Unquenched

This unquenched Liquid Scintillation Counting Set of 3 Standards contains 1 Carbon-14, 1 Tritium (H-3) and 1 Background Standard.

The set is designed  for establishing  the optimum  LSC operating settings and verify long term stability. It can be used with all common LSC instruments. Each source is calibrated, measurement uncertainty <4% (k=2).

The standards are available in 20 ml and 7 ml Argon purged, flame sealed borosilicate glass LSC vials.
