Scientific Citations

  • The Hamilton venting needles allow performing precise dosing of solutions.

    In automation, sealed vials present problems with positive/negative pressure when trying to aspirate and dispense liquids. The Hamilton venting needles allowed us to perform precise dosing of solutions and solvents in crimp capped GC vials. The ratio of dispensing was critical for the final sample prior to HPLC analysis.
