Description
This Walter Products S900 spectrophotometer is equipped with two single-position
cell holders for 10mm cells, and features a large sample compartment for up to
100mm path length cells. The multi-wavelength can work with up to 32 (can be more)
wavelengths.
Its many functions include basic photometric mode, quantitative analysis, kinetics test,
measurement and multi-wavelength tests and more.
The large 9.7” LCD touch screen panel allows for more room to work with, and a clear
and easy reading of absorbance, transmittance, factor, and concentration levels. Built
with an Android operating software and it also
supports Wi-Fi, Bluetooth, and USB storage.
The pre-aligned lamps are conveniently placed
for easy replacement, while the optical parts
are mounted on an aluminum foundation which
provides a steady and firm base. It is ideal for
students to use in college, university, and general
laboratory settings.
