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
)ossible to Tnake.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 "zero" with a leaktight seal. And, you 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 permanently staked onto the plunger. Each syringe is individually assembled and the plunger fitted by hand to exceedingly close tolerances. Then they are tested for leaks with acetone at five

used why the scientific "community has relied on the accuracy of Hamilton syringes for two decades. And that's a reputation we don't take lightly. And, finally, the price. A Microliter® 701Ν was $18.00 in 1958...and it's still $18.00 in 1978. Only by constantly developing our manufacturing skills and improving our speed of pro duction have we been able to offset the rising costs of material and labor. That's what you can't see when you look at a Hamilton Syringe. The con cept. The commitment. The pride. But, they're more important to the quality of a syringe than the materials
or produc tion process. They are what' has mad Hamilton syringes the world's standard precision liquid measuring device For a free copy of our current catalog write to Dept. A, Hamilton Company, Post Office Box 10030, Reno, Nevada 89510.
