware.

Used to Remove:
Soil, grit, grime, slime, grease, oils, blood, tissue, particulates, deposits, chemical and solvents.

Surfaces Cleaned:
Corrosion inhibited formulation recommended for glass, metal, stainless steel, porcelain, ceramic, plastic, cement and fiberglass. Can be used on soft metals such as copper, aluminum, zinc and magnesium if rinsed promptly. Used for art restoration. Corrosion testing may be advisable.

Leak detection:
Liqui-Nox seems to be the ultimate leak detection medium when searching for leaks on just about any system where there is a pressure differential. Whether it be for a slow leak on an automobile tire, a pressure hose, or even a vacuum system o ring seal.

Cleaning Method:
Soak, brush, sponge, cloth, ultrasonic, flow through clean-in-place.

Special caution: This product will foam, it is not for spray or machine use.

Chemical Description:
LIQUI-NOX consists primarily of a homogeneous blend of sodium linear alkylaryl sulfonate, sodium xylene sulfonate, alkanolamide, and ethoxylated alcohol. LIQUI-NOX is anionic in nature.

Cleaning Validation Methods:
Test a parameter of rinse water before and after rinsing the cleaned surface. No significant change in the parameter indicates no detectable residue. Parameters measured include: pH, conductivity, resistance, spectrographic methods, sodium concentration, phosphorus concentration, anionic surfactant concentration using inexpensive detergent water testing kits, surface tension, and surface analysis.
