Borosilicate glass has excellent chemical and physical properties.As described in the International Standard DIN ISO 3585, the linear expansion coefficient of the primary hydrolyzable glass is 3.3 for applications requiring excellent chemical resistance and thermal resistance (including thermal shock resistance), as well as high mechanical stability. It is a typical glass for chemical equipment.
Clear scale .
Printed scales are clearer and less prone to wear.Pipette mouth section is smooth and round,beautifully made.High transparency, more intuitive to observe liquid.
