12 x 125 ml Polypropylene (PP) wide mouth bottles by United Scientific Supplies

Possible homebrew uses include: Refractometer and pH sample collection, yeast rehydration, yeast washing and slurry storage. Also an easy vessel for making and storing sanitized water.  I use similar containers (mine are larger at 500ml) to collect samples and to aid with yeast rehydration.  Check out Tip 1 on our Tips Page for more info on my process for yeast rehydration.
