cabinet where the Ebeam Lab resist are stored.

since last year was also stocked into the left hand

No volume of these material is to leave the lab in liquid form,
nor shall personal supplies of this material are to be taken,
without my express permission.

of these materials after coating on the headway spinner.
Please be careful and frugal with these very expensive engineering
materials and strive to minimize your volumes of usage.
