The Liquids Pack contains 4 bottles of proprietary fluids used in the etching of copper from the Graphene-on-Copper Disks. The Liquids Pack has a capacity for seven GLC fabrication runs, amounting to a maximum output capacity of 35 GLC grids per Fluids Pack.

VitroTEM supplies a variety of commonly used buffers for the final stage of GLC assembly. During loop-assisted transfer of graphene onto the grid, minor dilution of the sample cannot be avoided. The use of buffer at this stage of the assembly ensures that the buffer composition and concentration in the final liquid cells is not affected. The Naiad also allows the use of users' own custom buffer or medium.
