Pine Research Instrumentation (Raleigh, NC) is a spin-off company of Pine Instrument Company (Grove City, PA). These two related companies have used two different color coding standards for electrochemical equipment. Since 2007, Pine Research Instrumentation has used the “PRI Standard”, but before 2007, the older “PIC Standard” was used. Both standards are described in detail in this article.

"PRI Standard" Color Scheme (after 2007)

Pine potentiostats and rotators designed after the year 2007 utilize the following color scheme:


Examples of products which use this color scheme include the WaveNow/WaveNano Cell Cable and the Mini-USB Cell Cable sold with Pine's Compact Voltammetry Cell.


"PIC Standard" Color Scheme (before 2007)

The older model analog bipotentiostats offered by Pine Instrument Company (part numbers AFRDE3, AFRDE4, AFRDE5, and AFCBP1) used the following color scheme. Note that on the AFCBP1 the electrode connections are located along the right side of the front panel. On the earlier models (AFRDE3, AFRDE4, and AFRDE5), the electrode connections were located along the bottom-left of the front panel.


All of the traditional analog bipotentiostats offered by Pine Instrument Company featured a built-in, true analog sweep generator. Additional output signals on the front panels of these instruments permitted the sweep generator and/or the current and voltage signals from either electrode to be used to drive a classic XY pen plotter. These connections appear along the bottom of the front panel of these instruments.

The older model MSR rotators (part numbers AFMSRX and AFMSRXE) used the following color scheme.
