Isopropyl 70% vs. Isopropyl 91%

hey folks,
I just used isopropyl 70% rubbing alcohol on my cotton that I cleaned down the needle syringe to inoculate my grain jars.
I have read that it is suggested to use isopropyl 91%
Should I be worried? I checked it out after innoculating, I should have known, I bought it at a cheap ass dollar store....

70% will work fine, dollar store iso is all i use also. It is believed that 70% actually works BETTER then 90% iso.. as it takes longer for it to evaperate, so you get longer steralizing time, even tho it is weaker

91% is more effective... 70% will work just fine though.

Best buy the 91% if it is not much more expensive. You can then dilute it yourself if you want 70% slow evaporating stuff. I like the fact it evaporates fast, for my hands.

I've been using 70% forever, with great results. Works for me.

70% is more effective at killing organisms than 91%, but in my opinion, syringe needles should be flame sterilized. Alcohol on a cotton wad will do nothing for contaminants on the inside of the needle. RR

i back roger on this. see when a cell such as a mold spore comes in contact with the alcohol, it rejects it because cells on this planet need water to survive and grow. when the alcohol is dilluted with more water the cell is more accepting of the liquid. it's kinda like a trojan horse.

yah, but 70% iso is more then enough to kill off any possible contams and is a great preventative measure in between your innoculations.
My sterile procedure always involve cleaning my work area, hands, wrists, and up to the elbows with alcohol. Works for me, both strengths provide great results as well I like the 91% for my hands because it evaps quicker./
