Bel-Art Mason Jar 4 L Wide Mouth PP PK2

Bel-Art 4 L Mason Jar Pair

These two wide-mouth polypropylene jars each hold four litres and are supplied with screw-on closures. They are intended for laboratory sampling and general-purpose storage where a clear, cylindrical container is required. The translucent body lets users check contents at a glance without opening the lid.

Behaviour under sustained laboratory use

Polypropylene resists a broad range of common laboratory chemicals and tolerates repeated filling and emptying without cracking. Because the jars are non-sterile and not pre-cleaned, users must apply their own cleaning protocol before first use and between samples. The material is not autoclavable, so heat sterilisation above the polymer's softening point must be avoided.

Build quality and daily handling

The screw-on closure creates a secure seal that reduces spills during transport or when jars are stacked on a bench. Wide mouths simplify pouring, scooping and cleaning with standard brushes. Supplied as a pack of two, the set provides an immediate spare or duplicate for parallel workflows.
