Water, LC/MS grade


Ideal for HPLC, mass spec (MS) and spectrophotometric detection.

Thermo Scientific Pierce LC/MS Grade Water is specially purified by a proprietary method and tested to ensure lot-to-lot consistency with a low UV absorbance to provide you with the most sensitive detection across all wavelengths. Pierce Water is 0.2-micron filtered, packaged in solvent-rinsed amber glass bottles and sealed under a nitrogen atmosphere with Teflon TFE-lined fluorocarbon caps for ultimate protection.
