Measuring Cylinder 10ml Borosilicate Pack of 2

Thermal shock. Ordinary soda glass cracks when the temperature changes quickly; borosilicate does not. In a school lab, where glassware gets rinsed under a hot tap and then used cold, that is the difference between one purchase and several.

It is the accuracy the cylinder is manufactured to: 0.20ml. If a student measures 10ml in it, the true volume is within that margin. It is worth showing senior students, because it is where the idea of measurement uncertainty stops being abstract.

A pack of two. They are not sold individually in this line.

At eye level, from the bottom of the meniscus - the curve the liquid makes at the surface. Reading from above is the most common source of error in a school lab and it always reads high.

No. Borosilicate handles thermal shock, but a measuring cylinder is a measuring instrument, not a heating vessel. Heat in a beaker, then measure.
