Bath Maintenance & Preparation
- The platinum content of the bath can be reduced to half the initial concentration without changingthe current yield, but should preferably be replenished after 30% platinum has been removed. Platinum DNS bath is supplemented with Platinum DNS Bath R (50 g Pt/l).
For every 1 g of platinum removed, 20 ml of Platinum DNS Bath R is added to the bath. - The delivered stock concentrate is stirred into approximately three times the amount of deionized water and then topped up to bath volume.
- Platinum DNA bath is supplied as a concentrate with 50 g Pt/l. Other concentrations available on request.
