Abstract
Syringes for holding fluids susceptible to void formation when the syringe and fluid are frozen and thawed before use. The interior surface of the syringe barrel is modified by exposure to a plasma such that the incidence of void formation in the fluid is prevented or, at the least, significantly reduced in comparison with conventional syringes.
