Cleaning Carbon Deposit Swirls On Alumina Parts

Q. Our parts, made of 99.5% alumina, have carbon deposits that show up after our brazing process. We do not use a flux for our ceramic parts; we high-temp fire a moly/manganese painted paste onto the ceramic. The part is then sent out for nickel plating to prevent corrosion of the moly manganese metallization areas. The next step is our brazing.

We are not seeing any spots on the parts before brazing, but as we continue through 5 brazing cycles and braze in a hydrogen/Nitrogen furnace with the cusil braze rings, we see black spots forming that show up as high-carbon deposits with the SEM data…

Minimum Detergent Concentration?

My question is related to a minimum detergent concentration.  We manually wash labware of all sizes in 0.3% Liquinox solution. We also pre-wash or pre-rinse the labware and control our parts load.  We rarely have failures. We want to change our protocol to extend the wash water use for one day instead of based on a numerical parts load.  Do you think a 0.3% Liquinox concentration is sufficient detergent capacity to go an entire day?

Citrajet and Hard Water

I work in a lab here in London, and we are washing lab glassware (molecular biology/bacteria) with a standard home dishwasher. We do not have access to distilled water for rinsing, and our water is very hard. Will Citrajet be okay under those conditions? Also, do you have a distributor for Citrajet in the UK?

Choosing Ideal Detergent for Cleaning Metal Parts

Q. We are currently writing a protocol for conducting a process validation activity for our cleaning procedures for metal parts after our machining manufacturing process. What are the differences between cleaning effectiveness of Alconox detergent for cleaning various metallic surfaces such as stainless steel, titanium and cobalt chrome? Also, does Alconox detergent effectiveness change based on contamination characteristics, surface geometry or any other factors?

Medical Device Cleaning: Soft Acrylic Intraocular Lenses (IOLs)

Q: We are cleaning both hydrophilic and hydrophobic acrylic polymers. The cleaning process we use is mostly manual, involves no extended soaking, rather short contact with rubbing, and/or usage in an ultrasonic bath. Which of your products — Alconox, Tergazyme or Liquinox — would be most suitable for the cleaning of soft acrylic intraocular lenses (IOLs)?
