Material Type

Lab bottles commonly have a variety of components, such as bodies, caps and closures, seals, straws, and droppers that can be made of various materials.

• Borosilicate glass has high chemical resistance, resists thermal expansion and shock, is heat-resistant, and is commonly selected for many pharmaceutical applications. It is the most common glass lab bottle type. 
• Glass is an inert brittle solid, heat-resistant, and typically transparent. It does not allow transmission of gases or vapors, and has solution-compatibility. Lab bottles come in a variety of glass types, such as borosilicate and soda-lime. Colored or tinted glass, such as amber, cobalt blue, or red, has ultraviolet (UV) resistance.
• Low-density polyethylene (LDPE) is a thermoplastic that is lightweight, flexible, durable, and impact resistant. LDPE lab bottles are squeezable, and retract back to their original shape. It is more opaque, have less chemical or solvent resistance, and more resistant to stress cracking than high-density polyethylene (HDPE). LDPE bottles are commonly used in dropper and wash bottle applications.
