VACUUM INSTRUMENTS CORPORATION, LLC

Vacuum Instruments Corporation, LLC specializes in the repair, maintenance, and procurement of precision industrial and scientific instrumentation, with deep expertise in helium leak detection systems and high-vacuum equipment. The company delivers onsite service visits, calibration, and component replacement for mission-critical machinery used in defense and aerospace environments, including power supplies, measurement devices, and vacuum-based test systems. Their technical proficiency centers on maintaining the integrity of sensitive control and sensing instrumentation, ensuring operational reliability in demanding environments where contamination control and precision measurement are non-negotiable. A key differentiator is their ability to source, integrate, and service specialized leak detection hardware such as the MS-40 GT, demonstrating direct experience with industry-specific tools critical for aerospace and defense applications. The contractor maintains a consistent relationship with the Department of Defense and the National Aeronautics and Space Administration, providing both routine maintenance and targeted procurement of high-reliability instrumentation. For DoD, they support communication and industrial equipment upkeep through responsive onsite service, while NASA relies on them for the acquisition and integration of advanced leak detection systems essential for spacecraft and propulsion system validation. Their primary focus lies in NAICS 811310, which encompasses the repair and maintenance of non-automotive, non-electronic industrial machinery—particularly vacuum and pressure-sensitive systems—and NAICS 334519, involving the manufacturing and servicing of specialized measuring and controlling devices. This positions them as a niche provider in the scientific instrumentation supply chain, serving high-stakes technical environments requiring precision and regulatory compliance. As a small business structured as a 2L entity based in Ronkonkoma, New York, Vacuum Instruments Corporation, LLC operates without federal certifications but maintains a focused presence in the defense and aerospace federal contracting market, delivering tailored technical support where standard commercial vendors lack the required specificity or access.
