Katalin Karikó believes that she has been her most used tool in her research career. It is used to draw small amounts of liquids. This particular pipette, marked with a piece of tape, is her favourite. She used it for about 10 years from the early 2000s. She sees it as a symbol of her research findings that set the stage for the mRNA vaccine.
Katalin Karikó donated the pipette to the Nobel Prize Museum in 2023.
