Samples can be prepared and stored using commercially available
materials, handling procedures, and storage equipment. Typically,
a buffer solution is made, the conductivity and pH are adjusted,
and a solid or nonvolatile liquid is dissolved in the buffer solution.
You may find it most convenient to prepare a large (500 mL) buffer
solution adjusted to the desired conductivity and pH, and then
dilute sample material with the buffer solution in a standard
sample vial (1.7 mL centrifuge tube).

To slow the growth of contaminants in a buffer solution or sample
solution, refrigerate them when not in use. In addition, use caution when
handling sample vials to avoid transferring contaminants to the vial.
