Polypropylene carboys are made from a USP Class VI, FDA Grade, autoclavable material. The recommended autoclaving cycle is: 15 PSI for 20 minutes at 121° C

These carboys are designed to provide users with a highly versatile container that maximizes storage efficiency and ease of use. The distinctive rectangular shape saves valuable bench space. Larger handles on top of the container and molded grips in the base provide a full, secure grip to make lifting, handling and pouring easy. The optional wide neck allows the user to reach inside the carboy for easier cleaning. Carboy material and volume are clearly imprinted on the outside of the bottle as well as large, easy to read, metric graduation marks which are certified to ±5% accuracy.
