UniverSol? is a very efficient environmentally safe, non-toxic, biodegradable liquid scintillation cocktail of the “gelling” variety.

The physical characteristics of UniverSol? ES are identical to traditional “TRITON? and Toluene” type commercial cocktails. Aqueous samples from 0-15% load capacity count as a clear solution. Samples with high ionic concentrations will count most efficiently in this region. From approximately 20% to near 40% load capacity, UniverSol? ES becomes a translucent gel, useful in suspending particulate samples or samples that phase due to salt concentration or molecular size. UniverSol? ES has been formulated to work over a wide variety of laboratory counting requirements. NOTE: high concentrations of salt, protein, and sucrose will affect the sample solubility, as well as, the physical characteristics of a surfactant cocktail. By diluting UniverSol? ES with distilled water, usually from 2-5% by volume, these concentrated solutions which would normally precipitate can be counted as clear homogeneous solutions.

Primary Applications: Aqueous samples from 0 to 15% count as monophasic solutions. High ionic concentrations will be most efficiently counted in this region. Also, for use under controlled chemiluminescence when high tritium efficiency is desired.
