Both may appear to be identical, but the part on the left contains over 50 colony forming
units (CFU) of microbial bacteria, whereas the part on the right contains less than 1 CFU.
That’s because the part on the right was created in our 4,000 square foot, ISO 8 certified
cleanroom and passed through a strict quality inspection. So the difference is
clear — for cleanroom manufactured parts, choose PTI Engineered Plastics.
