bivac

BIVAC is a line of compact, modular vacuum devices developed for laboratory and industrial use, designed to provide efficient degassing and gas removal in a wide range of processes. The name is an abbreviation of “Bi‑Integrated Vacuum Apparatus,” reflecting the system’s dual capability to create both positive and negative pressure environments within a single unit. Each BIVAC unit typically consists of a vacuum pump, a pressure‑sensing module, a programmable controller, and a set of interchangeable ports and seals that allow users to connect to glassware, tubing, or custom assemblies. The controller software enables precise regulation of pressure levels and cycling patterns, and many models support remote monitoring via Ethernet or Bluetooth interfaces.

BIVAC units are commonly employed in biochemical research for preparing samples before chromatography, in materials science for removing adsorbed gases from polymer films, and in industrial settings for degassing fuels, oils, and other liquids. The devices are engineered to maintain high vacuum levels—typically below 10 millitorr—while simultaneously offering rapid evacuation times of less than two minutes for standard 120‑ml glassware. In addition, BIVAC’s multiple‑stage pressure modes support both quick purge and gentle conditioning phases, making them suitable for processes that require minimal disturbance of temperature‑sensitive samples.

Several manufacturers produce BIVAC‑type systems, with key players including Bivac Instruments Ltd., a German company established in 1998, and the more recent entrant, DegazTech Inc. from the United States. These firms emphasize the environmental benefits of their units by incorporating energy‑efficient brushless motors and smart waste‑gas handling that reduces volatile organic compound emissions. The market has seen growth driven by stricter EU and U.S. regulations on atmospheric release of hazardous substances, as well as increased demand for high‑purity analytical standards in pharmaceuticals.

Looking forward, developments in portable BIVAC micro‑systems promise on‑site degassing for field research and emergency response scenarios. Integration with Internet‑of‑Things platforms is also anticipated to streamline data collection for quality control and regulatory compliance.
