This NEW Leybold TURBOLAB 250i benchtop vacuum pumping system comes with an CF100 CF 6 in. Inlet Flange and is a Full-Featured system at a basic system cost (WITH NO ROUGHING PUMP). The TURBOLAB 250i benchtop systems include a TURBOVAC 250i turbo pump, the TurboLab Pump System and frequency converter. The TURBOVACs are turbomolecular pumps with lifetime lubricated ceramic ball bearings. A built-in thermal switch switches off the TURBOVAC if the permissible temperature is exceeded. The frequency converter is integrated into the TURBOVAC and is supplied with 24 VDC and controlled via RS 485 interface by the TURBOLAB. They also are designed to mount further components such as Leybold vacuum gauges: TTR 101, TTR 91, PTR 91, TTR 101N, TTR 91N, PTR 91N. Two vacuum gauges can be operated simultaneously. They operate on 1-Phase, 100 or 240V power (correct voltage must be set on the unit).

The overall pumping speed of the Leybold TURBOLAB 250i Vacuum Pumping system for nitrogen is 65 liters/sec and they reach an ultimate pressure rating of 1x10^-7 Torr (1x10^-7 mBar). These high vacuum turbomolecular pump systems are fully assembled, ready-to-operate (WITH YOUR ROUGHING PUMP) and are designed as bench top units. The integrated 250i turbo pump has a built-in frequency converter, includes air cooling, grease lifetime lubricated ceramic ball bearings, a high vacuum CF100 CF 6 in. intake connection and includes a splinter guard.

They have appealing features such as being absolutely oil-free, having a low ultimate pressure (free of hydrocarbons), compact units with simple operation and a high reliability level, maintenance free design, air cooling and installation of standard components in the encasement. Typical applications for the Leybold TURBOLAB 250i Vacuum Pumping System include, but are not limited to: Spectroscopy, Tube manufacturing, Laboratory pumping systems, Beam Guidance systems, Micro Balances, Surface Physics and Sputtering or Evaporating Systems. The system MUST NOT be used for pumping flammable or combustible gases and vapors, radioactive and toxic gases and vapors, pyrophrous substances and oxygen applications that exceeds the concentration in the atmosphere (.21%).
