disposable BOD bottle
« on: 27/02/2015 15:34:40 »
I am in the midst of developing a plastic BOD bottle for the BOD5 analysis.
The material I am thinking of using is PET as it is cheap and environmentally friendly and I am thinking of using polypropylene for the stopper.
Other than oxygen ingress through the stopper and oxygen permeation from PET, is there anything else I have not considered?
As far as I know, there is only one company out there that makes this, and for one reason or another, not many people use them. I believe the market is out there.....
