Oolong Tea Extract (OTE) is a non-toxic and non-radioactive stain for electron microscopy. It is effective for fibrous connective tissues. OTE acts as a Tannin which allows complete post-stain lead citrate mordanting and gives satisfactory results. Powder is ideal for longer storage.

NanoSuit® is a novel technology to observe biological organisms, cells, bacteria, viruses or cellular compartments in a natural, living state using scanning electron microscopy (SEM). It forms a thin, conductive, moisture barrier layer between specimen and vacuum environment to hold moisture in the specimen. Simply drop the solution onto the object. No fixation or dehydration procedures needed.

Osmiophilic reagent. With the Thiocarbohydrazide it´s possible to enhance the contrast of all osmophilic components of the cell, especially lipids, which hold the most osmium.

An indefinite shelf life due to a special purification process.
