Cell recognition
Automatic for most types
*
Depending on the wavelength range, different kinds of cells are suitable. Suitable are
round cells, all rectangular cells of glass, quartz or plastic, whose side surfaces are frosted
(see Section 8.1). Cells with clear or serrated lateral surfaces are not reliably recognized
by the automatic cell recognition.
Especially with plastic single-use cells we recommend you test them for suitability prior to
carrying out large-scale series of measurements.
For measurements in the UV range below 320 nm, glass cells and commercial PS plastic
cells are not suitable; below 280 nm, commercial PMMA plastic cells are not suitable due
to their transmission characteristics. Therefore, use quartz cells or tested single-use cells
(plastic) for applications in the UV range.
