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)
- High-density polyethylene
(HDPE) is a thermoplastic resistant to low temperatures and
impact, and does not absorb moisture. It is more transparent than
low-density polyethylene (LDPE). It is used in many pharmaceutical,
water-based chemicals, high speed-filling, and some food product
- 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.
Stainless steel is rigid, shock-resistant, and can
withstand temperature variations.
