Method of filling a glass microelectrode NaCl solution

摘要

A method of filling glass microelectrodes NaCl solution by capillary forces, characterized in that! in aqueous 1 M NaCl solution was added to agar mark "ultrapure" to a concentration of 2.5%! the resulting solution-suspension is stirred 30 minutes! was heated at 25 ° C for 3 days,! bottled and refrigerated at 5 ° C for 2 days,! vials were then heated in a water bath at 50-60 ° C until ready for filling, is determined visually by the color change of the solution from the white to pale straw.
