All plastic is not the same - our boxes are injection molded meaning they are engineered for strength and durability. The plastic we use is UV-stabilized, meaning no warping, cracking, or degradation from sun exposure. This has been independently tested by ExcelPlas to withstand 25+ years exposure to high UV, so you have peace of mind guaranteed.

We have tested our core boxes to handle freezing conditions to -50degC/ -58degF and exposure to high UV while still protecting your valuable core. They are currently being used in some of the harshest climates, including Canada and Mongolia.

When you are pulling the box along logging tables or lifting them onto vehicles, getting a decent grip on a fully loaded box is important. Then the flat bottom design ensures smooth movement on roller racking and ball transfer tables in any direction or angle, without disturbing the core samples in the box.

The Discoverer S5 Core Box Lid is made from a single-piece molded plastic with integrated clips that hold it firmly on the box. The design allows every core box to be sealed with its own individual lid, and then stacked on top of each other stably.
