5mL #24 Volatile Oil Measuring Tube Receiver Volatile Oil Measuring Instrument

Material: borosilicate 3.3 glass
Borosilicate 3.3 glass (also known as hard glass) :
Is the use of glass in the state of high temperature conductive characteristics, through the glass internal heating to achieve glass melting, through advanced production technology processing, because the line thermal expansion coefficient is (3.3±0.1) x10-6/K; It is also called "borosilicate glass 3.3". It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability.
