I recommend filter sterilization (0.2 um filter unit) instead of 
autoclaving, and storing in sterile glass bottles.

Regarding 50% w/v solutions ... takes a few hours to dissolve. Thus, 
start early in morning ... if stirring overnight, tightly cover opening of 
vessel (erlenmyer flask is preferred)  with clingy plastic (Saran-type) wrap.
