Case Study: Vapor Degreaser Using 3M Novec Solvent For Medical Device Instruments
A Minneapolis, MN based medical device manufacturer of surgical instruments parts has very small passage ways which are extrude honed with abrasive media, mineral oil and also Swiss machines tight tolerance profiles. The low surface tension of 3M Novec 72DA engineered fluid solvent used in a vapor degreaser allows for cleaning these sensitive parts of all the media and oils without any non-volatile residues.
Machine shops often need to wash parts that come out of machining centers with true oils (petroleum based) as well as water soluble coolants. In this application, the customer had a long list of true oils they needed to remove from precision machined parts.
Spring Cleaning: Passivation specification and process review
Many companies are trying to move toward more environmentally friendly chemistries including for stainless steel passivation processes. Nitric acid has long time been used for passivation but employee exposure, handling and environmental disposal issues have always been a challenge. With recent advancements in biocides for citric acid, citric acid use for passivation has grown significantly.
Here are a couple helpful links:

Spring Cleaning: Clean up the plant floor by moving the process into cells
Automated Precision Aqueous Cleaning in a Lean Cellular Manufacturing Design– This system a perfect solution for your cellular cleaning needs; the single basket system that takes up less than 20 square feet of plant floor space. These systems are build for lean manufacturing environments where manufacturing plant floor space is a premium (cleanroom, dry room, etc) but are built to clean even your toughest applications.
Spring Cleaning: Clean up hazardous solvents like nPB and move to aqueous cleaning
- Much safer for employee exposure
- Significantly lower environmental impact including zero ozone depletion
- Zero discharge with regenerative deionized water system
- Cleans their parts better than their old solvent process.
