Abstract: An apparatus having a plurality of phase change material-containing wall panels. The wall panels have a thickness and sides. The wall panels define an inner major surface and an outer major surface. The sides of the wall panels are hingedly interconnected to define a closed structure. Two diametrically opposed hinge interconnections are proximate the inner major surface. The remaining hinge interconnections are proximate the outer major surface.

Abstract: Contiguous capillaries useful for separating and electrospraying a fluid comprising analyte and electrolyte are provided. The contiguous capillaries have spray tips at one end of the capillaries and electrically conductive portions in proximity to the spray tips. Methods for making the contiguous capillaries and their use as electrospray sources are also disclosed. Apparatus and methods for conveying analyte ions from the capillaries into analytical instruments, such as a mass spectrometer, are also disclosed. The disclosed contiguous capillaries may be used to carryout electrophoresis separation and electrospray ionization of analytes. Methods for obtaining the mass spectra of macromolecular analytes at concentrations lower than previously possibly are provided using the apparatus and procedures described herein.

Abstract: A unitary multi-purpose tool cuts, strips and twists together wires for example in preparation for the installation of insulating cap-type twist-on wire connectors.
