High Pressure homogenizer for nanoparticle preparation
"The Cary Eclipse Spectrophotometer uses a Xenon flash lamp for superior sensitivity, high signal-to-noise, and fast kinetics. It measures the emission of light from samples in four modes. Using Xenon lamp technology, it captures a data point every 12.5 ms and scans at 24,000 nm/min without peak shifts. The Cary Eclipse is the only spectrophotometer with room light immunity. With an optional microplate reader, it offers full wavelength scanning of 384 samples. "
"The S-3400N is a powerful, yet user-friendly SEM with sophisticated electron optical and automated functions, including Auto Beam Setting with Auto Axial Alignment. These are complemented by simple switching between variable pressure, high-vacuum and low-voltage modes with a single button press The novel "Quad-Bias" facility offers significantly higher probe currents for superior imaging even at low accelerating voltages, below 3 kV. This protects samples from beam damage and guarantees detailed surface imaging. Optimized detector technology such as the patented Environmental Secondary Electron Detector (ESED II) and innovative 4+1-Segment-BSE-detector provide maximum information from every sample. Variable chamber pressure allows charge up-free observation of any sample without special preparation techniques such as coating. The analytical specimen chamber design has optimum geometry for simultaneous accommodation of EDS, WDS and EBSD. The S-3400N features a 5-axis motorized stage with high tilt (-20° to +90°) which can accommodate samples up to 200 mm in diameter and up to 80mm high."
