Astro Pak has cleaned hardware and components for almost every cleanliness critical industry and application since 1959. Our studies have shown that the chrome to iron ratios achieved by our Ultra Pass® passivation far exceeds ASME BPE recommended minimums and meets or exceeds the requirements of many industries including pharmaceutical, biotechnology, space and semiconductor. Some of the world’s most prestigious institutions including JPL, Lawrence Livermore National Laboratory, MIT, and Cal-Tech have sought guidance and consultation from our subject matter experts. For cleanliness critical components our Cleanroom Services locations are ITAR compliant and feature ISO 14644-1 certified Class 5, 6, or 7 cleanrooms and labs of varying sizes and capabilities. We also house an extensive library of approved procedures and meet the standards and specifications set forth by both industry regulatory bodies and private organizations. Our Cleanroom Services locations maintain AS9100 certified Quality Management Systems.
