Varian TV-301

This is a used Varian TV-301 turbomolecular pump, a compact high vacuum pump built to deliver clean vacuum performance in analytical instrumentation and research vacuum systems. Like other turbo pumps in the Varian line, it operates using a high speed rotor to move gas molecules through the pump body, generating the high vacuum conditions many scientific instruments depend on for accurate operation. The TV-301 was commonly deployed in smaller vacuum chambers and compact instrument platforms where space was limited but high vacuum performance was still required, including mass spectrometry systems, thin film deposition tools, and various surface science instruments. It typically worked in conjunction with a mechanical backing pump to achieve full operational vacuum range. Supplied here as a used unit in as is condition, this pump is a good fit for labs maintaining legacy Varian vacuum equipment or technicians seeking a working replacement to avoid downtime on instruments that rely on this exact pump model.
