Lightweight economy version of the original Nalgene bottle. Suitable for short-term general purpose laboratory and field applications such as collecting samples and containing working solutions like buffers, bench reagents and chemical aliquots. Thinner-walled and more flexible than the Nalgene Lab Quality Bottle, but still guaranteed leakproof. Wide mouth is easy to fill with dry materials or liquids. Translucent. Excellent chemical resistance to most acids, bases and alcohols. Note: The Nalgene Lab Quality Bottle (Cat. No. 2104) is recommended for hazardous and critical material containment.
