A 300mm × 300mm platten in aluminium. Recommended for general compression testing where the sample has a large surface area. Point loading should be avoided as the aluminium may be damaged.

Stabilising feet can be fitted if required at a small extra charge.

It is possible to develope large bending moments on the machine loadcell using plattens of this size if the sample is not centralised. Guidance marks are machined into the surface of the lower platten to assist sample location.
