Alliance 2695 Alliance HPLC System, Waters (CAT#: STEM-CPO-0763-ZJF)

The manufacturer of the Alliance 2695 Alliance HPLC System, Waters is Waters.
Refurbished Waters 2695 Alliance HPLC complete with Waters 2487 dual absorbance detector (p/n WAT081110), Waters TC2 temperature controle module (p/n 186002441), Waters column heater module (p/n CHM) and Masslynx 4.1 PC workstation.
The Waters Alliance 2695 Separations Module is a high performance liquid chromatographic system with a quaternary, low-pressure mixing pump and inline vacuum degassing. Flow rates from 50 uL/min to 5 mL/min can be generated for use with 2.1 mm ID columns and larger. The autosampler has a maximum capacity of 120 vials (12x32, 2-mL) with programmable temperature control from 4 to 40°C. A heated column compartment provides temperatures from 5 degrees above ambient to 65°C. The detector is a photodiode array (model 2996) with a wavelength range of 190-800 nm and sensitivity settings from 0.0001-2.0000 absorbance units.
