Thermo Scientific Nalgene Large-Capacity Round Bottles are available in three different material/opening configurations:
Wide-Mouth High-Density Polyethylene Bottles are excellent for dry chemicals or water sampling. Use in freezer to -100°C.
Wide-Mouth Polypropylene Bottles are specifically designed for applications requiring autoclaving of large volumes. Note: bottles are not leakproof.
Narrow-Mouth Polypropylene Bottles can be used to store chemicals or distilled water. Bottles EF2231E and EF2231F include a shoulder loop where an ID tag can be attached.
All bottles include a polypropylene screw closure. Polypropylene bottles are autoclavable: before autoclaving, just set polypropylene screw closure (included) on top of bottle mouth without engaging threads.
Polyethylene or polypropylene; wide or narrow mouth
