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
