Made of borosilicate glass, which is: thermal shock-resistant, light
weight, and scratch-resistant (making it more hygienic).
All of which is
why borosilicate glass is chosen for use in laboratories.
Ours is made in France, in a factory that has specialized in making
pharmaceutical glass for more than 50 years.
All parts are BPA-,
phthalates-, polycarbonate- and PVC-free.
Glass is a natural resource; the safer option to plastic baby bottles (Even BPA-free plastic bottles may leach toxic chemicals).
