2.5 mL, Model 1002 GF HDHT Headspace SYR, Glue Free NDL, 26 ga, point style 5 -200 °C-. 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.
