Before the development of other means of pumping to very low pressures, the technique of producing a high vacuum by absorption of the gases on activated charcoal was very frequently used. (...)

A question nouvelle :"l'éponge à molécules". Cette éponge n’ est autre qu'un bloc de carbone très poreux, du charbon actif qui possède la propriété lorsqu'on le refroidit à-196 °(température de l'azote liquide) de "geler" toutes les molécules, c'est-à-dire de les obliger à se condenser à la surface. 3, record 2, French, - %C3%A9ponge%20%C3%A0%20mol%C3%A9cules
