A rare set of three antique hand-blown glass stalagmometers, carefully housed in their original blue velvet-lined case. These scientific instruments measure the surface tension of liquids using the drop-counting method (Tate method). Each finely hand-blown tube features a central spherical reservoir and precise graduations. Two of them have an angled opening, facilitating their use on a vertical stand in the laboratory. A rare collector's item in perfect condition, a testament to the history of experimental physical chemistry.
