Our group has a well-equipped synthetic laboratory with a set of fume hoods, Schlenk lines, magnetic stirrers, rotary evaporators, and more specialized synthetic equipment.
Gloveboxes: MBraun LABStar Glove Box (single workstation) and Inert PureLAB (double workstation) with an organic solvent purification system (methanol, acetonitrile, tetrahydr.ofuran, pentane, diethyl ether). These systems make it possible to perform synthesis in anhydr.ous, anaerobic, and aprotic conditions, and to work with compounds highly sensitive to ambient conditions (oxygen, moisture).
