The term labscale is informally used to refer to small-scale x-ray instruments used for diffraction or scattering, in comparison to synchrotron beamlines. These may also be called in-house of benchtop instruments.

Labscale instruments typically use a rotating anode as an x-ray source. Their flux is much lower than a synchrotron (which is 3-6 orders-of-magnitude brighter); e.g, 107 to 108 photons/s. Labscale instruments also typically haver larger beam sizes, worse resolution, and lower coherence. Nevertheless, useful data can be obtained on many systems, especially strongly scattering samples.
