<p>PURPOSE: A borosilicate glass syringe with a cone coating capable of the surface roughness is provided to maintain adapter located on cone reliable and to be closed while having sufficient sealing effect. CONSTITUTION: A borosilicate glass syringe(1) with a cone coating capable of the surface roughness comprises a cylinder(2) for accommodating liquid, a cone(3) with a boron silicide glass with a thermal expansion coefficient of 6*10^-6/K or less at 20-300°C. The cone surrounds an outlet channel(4) and has a coating at least in regions. The coating has an increased roughness relative to the uncoated surface of the cone. The coating includes a glass matrix with a structure-forming particle dipped in. The coating does not contain Pb, Cd, Hg, and Cr^VI.
