Round Bottom Flask,Short Neck With Beaded Rim
Laboratory Glasswares
Introduction:
Round Bottom Flask,Short Neck With Beaded Rim
The flask made of borosilicate glass with permanent graduations. They have a low coefficient of expansion and are thermal shock resistant.Features:
High-borosilicate glass: BJTY glass is accord with ISO3585 and ASTM E438 level I A standard for the coefficient of expansion of 3.3 high-borosilicate glass.
BJTY glass with the best chemical stability, low expansion coefficient, can process performance and high temperature resistant impact as the main characteristics, and has a strong resistance to water, acid and alkali, such as performance, and become a laboratory instruments, chemical corrosion resistant glass equipment and heat-resistant glass vessels products are the most ideal material
