Pair of National Spectroscopic Graphite Electrods in Original Wooden Box

Description

This auction is for a pair of new old stock 1/2" x 12" special graphite spectroscopic electrodes by National Carbon in original vintage wooden box as shown. I got these at a lab I worked at in the 1980s, and they were probably old then. The ananlysis sheet is enclosed, and even if you did not want to use it for a spectrograph, the boxes themselves make great display pieces.

Due to too many requests by overseas customers, I have to state in the USA it is illegal to falsify the value on Customs forms, as well as being against eBay rules. Do not buy this item and then ask us to falsify the forms. We always declare the sales price, as required by law. If you have asked any seller to falsify the forms in the past, ask yourself this question... Why would you want to buy from a company that demonstrates it is dishonest?
