Cleaners to Prepare for Sterilization
Q. What products prepare instruments for sterilization?
A. Use a proper cleaner prior to sterilization. Alconox and Liquinox instrument cleaners are effective and economical manual, ultrasonic or soak cleaners.
Citranox Corrosion for Photovoltaic Application
Q. We use Citranox for cleaning glass coated with tin oxide. We use the cleaned glass to deposit thin film CdS/CdTe photovoltaic devices. We use your citranox detergent and use a stainless steel ultrasonic cleaner. Is there a concern that the citranox could corrode stainless and deposit metallic ions on the glass surface? Which can be detrimental to the semiconductor films of the photovoltaic devices? Should we use a PTFE ultrasonic cleaner?
Using a Miele Washer
Q. I was curious if Solujet and Liquinox are interchangeable? We are a medical device company that currently uses Liquinox to wash glassware by hand, but recently got a Miele glassware washer and want to use an Alconox product in it.
A. Solujet will give comparable cleaning performance in a Miele washer to manual cleaning with Liquinox.
Using a Conductivity Controller in a Washer
Q. How does a conductivity controller regulate a dosing pump in a machine washer?
A. A conductivity probe would need to be set up in the sump of a machine washer. The conductivity recorded is sent to the conductivity controller that regulates the pump (usually a peristaltic pump) that dispenses the detergent into the sump. The pump dispenses until the correct conductivity is reached for the desired concentration. Typically a concentration of 0.5% or 0.1% detergent is desired.
Advantages of Properly Cleaned Glass Substrates
Q. I have previously worked on CdTe solar cells in academia and DSC in industry and currently work with industry on collaborative R&D projects across materials science. I would like further information on the advantages of properly cleaned/prepared glass substrates and it’s effects of module/cell performance.
