A complete integrated table-top facility for the study of high-$Q$ WhisperingGallery Modes in solid and liquid micro-cavities is described, with emphasis onthe in situ fabrication of reliable tapered fibers of sub-micron waist sizesfor coupling light into time-dependent liquid micro-cavities. The experimentalparameters have been chosen to get nearly adiabatic tapers, with their waistsize consistent with the theoretical model. The oscillations in the transmittedpower during fiber tapering are monitored to check the coupling of higher ordermodes and identify the point when the fiber is suitable for pure single modecoupling. The fabricated tapered fibers have greater than 85% transmission onthe average and very good polarization fidelity. The tapered fibers have beenused for efficiently exciting and detecting WGMs of $Q\sim10^7$ in silicamicrospheres and of $Q$ up to $7\times10^7$ in microdrops of silicone oils.
