Waters
2790 Alliance
$19,900*
This
Waters 2790 Alliance is in excellent condition
and has been fully tested at GenTech Scientific. It
is an integrated solvent and sample management platform
which combines two traditional high-performance liquid chromatography
(HPLC) components: a solvent management system and a sample
management system. Includes NINETY
(90) DAY WARRANTY.
*All
prices are in U.S. dollars and do not include shipping,
handling and installation. International
