Thermo Fisher Scientific's Orbitrap Exploris 240 model, constructed from 260 nanoblock pieces. This is a new, unopened item obtained at an exhibition. I am selling it because I have no plans to use it. This is a non-sale item. Perfect for a rare item collection. Thank you for looking. #ThermoFisherScientific #ThermoFisherSientific #nanoblock #nanoblock #block #NotForSale #toy
