What makes Thermo Scientific™ Nalgene™ bottles better than other bottles?

Nalgene bottles have many features which set them apart from the rest. Here are a few highlights of each bottle:

1. The closure walls are heavy-duty, uniform, and generally thicker than the competition, making them resistant to splitting or puncturing.
2. The closure is one-piece and linerless, setting the foundation for a leakproof system.
3. An inner ring seal is molded-in and fits tightly against the beveled inner edge (chamfer) of the bottleneck, guaranteeing a leakproof system.
4. The cap threads are continuous, straight-shouldered semi-buttress threads, not low-quality round threads.
5. Most Nalgene bottles feature a shrink ring at the neck that is molded so that the inside surface is smooth, minimizing content entrapment.
6. The bottom has curved inner corners for easy cleaning and a stable base with permanent molded-in resin code and volume.
7. Nalgene bottles and carboys do not contain extenders or plasticizers such as phthalates (except for the PVC), which eliminates a source of sampling contamination.
8. Unlike a lot of plastic bottles, most Nalgene bottles up to 4 liters are injection blow-molded, which allows for more precise molding of the neck area and chamfer and more uniform wall thickness. Injection blow-molded bottles feature a smoother, more stable bottom with less molded-in stress for greater product reliability. Furthermore, there are no pinch-offs to cause creases or splits which could harbor contaminants.
