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
Several manufacturers produce BIVAC‑type systems, with key players including Bivac Instruments Ltd., a German company established
Looking forward, developments in portable BIVAC micro‑systems promise on‑site degassing for field research and emergency response
