PCT No. PCT/SE95/00227 Sec. 371 Date Nov. 4, 1996 Sec. 102(e) Date Nov. 4, 1996 PCT Filed Mar. 3, 1995 PCT Pub. No. WO95/23770 PCT Pub. Date Sep. 8, 1995A method for producing at least one capillary in a moldable material. The capillary has a large length in relation to its cross-section. A closed cavity is created within the moldable material and the material is stretched in at least one direction so that the cavity forms a substantially elliptical or parabolic capillary whose length is large in relationship to its cross-section. The material may be heated before stretching so that the cavity is expanded and shaped into an essentially spherical form. Suitable materials for the practice of the invention include glass, plastic, quartz, silicon, or metal. |
