Our tank is an ideal alternative to the horizontal bath-style trays commonly used in the etching studio.  It's design advantages are immediately apparent.  As compared to a typical acid tray, the Vertical Etching Tank uses 80% less studio space, and has 95% less of the exposed area for evaporation.
Even full, our tank can be safely moved around the studio.  By comparison, bath-style trays are nearly impossible to empty or move without significant spillage.
In 1995 we designed the first rotationally molded, seamless Vertical Etching Tank. It is made from 1/4 inch-thick, polyethylene and is unbreakable and leakproof.  

Its design features include:

• An extended drip ledge, which makes removing plates from the tank safer and mess-free.
• A snap-on, form fitting lid to inhibit evaporation
• Large capacity which allows two full 18"x24" plates (or many smaller plates) to be etched simultaneously.
• The vertical design which not only saves space and reduces evaporation, but encourages the use of the safest, longest lasting, and most precise etchant--ferric chloride.
• A separate stand that is 20" long, 9" wide, and 12" high which provides exceptional stability.
• Compatibility with all commonly used etchants.

 And all of this actually costs less than a conventional acid tray of comparable capacity.
