 Notes “This instrument is recently removed from a working environment due to our research interest ... “This instrument is recently removed from a working environment due to our research interest shifting to particles outside the detection range of this instrument (0.2 - 60 µm). Instrument is well maintained. A service engineer installed a new power supply (part B28891) after the 24V DC power for the solenoid valves failed in July 2021, and the issue has not recurred. This sale includes:Multisizer 4e, 2 10-µm aperture tubes (0.2 - 6 µm) (B42812), 1 20-µm aperture tube (0.4 – 12 µm) (A36390), (30-µm aperture featured in data shown in photos was dropped and broke during preparation of the instrument for sale), 3 50-µm aperture tubes (1.0 – 30 µm) (A36392), 3 70-µm aperture tubes (1.4 – 42 µm) (A36393), 1 100-µm aperture tube (2.0 – 60 µm) (A36394), Multisizer software v4.03 installer for Windows on flash drive, Power cord, Ethernet cable.
