We introduce the RS PRO series of LDPE wash bottles, designed for use in laboratories for rinsing laboratory equipment such as test tubes, containers, and bottles. They are robust yet lightweight and compressible, allowing liquids to be easily dispensed through the nozzle caps, enabling continuous and precise distribution while preventing unwanted drips, especially when handling hazardous liquids. The high-quality LDPE wash bottle ensures ultimate durability and safe dispensing of liquids, making it highly versatile for a range of applications where safe cleaning is required. Thanks to the wide neck, the wash bottle allows for easy, spill-free filling, and the precise tip provides accurate control when dispensing liquid, thus preventing spills. The PP cap creates a secure, leak-proof seal to prevent accidental spills or leaks while maintaining its shape during use. Wash bottles are commonly used in laboratories for sterilizing and rinsing laboratory equipment such as cups and test tubes. They can be filled with a variety of cleaning liquids and detergents such as acetone, distilled water, ethanol, and more. They are frequently utilized in fields such as medical technology, laboratories, research, and education.
