Repeat 3 and 46. Immerse in SAM solution<b>Glassware Cleaning</b>1.If visibly dirty wash vial as normal glassware then sonnicate in EtOH for half hr2. Immerse glassware in Piranha solution for 1hr3. Remove and wash with copiuos amounts of UHQ water (x4) to remove acid4.Sonnicate in UHQ for 30min5. Wrap in tin foil and dry in oven for 1hr untill dry6. take out oven, cool in foil then immerse in HPLC EtOH and sonnicate for 30min7. Wrap in tin foil put in oven and use within a week</div>
