The Zeiss Elyra Superresolution Microscope is a developmental superresolution microscope with capabilities to push imaging past the classic diffraction limit. Typically visible light microscopes cannot achieve spatial resolution of greater than 200-250 nanometers. This system has two different imaging modalities to push this limit as low as 20 nanometers.
Lighsheet microscopy is a fluorescence-based imaging technique that is growing in popularity. It outperforms other techniques in its ability to rapidly capture large optically sectioned three dimensional datasets, whilst keeping photo-toxicity and bleaching to a minimum. It therefore lends itself well to imaging samples larger than those typically attempted by conventional fluorescence microscopy such as tissues, whole organs and even embryo development.
The Zeiss LSM 780 is a high-sensitivity laser scanning confocal microscope. Unlike most standard confocal systems this instrument comes equipped with a GaAsP photodetector. This detector in addition to boasting a quantum efficiency of 45% (in comparison to 25% for standard PMTs), it can also be used as a single-point detector or as a 32-channel detector array facilitating spectral measurements. It can also be switched into a single-photon counting mode providing great signal to noise for such techniques as FCS and RICS.
The Zeiss LSM 880 is an inverted laser scanning confocal microscope equipped with high quantum efficiency GaAsP detector and 2 multialkali PMTs, which can be used as single point detectors or combined for 34 channel spectral imaging. In addition, the Airyscan module can deliver images with 1.7 x improved resolution (140nm axially, 400 nm laterally) and 4-8 x greater signal-to-noise ratio, at the highest speed of any linear scanning confocal system. BiG.2 Type A (2x GaAsP detectors) non-descanned detectors for the multi-photon laser can be used for imaging thick specimens, with deeper penetration and decreased phototoxicity compared to single photon lasers. The Picoquant system utilises the multi-photon laser to perform Fluorescence Lifetime Imaging (FLIM), Fluorescence Correlation Spectroscopy (FCS), Forster Resonance Energy Transfer (FRET). The Zeiss 880 is also equipped with polarisers for anisotropy measurements.
The Zetasizer Nano ZS is a high performance two angle particle and molecular size analyser for the enhanced detection of aggregates and measurement of small or dilute samples, and samples at very low or high concentration using dynamic light scattering with ‘NIBS’ optics. The ZSP also incorporates a zeta potential analyzer that uses electrophoretic light scattering for particles, molecules and surfaces, and a molecular weight analyzer using static light scattering.
