About Boiling Flask

Product Details

Boiling

Borosilicate glass has excellent chemical and physical properties.The linear expansion cofficient 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.

Product Specification

The dimensions are all measured by hand, so there may be some errors. Please contact us for the specific freight.
