Standard Replacement Quartz Crystals for Film Thickness Monitoring
Colnatec manufactures and stocks replacement quartz crystals for most commercially available fi lm thickness monitors. These include 6 MHz, 14mm diameter crystals (for Inficon™, Sycon™, Sigma™ Instruments and Maxtek™ instruments), 5 MHz, 14mm diameter crystals (for Balzers™ instruments), 5 MHz, 12.5mm diameter crystals (for Ulvac and Sloan instruments), and the new 8mm diameter 5 or 6 MHz crystals for our revolutionary 24-crystal sensor head, Infi nity™. We off er the standard electrode coatings as well: gold/chromium, silver/chromium and aluminum (or “alloy”).
As always, we off er a 100% money back, no questions asked guarantee. When you purchase Colnatec Quartz Crystals, you can be certain that you’re getting the highest quality products at the best possible prices with the confidence and security of our rock solid guarantee.
We package all our quartz crystals in a clean room compatible container which holds 10 crystals. Careful attention to the design ensures that the center of the crystal, where the actual measurement occurs (within a radius of 3 mm from the center), is not touched or contaminated by the plastic. We use pharmaceutical grade PETG plastic for the top, and hand cleaned polystyrene for the base. This diff erence in plastics is needed due to the buildup of static charge between two pieces of PETG. Some manufacturers use anti-static PETG, but this contains a polymer agent that will eventually leach onto the crystal surface.
Believe it or not, all monitor crystals are not the same. From surface finish to the rate at which you put on the adhesion layer, there are subtle di fferences in crystals from di fferent manufacturers. Sometimes though, there are BIG diff erences in manufacturers and that can cost you dearly in the long run.
