Reno, Nevada (May 5, 2010) – Hamilton Company, world leader in fluid measurement, introduces a new line of rugged syringes specially designed for optimal performance and long life in Spark Holland HPLC Autosamplers. These new GASTIGHT® syringes are ideal for dispensing liquid samples from a wide range of matrices and solvents. The PTFE (polytetrafluoroethylene) construction of the syringe plunger tip ensures a precise fit with the glass barrel, creating a leak-free seal for accurate operation. Hamilton GASTIGHT models are particularly well-suited for use with heterogeneous samples, which can cause syringe plungers to freeze.
