16 PRODUCTION 12 QUALITY 67 INDIVIDUAL FOR ONLY When you look at a Hamilton Microliter® Syringe, it looks like just a simple syringe. Some glass, a needle, and a plunger. Just one moving part. But, looks can be deceiving. Producing a syringe to the quality standards we've set for ourselves is no simple task. It begins with a concept: To make the finest precision syringe that it is possible to "make.· To achieve that goal · requires a commitment to quality. That means starting with only quality materials: • pharmaceutical grade glass and fine stainless steel. It also means trained craftsmen. Here are a few of the operations through which a Microliter® syringe goes.
The barrel is annealed to relieve strains, the flange is formed lovingly by hand, and the graduations are carefully etched into the glass by ionic reaction with silver nitrate...in all, some 36 individual operations are performed on the glass. The needle is 304 stainless steel that is electrolytically tapered^ at the
point. It is carefully cemented with epoxy at "zei with a leaktight seal. And, yo have your choice of four point styles, ground and polished to aid penetration. The plunger steel is straightened by precision machines and centerless ground. The button is perma nently staked onto the plunger. Each syringe is individually assembled and the plunger fitted by hand to exceedingly close tolerance; Then they are tested for leaks with acetone at five
