Tattoo Cleaning – Workstation Setup

12 August 2015

Did you know? If It’s Not Clean, You Can’t Sterilize. There’s a lot that goes into good workstation prep for tattoo artists, but before you stock the area, you need to sterilize.

Cleaning Scale & Spots off Depyrogenated Glass Vials

03 August 2015

Q. We see white water spots on cleaned and depyrogenated vials. Looks to be scale from the washer. Do you have a recommended cleaning agent for vial washing? I am told that use of detergents is not an industry norm. We also have baked on process fluids (oils) and would like to know if it is an industry norm to use detergents to remove such substances from glass vials used for injectable drugs. Can you provide me any literature on the subject? A. In automated washer cleaning, it is possible to get scale buildups of metal hydroxides, oxides and carbonates. To remove this scale ...

Wet Hi Pot Test for Photovoltaic Cleaning

30 July 2015

Q. We manufacture solar modules for building components. During the manufacturing process we are required to perform a "Wet Hi Pot Test." The modules are immersed in a solution and tested. The manufacturer of the test equipment said that some of his customers are using the Liquinox® detergent in a 300 to 1 ratio for the solution. Would this give us the required: 0.03 N/m surface tension 35 ohms/m resistance? Any help would be greatly appreciated.

Assistance Developing Photovoltaic Cleaning Process

16 July 2015

Q: We are looking to hire someone to design and implement a turnkey cleaning process for our Photovoltaic manufacturing application. Do you provide this service? A: Yes. We do this type of work often. With increased governmental commitments to support renewable energy initiatives, winners and losers in solar module fabrication will be determined more quickly and by a variety of factors. One factor will be the elimination of defects to increase yields in the manufacturing process. Critical cleaning of substrates and superstrates is an essential component in achieving an optimal solar module fabrication process which reduces the cost per watt.
