Simply mix the honey with sterile bidest. water using a stirrer.

Dear Dr.Abdelilah,

You need to dilute a honey with boiled, but only cold water, since into hot water honey became toxic. Dilution is one to one. Good luck !

Thank you

are you looking at possible residues left by beekeeping practices or to natural substances included in honey with bacteriostatic activity?

which lab instrument and which class of molecules are you looking at?

In case you're looking for residues, there's no need to dilute the honey, cause the dilution will be provided by buffers you use in your protocols (i.e. HCl, acetone for sulfonamide based in HPLC or McIlvaine's buffer for Tetracycline in LC-MS/MS).

There are various protocols.. but in general there's no need to dilute honey
