The Lambda 365 is a double-beam UV-Visible spectrometer that measures light absorption from the visible to the ultraviolet region of 190 nm to 1100 nm (6.5 eV to 1.1 eV). A sample is usually made up to a known concentration in a non-absorbing solvent (such as water) and loaded into a quartz cuvette (available from the lab). Liquids, solutions and transparent solids can be measured. Note that we are not able to measure reflectance on this instrument.
- Standard sample solutions: 10 mm pathlength cuvettes including stoppers for air-sensitive work
- Small quantities: 1 mm pathlength cuvettes and 1 cm minimum-volume cuvettes are available
Solids: a sample holder for measuring transparent solids and thin films on solid substrates such as glass.
