Used VARIAN TV 70 #9223282 for sale

VARIAN TV 70 is an all-metal, high vacuum turbomolecular pump designed for all types of ultra high vacuum systems. This pumping equipment is ideal for use in scientific research, analytical equipment, and semiconductor manufacturing. TV 70 is capable of reaching a compression ratio of up to 11,000,000 to 1, which translates to a maximum achievable base pressure of 1 x 10-9 mbar and a pumping speed of up to 70 l/s depending on the gas composition. This powerful system is capable of evacuating from a wide array of ultra high vacuum systems, including but not limited to environmental SEMs, scanning tunneling microscopes, ion beam sources, plasma etching, and many other vacuum applications. This turbo pump makes use of a high-performance, maintenance-free, and durable motor and high-efficiency curved-bladed impellers. It is capable of operating at a wide temperature range and is equipped with an integrated mechanical pump (Roots type) used for roughing down or pre-pumping. Additionally, it has a bypass valve set at 20 Torrs and a gas ballast function for pumping condensable or non-condensable gases. The pump also has adjustable inlet and exhaust flanges as standard features. These features allow the user to choose a configuration that suits their specific vacuum requirements. VARIAN TV 70 is also equipped with a monitor that shows the total pressure of the vacuum unit, and the pressure in the connected mechanical pump. Additionally, this monitor supports the measurement of the speed and operating temperature of the turbo pump. TV 70's monitor also serves as a warning machine, alerting the user to any potential problems that may arise with the pump or vacuum tool. VARIAN TV 70 turbo pump is an efficient, durable, and cost-effective pumping asset for ultra high vacuum applications. The turbo pump is designed to reduce maintenance costs, while providing long lasting, reliable performance for many years of reliable service. This pump is an excellent choice for use in industrial, scientific, and analytical environments.
