In order to make dry ice, the requirement would be to have a pure Carbon dioxide source, this can be super cooled in the freezer to -78degrees centigrade, else instead of fire extinguisher you require another source of liquefied CO2 to make dry ice

Where does UK import tomatoes from?

Why you want to make dry ice when you can buy it from the market at cheaper prices :)

the biggest challenge till date and will forever be is the rent that they pay to stick to that location. the other difficulties include the excess storage of items and stock and at the same time paying the staff around.

Have you tried searching sites like Alibaba and Globalspec? Also, are you interested in laser or needle perforating?

For the Rz, by its definition, you do not need to measure all peaks and values, just the 5 biggest of each, in absolute terms. See: http://vn.misumi-ec.com/pdf/tech...

If your measured profile (or, more precisely, your upper cut-off length Lc, which is taken as the basis of roughness calculations) is not long enough to contain 5 peaks or valleys, then it is unfit for purpose and should be increased.

Depending on where they came from, metallic samples are not necessarily homogenous, so hardness will vary. Microhardness testing, which tests the material at a much smaller scale than its macro counterpart, will register greater differences. Usually there is a steep gradient near the surface, due to work-hardening or even explicit case-hardening processing. The hardened zone varies in depth and is wider for forged or drawn surfaces than machined ones. You can check this if you measure very close to the edge of the transverse section of your sample.
