Laboratory-grade dilution bottles in autoclavable glass or plastic. Products are suitable for pharmaceutical, water, dairy product, or food sample testing. Products include Thermo Scientific™ Nalgene™ Polysulfone Dilution Bottles with Closure, which are designed to resist bases, and weak acids. Available with either a narrow or wide mouth for liquid or solid samples, these bottles are also useful for general storage and tissue culture work. Dilution bottles come with screw-on or flip-top lids, and some offer a graduated option to provide more precise sample dilution measuring.
