I have read in a paper (PMID: 17056667) : “the pipette was coated with sticky wax close to the tip to reduce capacitance”. What is this wax and what is it for exactly? How do we apply it to the patch pipette? Where can we get it?
In the same paper: “a 1M NaCl-agar bridge between the bath and the Ag-AgCl reference electrode was used to minimize offset potentials (<2 mV)”. Where can we get this bridge? How do we install this bridge? Can anyone send me a photo showing that bridge installed?
Thanks in advance
