It is important that the bottom of the jar is very flat, The sample jars must be stable, i.e. they must not wobble on the measuring bench of the penetrometer.

Otherwise, this would increase the risk of measurement errors. Due to lateral drift of the penetrator and the plunger. It is advisable to throw away sample jars which have been deformed when dropped etc.

The diameter of the sample jars must be adequately large in order to avoid the measurement result being influenced by wall effects,

in particular, when working with test cones, to prevent the cones contacting the rim of the jar.

As a general guideline, the diameter of the sample jar should be approximately three times the penetration diameter of the penetrator.

The dimensions of the sample jars have been selected in accordance with requirements of international mineral oil standards and are characterized by uniform dimensional accuracy and excellent stability.
