Manufacturing Cleaning – Vacuum Tubes
Q. We have an other department that makes a vacuum tube that is nearly identical to ours and they have a much better yield. They use Liquinox for their cleaning agent. I would like to talk to one of your engineers regarding their view of our present cleaning method (Sodium Hydroxide, Muriatic Acid, DI water, Methanol) vs. Liquinox. I have no historical information as to why we use the mentioned chemicals. The items that are cleaned are: tungsten plates, kovar pins and glass.

Cleaning Titanium with Neutral Detergent
Q. We cannot determine residues of detergent and we cannot validate the detergent. We are choosing a new detergent that cleans protein and this detergent must be neutral to titanium. We don’t want corosion trouble. The titanium equipment’s manufacturer recommends to use neutral detergents.
A. While much titanium equipment can be cleaned with non-neutral detergents, if the specific manufacturer recommends a neutral range detergent we can certainly suggest one. We recommend cleaning with a 1% Liquinox solution which has a neutral range pH of 8.5.
