SYR,1002 HDHT HEADSPACE,23 PT5 SC: B BC: CE ST Hamilton
Hamilton engineers realized that the easiest way to increase the temperature limit was to remove the cement that holds the needle into the barrel. They developed a connection that crimps on to the end of the glass barrel and improves chemical compatibility with a PTFE seal. This new needle design was tested alongside the High Dynamic (HD) spring loaded plunger to a temperature of 200°C. The resulting syringe design almost doubled the headspace operating temperature and opened up a new world of compounds from analysis.
