I need to make a custom size bottle to store developer (modified Ansco 17M). I am going to make it out of several components, made of white PVC and black ABS plastic. I will be joining the components with the approved cement for this type of application. I have previously made, and use, processing tanks made of white PVC, and they work just fine. Has anybody ever done this? Are there any potential problems with using ABS for storage? PVC should be okay, as I have never had any problems with this material, and most modern processing equipment has gray PVC tanks and fluid lines. Any input on this subject would be welcome.
