Abstract
Liquid scintillation counters are now the instruments of choice for use in counting most radioactive samples. While preferred, liquid scintillation counters are still subject to the disadvantages of their inability to effect high photon detection from within the counting vial, and of their inability to retain volatile cocktail solvents within the instrument for relatively long periods. A liquid scintillation counter is provided having a sample vessel with means which increase photon impingement on the photosensing device of the instrument, and with closure means better preventing escape of volatile materials.
