Geller has been gone as a supplier since 2013 (most of the web site is
still up as an archive, but he is no longer selling the voltage
"references").
There are a few low-ish cost "references" or "standards" advertised on
ebay. An annotated schematic of one NOT to get (the Calibratory D-105
"2ppm Voltage Reference") can be found here:

Best regards,
