Mineral oil-based Liquid Scintillators

Mineral oil-based liquid scintillators are used in large tanks where exceptionally long mean free paths are essential and high light output is of secondary importance. These mineral oil scintillators are compatible with acrylic plastics such as Plexiglas® and Perspex®, plus a wide variety of metals and some other plastics and reflective coatings. Glue joints made with solvent action cements should be annealed.


Saint-Gobain Crystals mineral oil scintillators have flash points rendering them relatively safe for use in large containers and large-volume detector arrays. They are especially suited where the expense of large-area plastic scintillators would be prohibitive.


We take special care when manufacturing its mineral oil liquid scintillators. Our people are keenly aware of the particularly high requirements regarding light transmission and product uniformity demanded by the physics community. Therefore, in addition to employing standard, rigorous purification and handling techniques, SGC uses special test facilities for light transmission measurement in order to guarantee customer satisfaction with every shipment of this scintillator.
