04 Feb 3 ZetaView® Models in 8 Years. How Are They Different?
ZetaView® lets researchers quickly carry out multi-parameter Nanoparticle Tracking Analysis (NTA) without costly calibration procedures or high cost consumables. There are currently three ZetaView® models to choose from.
ZetaView® models available
ZetaView® BASIC NTA PMX-120 was the first model released by Particle Metrix. It only has one laser and is the platform on which the other two models are built. | ZetaView® TWIN NTA PMX-220 is the twin-laser model. It was released after the basic model and gives users a choice of two lasers to use for fluorescent labelling and excitations. | ZetaView® QUATT NTA PMX-420 is the most recently released ZetaView® instrument. This product gives users a choice of four lasers to use for fluorescent labelling and excitations. |
Regardless of the ZetaView® model you choose, some features are guaranteed

Why go for a ZetaView® model with more lasers?
Choose a product with more lasers for enhanced fluorescence measurement capability! Using 2 or 4 fluorophores on the same sample lets you identify 2 or 4 different sub-populations.
