We have an LGR liquid water isotope analyzer and have been buying the 1.2 microlitre syringe from LGR. Firstly their sales department sucks. I know these syringes are made by Hamilton. Has any one experience with ordering these directly from Hamilton and if so can you please send me the part number and a web link? I was also told that LGR buys these from Hamilton and charges a higher price when you buy from them.  Please email me at [log in to unmask] Thanks
