Wash bottles are constructed from laboratory-grade low-density polyethylene (LDPE), ensuring low levels of leachables and broad chemical compatibility with various laboratory reagents. Designed for reliable, sputter-free dispensing, these bottles feature a soft, ergonomic squeeze that allows controlled and precise fluid delivery. They are ideal for rinsing laboratory glassware, bringing volumetric flasks to final volume, and other accurate solution dispensing tasks. The dispensing nozzle is integrally molded with the cap to prevent detachment during use. For increased flow, the tip can be trimmed as needed.
