Does the quality and/or purity of a solvent change over time as the solvent is repeatedly recycled?
No. In fact, the recycled solvent usually is of a higher quality than the vendors originally-supplied starting-grade, due to the purification that results from the fractional distillation process that is part of the CBG Biotech recycling process. The solvents themselves are extremely stable and do not show any measurable decomposition even after many years of storage at elevated temperatures.
