PROBLEM TO BE SOLVED: To provide a chemical resistant syringe that can discharge a trace amount of fluid. SOLUTION: A body 1 has a hardware 2 for reducing its inside diameter attached by a locknut 8 at its end and has the syringe 4 inserted through the penetrating hole 3. The syringe 4 is tube-shaped and made of a transparent resin material such as PFA with its one end narrowed to form a nozzle 5. A round-bar-shaped piston 6 has a little smaller outside diameter than the inside diameter of the syringe 4 and is inserted from an open end 7 of the syringe 4. With the locknut 8 tightened, the body 1 has its inside diameter reduced, holds the syringe 4 tightly and even reduces the inside diameter of the syringe 4 to form a seal part 9. The tightening force of the locknut 8 is adjusted so that the piston 6 may slide back and forth. COPYRIGHT: (C)2007,JPO&INPIT |
