Hamilton Company GC Autosampler Syringe 203141

Modern GC Headspace analysis requires injecting over large temperature ranges (e.g. ITEX analysis). Traditional headspace syringes come with a rubber O-ring sealed plunger which has a limited sealing performance at high temperatures. The high dynamic HD-Type syringe employs a unique spring in the plunger tip which compensates for the materials’ different expansion coefficients, creating a better seal over a larger temperature range, and it also improves lifetime.
