A GLASS ELECTRODE APPARATUS FOR MEASURING THE pH VALUES OF VERY SMALL VOLUMES OF SOLUTION
A glass electrode apparatus is described with which pH measurements can be made with as small volumes as 2 drops (about 0.14 cc.) of solution. Using this apparatus the change of pH of the vacuolar sap of Nitella, due to the penetration of brilliant cresyl blue, has been readily followed. The sap and the dye have been found to poison the usual type of hydrogen electrode.
متن کاملA simple glass-coated, fire-polished tungsten electrode with conductance adjustment using hydrofluoridic acid.
A method is described to produce glass-coated tungsten microelectrodes in 4 simple steps: (1) etching of the wire, (2) coating with glass, (3) fire-polishing, and (4) reopening with hydrofluoric acid to adjust the conductance to a final value. Continuous conductance control is provided during the reopening process by means of an admittance meter to guarantee an exact final adjustment of the con...
متن کاملCxli. the Technique of Glass Electrode Measurements
IN the course of an investigation into the value of the glass electrode as a means of making continuous records of the hydrogen ion concentration of circulating blood, it was found, in the preliminary experiments in which estimations were made on single samples, that there were several sources of serious error. The difficulties encountered in devising a satisfactory apparatus for measuring glas...
متن کاملThe glass transition in a simple model glass: numerical simulations
In order to improve our understanding of the glass transition we performed constant-energy molecular dynamics simulations on a soft-sphere system quenched from the liquid state to zero temperature. The temperature dependence of static (radial pair distribution function) and dynamic quantities (self-diiusion constant) has been investigated together with the temperature evolution of relevant stru...
متن کاملA simple cuff electrode for nerve recording and stimulation in acute experiments on small animals.
We describe a cuff-type electrode specifically designed for recording from, and electrical stimulation of, cut nerves in acute experiments on small animals. Unlike existing designs of cuff electrodes, it is simple to manufacture, inexpensive and takes little time to implant. The electrode was tested on the hypoglossal, phrenic, recurrent laryngeal, and superior laryngeal nerves in anesthetized ...
