Higher performance derived from an advanced optical system provides lower limit of detection, enhanced fluorescence performance and efficiency, a clear image to lessen operator dependence, and superior reproducibility. Greater ease of use comes from understanding user needs, including a built-in sample pump, sealed sample cell, bubble-free fluid transfer, and a stable optical system. The Envision was engineered to address the frustrations of researchers limited by the first generations of NTA instruments. By applying proven science and dedicated development, every aspect of the system has been improved so the analytical capabilities and the user experience are truly a generation ahead..
Advanced Optical Design
The Envision optical system provides a high signal to noise image, allowing for more accurate and precise measurements of a wide range of sample types without background optical interference. This sharply focused image of even the smallest particles provides enhanced sensitivity to extend the measurement range of the NTA technique to smaller sizes than previously possible.
Breakthrough lower limit of detection
Quality image allows unparalleled performance. The high signal to noise ratio allows measurement of smaller sized particles than previously possible with NTA. The lower size limit depends on material refractive index, but the low noise image allows tracking of even weakly scattering particles.
Robust, Reproducible, and Repeatable
With a workflow built around collecting statistically significant populations, reproducibility and repeatability is enhanced with measuring more particles under ideal optical conditions. Inter-operator and inter-laboratory variability is greatly reduced as a result of increased statistics due to measuring more particles than other instruments, providing stable results from a consistent sample volume, optimized optics for better accuracy, and limited user dependent variables. This improves repeatability of both size and concentration measurements.
Ease of Use
Software built around user workflow and automating the user dependent variables through the use of advanced technology means sample operation is a breeze, thus removing operator variables and improving throughput and repeatability even further. The built-in sample pump ensures consistent, bubble-free sample loading, repeatable flow speeds, and easy cleaning cycles through a fully automated SOP. The sealed sample cell is proven bubble-free and easily replaceable when needed for maximum up-time.
Quality parts and robust design for confident reliability
Instead of building down to a cost target, the Envision was designed for performance and reliability. Components were selected based on specification and design before considering cost, in collaboration with highest quality vendors available. Design targets included robust components, long term reliability, and minimal cost of servicing. This focus on the long term relationship gives us the confidence to offer a three-year warranty on laser modules and a two-year warranty on all other components.
