Processing Euro-Brite Electrodes:

When processing Euro-Brite Electrodes, the current and pressure levels shown in the accompanying table (below), produce the best results. Pressure in the first two stages is, of course, relative to tube length and bombarder power. Always consider tube length as it applies to quality of the finished product.

Excessively long tubes are a trade off. We recommend that you work within tow to eight foot ranges as much as possible. Please follow suggested bombarding and pumping procedures.

Common Applications for Popular Sizes:

ELE30 R/RP 55 (12-mm and 13-mm glass shell diameter)

This small electrode is designed for use with 8, 9, and 10-mm tubing. It may operate on either a 20mA or 30mA transformer. One important factor to remember when working with these smaller diameter tubes, is that the current levels used in processing should be as low as possible to avoid damaging the phosphors. Emitter conversion of this electrode takes place easily with 300mA of current.

ELE50 R/RP 60 (12-mm and 13-mm glass shell diameter)

This electrode, designed for use on 12 and 13-mm diameter tubing, operates well on a 30mA transformer. It tolerates up to 50mA current, however you should never exceed 30mA on 12 or 13-mm diameter tubing. Current levels higher than 30mA on these smaller diameter tubes can be very damaging and produce extremely unpleasant results. This electrode should not be used on any tubing smaller than 12-mm, because of the higher current level of 500mA required for emitter conversion.

ELE45 R/RP 50 and 45 R/RP 65 (15-mm glass shell diameter)

This electrode, designed for use on 15-mm and larger diameters, operates on 30mA transformers. The conversion of emitter coating occurs at 450mA. Since the vast majority of gas discharge tubes are 15-mm, operating on 30mA transformers, this type is a mainstay in most neon shops. Although this electrode tolerates current levels in excess of 30mA for a short period of time, it is not recommended for use with 60mA transformers.

ELE80 R/RP 70 (15-mm glass shell diameter)

This electrode may be used with any tube diameter 15-mm or larger, and operates with current levels of up to 80mA. This electrode is ideal for processing 15-mm clear tubing because it will allow you to heat the tube to higher levels without damaging the electrodes. It is not recommended for use on smaller diameter tubes because the 800mA current level, required to convert the emitter, will damage phosphors in the smaller tube and could elevate the glass temperature too much.

ELE120 R/RP 65 (18-mm glass shell diameter)

This electrode may be used on 20 to 25-mm diameter tubing and will operate well on a 120mA transformer. Conversion of the emitter takes place at 1200mA. This electrode will require a large bombarding transformer to completely convert the emitter. Complete conversion of the emitter coating is critical to produce high quality gas discharge tubing.
