As per my understanding or faded memory formaline decolourises the specimen and makes it brital too. Even alcohol has to be used with some % of CuSo4. Remaining may ask someone and let you know. Madhuri Sent from BlackBerry® on Airtel

Its alcohol content is ethanol.... but I GUESS IT WOULD NOT DO ... since its only 40%... so I guess I am to try and find Spirit from pharmacists... BUT NOWADAYS the alcohol availbale for cleaning injection sites etc is Isopropyl alcohol really... which carries its own toxicity for humans, but our regulators are not concerned with that at this point...I am goint to write that up elsewhere... BUT FOR THIS group... my next question is , suppose I did find the rectified spirit, and made 70% with WATER? or do I need to buffer it, like we do for human tissues preservation when using formalin? Can buffered formalin be used for preserving flowers? So in summary I am asking two questions: Rectified spirit is to be diluted with what, and cand buffered formalin be used for flowers in particular and botanical specimen in general? Thanks..
