ABSTRACT:
An instrument for viewing samples contained in capillary tubes under optical magnification. The sample-containing capillary tube is disposed in a holder within the instrument wherein the sample is illuminated for viewing. The illumination system allows for epi-illumination or trans-illumination of the sample. The sample holder is a transparent member which has a slot in which the capillary tube is held. Oil or water is disposed in the slot to lessen the lens effect of the curved wall of the transparent capillary tube.
