A disposable solder receiving capsule for a hand held vacuum solder extracting desoldering tool is formed of an outer tube which is closed at one end by a porous filter and has an opening at its opposite end, and a hollow solder collection chamber part, having a tubular member with an open end and which is closed with respect to the passage of solder therethrough at an opposite end, forming a solder receiving space within it. The solder collection chamber part is concentrically positioned within the outer tube with an air plenum disposed between the closed end of the chamber part and the filter and with at least one air channel extending the length of solder collection part for providing a path for gases entering the open end of the outer tube to the plenum and the filter that is separated from the solder receiving space. For facilitating solder reclamation, the capsule can be formed entirely of materials which are shape-sustaining when exposed to a temperature of 400&deg; F., are not reactive with either solder and flux, which will burn with little or no residue at a temperature less than 800&deg; F. A desoldering tool for use with the capsule has a detachable, tubular capsule holding part that is open at each of its opposite ends for enabling a solder receiving capsule received in it to be removed from one of the end of the holding tube by pushing another soldering capsule into the opposite end of the holding tube when the detachable holding part is detached from the body of the desoldering tool. In a most preferred embodiment, the tool is designed so that solder cannot be drawn into it if the capsule has not been inserted or has been inserted incorrectly.
