Why can't the small caliper measure the small hole?

In the inspection work, the measurement problem of the small hole is often encountered. Some inspectors directly measure the small-sized inner hole of φ10 mm or less with a knife-shaped inner claw of a three-way vernier caliper with a graduation value of 0.02 mm at the time of detection, and often find that the smaller the hole, the more difficult the dimension is to be measured. However, the correct measurement position is neglected so that the direction of movement of the gage probe is consistent with the direction of the measured dimension. I wanted to make the measured pore size close to the real value, but

Cell Culture Flask

The in vitro culture of cells and tissues has become an indispensable part of life research and practice. A wide variety of cell types are cultured, from viruses to bacteria and fungi, from human cells to animal and plant cells. Some cells and tissues can be grown in suspension, but a considerable number of mammalian cells require surface attachment. Therefore, in addition to good transparency, non-toxicity and sterility, the culture flasks, Culture Plates and culture dishes used to provide the in vitro culture environment of cells also need to be surface-modified to enable them to adhere, divide and grow.
