This bulk pack of 2000 narrow-mouth HDPE reagent bottles has a 4mL capacity per bottle with polypropylene caps. The translucent HDPE construction provides visual content monitoring and excellent chemical resistance for storing reagents, solutions, and samples. The bottles are non-sterile, leak-proof, and rated for temperatures from -100°C to 120°C. The narrow-mouth design provides controlled dispensing of small liquid volumes. The 2000-unit bulk format is designed for large-scale laboratory or industrial applications requiring high-volume small-format storage.
