The Barri pharmacy, dating from the early 20th century and run by Lluís Barri i Caballé, has been fully recreated in the museum. These marble and metal scales are among the items that were used by the pharmacist. The brand name is still visible: Vellar Barcelona. The model is based on the Béranger design, a type of scales that reduced the friction of the plates. These scales would be later replaced by automatic ones, while those used today have electronic components.
