Rectangular Jar, Plastic

Quick answer: A rectangular plastic jar is a general-purpose laboratory storage container with a space-efficient rectangular footprint, used for storing dry samples, small specimens and reagents on shelves and in cupboards.

Unlike round jars, a rectangular jar packs closely against other rectangular containers, making better use of limited shelf and cupboard space in busy teaching and research laboratories. Being moulded in plastic rather than glass, it is also naturally more resistant to breakage from accidental knocks, which suits everyday handling in student laboratories and stockrooms.

These jars are typically used with a fitted lid, allowing dry materials, small specimens or compatible reagents to be stored securely between uses while keeping dust and contamination out.
