title: Improved recovery of morphine from biological tissues using siliconized glassware.
abstract: The adsorption of morphine onto glassware during analysis in aqueous solutions and biological tissues is a common problem, resulting in lower recoveries than expected. The problem can be remedied by siliconization of all glassware involved. The same glassware cannot be used repeatedly without incurring a significant loss of morphine.
