12 x 500 ml Polypropylene (PP) wide mouth bottles by United Scientific SuppliesMore Info
From the product description, check product page for current description, price and availability:
Available in polypropylene (PP) as well as high density polyethylene (HDPE). The PP bottles are rigid, translucent and have excellent contact clarity. These bottles can be autoclaved. The HDPE bottles are not rigid yet have excellent strength.
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 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.\
