Autofil® ergonomic bottles feature rounded, sloped shoulders with generous finger holds for easy transport. Wide bases aid stability and create a low center of gravity. The unique SECUREgrasp™ cap has no-slip edges for a safer grip and a large flat surface for convenient labeling.

Each bottle has large raised graduations on the front and back. Additional head space allows dilutions of up to 15%. Autofil bottles are available in three low extractable plastics. All components meet USP Class VI and FDA requirements and are non-cytotoxic. Sterile bottles are pyrogen free.

Polystyrene (PS) is recommended for most cell culture aqueous solutions and is stable to 80° C. PS is also generally suitable for weak acids, bases, or dilute alcohol. PS bottles have white caps and are not autoclavable.
