<p>The syringe (1) has a cylinder (2) for accommodating liquid medicament, and a cone (3) comprising borosilicate glass having thermal expansion in the range of about 20 to 300 degrees centigrade of less than 6x 10 ->6/Kelvin. The cone encloses an outlet channel (4) and has an outside surface with a coating (5) exhibiting an increased roughness compared to the outside surface. The coating comprises a glass matrix with structure-forming particles embedded in the matrix, where the glass matrix is free of lead, cadmium, mercury and chromium VI. The coating has roughness of about 0.3 and 2 micrometer.</p> |
