Q Band Standard EPR Tubes

Description

EPR Tube Q-band is the most popular frequency for pulsed and cw-EPR after X-band. The larger Zeeman splitting would benefit EPR studies by (1) improving SNR, (2) requiring less sample, (3) resolving individual components of the g-matrix, (4) disentangling spectra which overlap at X-band, and (5) changing the spectral contribution interaction to field-independent interactions.Wilmad-LabGlass offers high quality EPR consumables to cover these high frequency applications.
