New Salt Line syringes for Trace Metals analysis

Many laboratories conducting metals analysis on environmental or clinical samples use the Hamilton 500 series diluter/dispensers, which have been proven to enhance their analytical efficiency and performance.
The inert fluid path of the Hamilton gas tight syringe, valve and tubing lines assure that when using diluents no interfering ions are added to the matrix, and prepare sample and standard dilutions with the highest level of analytical confidence. However it has been found that when conducting trace metals analysis, aluminum background levels exceed acceptable values when using nitric acid diluents.
This has been experienced when the syringes are used over long periods with nitric acid, due to the breakdown of the Teflon coating covering the aluminum alloy plunger of the standard gas tight syringe.
Hamilton Company has developed the new Salt Line syringes for longer plunger tip life expectancy for demanding automated dispensing applications.
The plunger tip is made of ultra-high molecular weight polyethylene, a harder material that provides longer plunger life, and the plunger has been developed using a proprietary high-density plastic.

These GASTIGHT syringes are the product of choice for Trace Metals analysis and the perfect solution for the preparation of standards and samples with aggressive acid diluents.
They are recommended for saline or other solutions with a pH range of 1-13 that may crystallize and scratch traditional PTFE plunger tips. Volumes range from 250 ul to 10 ml.
