Vacuum Pump by PixiiEntry/Object ID
2013.3.88Description
Description from L.A. Brown's 1959 catalog: "This is the oldest pump we have. It probably was bought by Dr. Caldwell in Paris in 1821 from Pixii. In 1821 the head of this well known firm was officially listed as "neveu et successeur de Dumotiez." Note that this pump and the one shown in the Figure 81 are operated by an up and down motion of a two handed handle pivoted at the center. This Pixii Air Pump is illustrated by Robert Hare (Compendium of the Course in Chemical Instruction, etc., Philadelphia, 1836). It is spoken of in this text as 'a very fine instrument of large size.'"Collection
