Pilkingtons Research Centre,Lathom

Date: 6 September 2003

World renowned glass manufacturers Pilkington has recently installed a multi-step aqueous wash system for precision cleaning of glass samples at their Lancashire based Research and Development facility.

Supplied by Standard Industrial Systems and manufactured by Idea Machine of Finland, the application demanded cleanliness of the highest order before processing in a new
state-of-the art coating installation.


Cleanliness of the washed samples is gauged by measuring the contact angle formed on the glass surface by a sample of pure water injected upon it.

The complex process includes the use of a high quality pure water (1mS/cm) throughout the various stages beginning with an alkaline (Ecospray 5275) followed by an intermediate rinse. A further acid wash is followed by successive rinses and a hot drying facility, all stages being completed within a single chamber without operator intervention after the initial loading. Cross contamination of the various stage fluids has been eliminated by a unique process of counter refills and the continuous automatic dosing of the selected chemical constituents. Both acid and alkaline fluids are combined to form a neutral fluid for disposal, again achieved in-process without operator involvement.
