I make 5kg of 100ppm hypochlorite solution by mixing 10g bleach with 4990g water. After sanitization i recycle and store the remaining solution and use it next time and next time. When the quantity left is not enough, i make another 5kg batch and mix it with this recycled one and use it.
My questions are
1. Is there any time limit or recycling limit for this 100ppm hypochlorite solution like for how many days i can store it or how many time i can recycle it after sanitization of equipments?
2. Is it ok if i mix new batch with recycled one of 100ppm hypochlorite solution and use it?
@PhilGeis i am spraying again and again everything except the pipes with hypochlorite for 20 minutes. The problem in that with small sample size was waiting 20 minutes every day for 100-500g sample that would be prepared in 5 minutes was frustrating. Also since you said don’t store the 100ppm hypochlorite solution, preparing small amount each time was also a pain.
I will try spraying small equipments for sample with alcohol.
can you explain what is this vapor pressure? What causes it? And how to prevent it?
I will say during sanitization every equipment is open and not closed the way that gas can’t come out of it.
