Disposable polystyrene cuvettes are not resistant to organic solvents, thus
non-water based samples should generally be measured in glass or quartz
type cuvettes.
The optical quality of the cells is vitally important when performing molecular
weight and protein measurements, therefore glass or quartz type cuvettes should
be used to ensure the optimum signal is achieved.
All the cells mentioned below are available from Malvern and should be used
with the supplied cell caps. Using the caps will ensure greater thermal stability of
the sample, as well as preventing dust introduction and possible spillage.

Due to the risk of melting, polystyrene cuvettes must not be used for
measurements above 50°C.
