Nalgene™ Polycarbonate Baffled Culture Flasks

Polycarbonate is break-resistant and clear; easy to read graduations help identify liquid level with ease. Bottom baffles provide increased mixing, aeration, and gas exchange. Flasks are excellent for a variety of lab procedures, including fermentation, cell culture grown and harvesting, and generic engineering procedures. 500 and 100mL sizes accept either standard 38mm stainless-steel or plastic closures. Flasks are autoclavable. Note: Repeated autoclaving may result in some loss of mechanical strength.  Wash and rinse well before autoclaving.
