Instructions for use
Analysis of sodium, iridium, titanium, zirconium and perchlorate; raw materials for the preparation of metal rubidium by calcium reduction and for the preparation of other rubidium salts and isotopic separation. Mainly used for electrolytic preparation of metal rubidium, and also used for aluminum flux.
Generally, RbCl can be used as an electrolyte for water.
Nanowires, an electrochemical probe, were placed on mica with diluted RbCl and showed good directivity.
RbCl transformation (transformation) competent cells (competent cells) can be said to be the most abundant application of this compound. Cells were treated with a hypotonic (en:hypotonic) solution containing RbCl. Thus, membrane proteins are removed and negatively charged DNA is allowed to bind.
