Abstract
The development of syringe tips
In 1927, Watson produced the first syringes used for instrumental insemination of queen bees. They were made of glass, and each had a permanently attached glass capillary tube with a hand-drawn glass tip which served both for semen collection and semen injection Ten years later, Nolan, using Watson's glass syringe as a model, simplified the syringe design using a modified mechanical pencil and a glass capillary tube
