Using printing solutions

A printing session requires two solutions:

  • chamber solution
  • iontip ink

Each solution should be handled accordingly to local regulations wearing the proper safety equipment.

Equipment needed

  • 0.1-5 ml, 1-100 µl and 0.1-10 µl micropipettes
  • 2 ml syringe
  • 200 nm (or less) pore size filters (hydrophilic)
  • 2 ml vials

Printing Copper

Using the chamber solution [Cu]

The chamber solution [Cu] can be used as received. 10 to 12 ml of the solution can be pipetted into the assembled printing chamber or replaced when needed. The chamber solution [Cu] should be changed daily. The used solution must be disposed according to local regulations. Remember to also setup the PSTrace software if not done already, applying a potential of -0.5 V.

Using the iontip ink [Cu]

The iontip ink [Cu] must be filtered before use using the provided syringes and filters. When using the iontip ink brightener [Cu], 20 µl of each component (A, B and C) must be added to 1 ml of iontip ink [Cu] using the provided micropipette. Micropipette tips are single use and must be changed for each component. The mixed iontip ink brightener [Cu] filtered before use using the provided syringes and filters.

The probe can then be filled with 0.2 to 1 µl of filtered ink.

Solution supplies

Solutions described here can be ordered at Exaddon or via your local distributor. A step by step guide on how to prepare basic versions of the chamber solution [Cu] and iontip ink [Cu] can be found here.
