This RS PRO plastic narrow neck round wash bottle is commonly used as a wash bottle or a piece of laboratory equipment for dispensing liquid. It's also suitable for household use. The LDPE (low-density polyethylene) material is flexible enough to make the bottle easy to squeeze yet durable enough to resist physical impact, temperature changes and chemicals. This type of material is environmentally friendly as it's widely recyclable. For greater flexibility when dispensing liquids, it has a pivoting closure with a nozzle that retracts into the cap to seal it. This bottle is particularly useful for dispensing gels in laboratory or domestic applications.
