Casts requiring disinfection are sprayed with a 5.25% sodium hypochlorite solution
and allowed to sit for at least 10 minutes.
The resultant slurry was respectively transferred into sterile labeled 250ml flasks in readiness for preservative treatments with the already prepared 100mls of different sodium chloride solutions: 3%, 6%, 9% and 12%; sodium hypochlorite solutions
: 50ppm, 100ppm, 150ppm and 200ppm; and M.
Based on visual observations, an acceptable degree of surface decolorization can be achieved with a minimum of 10 minutes of bleaching with an aqueous sodium hypochlorite solution
containing 10 to 13 percent available chlorine and 10 minutes of light exposure from a Xenon arc lamp.
When a cup of bleach is diluted in a bath tub full of water, the sodium hypochlorite solution
is weaker than Dalkin's but still effective.
Aqueous sodium hypochlorite solution
(household chlorine bleach) is used to convert formalin solutions, initially to formic acid, then to water and carbon dioxide.
One technique for this pretreatment is immersion in an acidified sodium hypochlorite solution
. The company's chlorinator system can provide this pretreatment process.
The sodium hypochlorite solution
darkens the latent print(s) developed with physical developer, lightens the background, and removes any ninhydrin stains that may still be present on the specimen(s).
Several grades of sodium hypochlorite solution
are readily available to the formulators of cleaning products.
Available systems provide 3 to 2,400 lb per day of chlorine in the form of a dilute sodium hypochlorite solution
produced by the electrolysis of brine.
In current study Cleansing agents were found to be effective in the following order, Sodium hypochlorite solution
, Sodium metaborate and Chlorhexidine gluconate.
