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. [Reference numerals] (AA) Longitudinal section view for the front part of a glass syringe with a cone and cone coating with a width, b본 발명은 붕규산염 유리로 구성되고 이송 어댑터 및 바늘의 고정 또는 장착을 위한 콘을 가진 주사기에 관한 것이다. 콘에는 거칠기를 증가시키는 코팅이 제공된다. 거칠기는 유리 매트릭스에 매립된 구조 형성 입자에 의해 달성된다. 코팅에는 중금속 Pb, Cd, Hg 및 CrVI이 없다.
