Malvern Instruments NanoSight NS500 Size and Concentration Analyser

This was removed from a university lab where it was surplus to requirements. It is in good cosmetic condition and powers on, we are unable to test it further at our facility. The lab informed us that currently it is operating well, however they were getting an 'autofocus error' when they request the software to auto-focus. Because manual focus is also an option, it wasn't a huge issue. Please note: the software dongle is missing, meaning the included NanoSight software cannot currently be used. Malvern may be able to supply a replacement dongle, but it must be purchased directly by the end user. Includes; 1x NanoSight Software CD NTA 2.1, 1x NanoSight Software CD NTA 2.1 Operating Manual, 1x NanoSight NS500 Operating Manual, 1x NanoSight NS500 Gaskets (pack of 5)
