✦ Synopsis

Small glass shell vials (12 X 35 mm minivials), containing 2.0 ml of a dioxane-based scintillation solution plus a' V-labeled sample, were placed in a conventional glass, 20-ml count vial and assayed in a scintillation spectrometer. Statistical comparison of counts recorded from 14C samples prepared both in the minivial system and conventional 20-ml count vials indicated that the two systems were equivalent with sample volumes of 10 and 109 pliters (16OO-cpm solution)

and 10 &liters (6O-cpm solution). Conventional 2O-ml glass or plastic count vials were both acceptable as containers for the minivials.

There were no significant differences in the counts from samples in minivials placed on-center and off-center in the container vial. Cost per sample was reduced from 24.8 cents (conventional glass vials) to 4.7 cents (minivial system).
