The murkiness is fine dust from the molecular sieve. It settles out
after a few to several hours. You have to remember to never shake the
bottle or pour from it. Use a transfer pipette to get EtOH out of the
Put the sieve in dialysis tubing. This will contain the dust, but do
as effect a job of keeping the EtOH dry.
Sieve works very well. I've used it for years.
>Dear Histonet Community,

>Does this go away completely -- with longer sitting of the ethanol??? Or

>getting back into the EtOh?
>Thanks so much.
