Dear colleagues,
does any of you by chance have in your private stocks any of the following substances (not available in the common chemical storage):
* MnCl2.4H2O * ZnSO4.7H2O * Na2MoO4.2H2O * Na2SeO3.5H2O
my needs are for several grams of each and the stock solutions are very concentrated; once prepared, I will not have the need for these chemicals for quite some time… so I would be very grateful if you could spare me the ordering and let me have some grams of yours 😊 Many thanks in advance!
Have a nice autumn holiday!
Best regards, Kaloian Nickolov
