Kipp Chem.|kɪp| The name of Petrus Jacobus Kipp (1808–64), German chemist, used in the possessive (less commonly absol. or attrib.) to denote an apparatus for the generation of gas by the action of a liquid on a solid as and when gas is required. The apparatus consists essentially of three glass bulbs, of which the upper and lower ones are connected and contain the liquid and the middle one is connected with the lower one and contains the solid; while a tap in the middle bulb is open, liquid rises into the bulb and gas is evolved, whilst closing the tap causes the pressure of the gas to increase until the liquid is forced out of the middle bulb into the lower and upper ones, out of contact with the solid.
1879Proc. Cambr. Philos. Soc. III. 160 A gentle current of hydrogen from the Kipp's apparatus A..was led into D. 1901F. G. Benedict Chem. Lect. Exper. 3 The Kipp generator, or one of its various modifications, remains today the only portable gas generator for the lecture table... The simpler and less expensive the form of Kipp used, the better. 1912J. W. Mellor Mod. Inorg. Chem. iii. 45 Kipp's apparatus is very convenient when a steady current of hydrogen is needed for some time. 1921J. R. Partington Text-bk. Inorg. Chem. xi. 185 Instead of a flask, a Kipp's apparatus may be used, the metal being placed in the central globe B and acid poured in the top funnel until the lower bulb A is full and the metal covered with acid. 1965D. Abbott Inorg. Chem. xi. 535 It [sc. hydrogen sulphide] is most conveniently prepared for laboratory use in a Kipp's apparatus by the action of dilute hydrochloric acid on ferrous sulphide. |
