Scientific curiosity: Flask "Kidneys - Immunized monkey" (f45)

A scientific curiosity from the early 20th century, this small transparent glass laboratory flask is preserved with its original cork stopper, also annotated. The handwritten label mentions "Kidneys - Immunized Monkey", accompanied by a dilution or series indication "1 / 1,000,000" and the year "1913". This inscription refers to experimental work in immunology, likely related to the study of immune response in animal models. The use of monkeys, associated with the concept of immunization, reflects advanced research for the time, in a context of developing serums and early therapeutic approaches against infectious diseases.
