hydrophobic coating on the inside to prevent liquid from being drawn into the capillary, which would interfere with the results. The TO2032 coating set is available for the occasional renewal of the coating.
The set contains a capillary holder for up to 5 capillaries, which is placed on the vessel you are using with a silanizing agent. A fitting grinding block is used to grind the capillary tips evenly at the end of the treatment.
KRÜSS recommends the product “Silanization Solution I” from Fluka as silanizing agent.
