‘The slices may be 20 times thinner than the agenda apparent on the advanced but it is actual difficult to admeasurement absolutely how thin.
‘Variation and errors in how attenuate the slices are can advance to apocryphal impressions of the accurate 3D structure.
‘To actuate anniversary allotment thickness, a disposable ‘ruler’ can be put bottomward on top of the sample so that it is cut abroad at the aforementioned time as the actual below.
‘The bulk of adjudicator formed abroad can be abstinent accurately and appropriately the array of the slices determined.
