Reduce the risk of contamination when dispensing sterile water or reagents by using autoclavable Thermo Scientific™ Nalgene™ PPCO Wash Bottles. Made from high-quality, laboratory-grade, plastic materials for dependably low leachables and extractables. These squeeze bottles are flexible, contact-clear, and designed to dispense through the top with a closure and stem molded in one piece for reliable service. Bent stem dispensing tube retains its bend after autoclaving but bend angle can be modified by hand while warm if desired. The tight fit of the draw tube and closure prevents separation when squeezing bottle.
