Envision

“The sensitivity of the optical system allows for much lower laser intensity to be used even for the smallest and dimmest particles, resulting in much improved stability of even photo-sensitive fluorescent labels.​​ Reducing laser intensity for fluorescence-mode NTA measurements means that fluorophores are only minimally bleached. In contrast to other systems where fluorescent particles typically exhibit short lifespans of a few seconds, the Envision consistently allows for prolonged observation of these samples over tens of seconds to minutes. This capability ensures robust and dependable measurement of all fluorescent samples, providing comprehensive data representation.”

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.

By focusing on the collection of statistically significant populations, our workflow enhances reproducibility and repeatability by measuring a greater number of particles under optimal optical conditions. This approach significantly reduces inter-operator and inter-laboratory variability, leveraging increased statistical sampling to deliver stable results. Through consistent sample volumes, optimized optics for enhanced accuracy, and minimized user-dependent variables, we achieve improved repeatability in both size and concentration measurements.

By expanding the lower limit while maintaining the capability to measure larger particles, the technique effectively broadens the dynamic range of the system. The robust construction of the optical system delivers clear and precise imaging, facilitating optimal conditions for a diverse range of sample types without compromise. Furthermore, a meticulously engineered vibration isolation system mitigates environmental influences on results, particularly in larger size ranges. This setup enables reliable measurement of larger samples made from various materials, with conditions tailored for each specific sample.

Rather than optimizing design solely based on cost, the Envision was engineered with a primary focus on performance and reliability. Components were meticulously selected based on rigorous specifications and design criteria, prioritizing collaboration with top-tier vendors renowned for superior quality. Key design objectives encompassed durable components, long-term reliability, and minimized servicing costs. This commitment to long-term value underpins our confidence in offering a three-year warranty on laser modules and a two-year warranty on all other components.
