Today’s research and biologic production demands on cell and tissue culture assumes no guesswork to confirming viable cell populations. Therefore, both cell concentration and percentage of viable cells must be determined accurately and precisely. The new Vi-CELL Series Cell Viability Analyzers provide an automatic and cost effective means to perform the trypan blue dye exclusion method. This data is essential to the decision making process for basic tissue culture cell passage and maintaining optimum culture conditions in bioreactors. Cell and tissue culture applications in life science research, including recombinant protein and biopharmaceutical production, require the accuracy, precision and automation available only in the Vi-CELL cell viability analyzer.
The Vi-CELL automates the widely accepted trypan blue cell exclusion method. Historically, cell viability determinations were performed manually using a light microscope and hemacytometer. This technique has major shortcomings due to subjective determination of cell count, as well as manual, time consuming steps.
In comparison to the manual technique, the Vi-CELL automatically performs the trypan blue with video imaging of the flow-through cell. Results are obtained in minutes.

N5 Submicron Particle Size Analyzer for Dynamic Light Scattering Accurate Submicron Particle Sizing Using Photon Correlation Spectroscopy (PCS) If particles in the submicron range are part of your production or product development process, measurement and control of particle size is important to you. You need an analyzer that can reliably detect the component populations in your sample every time. Ebay Bid Blocker Freeware Files. The N5 Submicron Particle Size Analyzer uses Photon Correlation Spectroscopy (PCS), which determines particle size by measuring the rate of fluctuations in laser light intensity scattered by particles as they diffuse through a fluid.
The particle size in the powders was analyzed using a particle-size analyzer (LS13 320, Beckman Coulter Inc., USA) that included a laser-induced scattering measurement detector. Electron diffraction patterns and elemental composition were obtained using selective area electron diffraction (SAED) and X-ray electron diffraction spectroscopy.

PCS is the only nondestructive method for measuring particle size down to a few nanometers, and the N5 is the only commercially available PCS analyzer that won’t leave you wondering whether or not you really know what’s in your sample.Only multi-angle PCS analysis can reveal more accurately all the particle populations in your sample.The N5 is the only PCS analyzer that uses six fixed measurement angles. Most PCS analyzers perform measurements at only one angle, typically at 90 degrees. Because submicron particles scatter light in patterns depending on particle size, larger particles may be difficult to detect at 90 degrees if the sample contains a large number of smaller particles. Similarly, any population of particles that scatter weakly at a certain angle may be masked by particles with strong scattering at that angle. For this reason, single or dual angle PCS instruments provide only a partial view of your sample.
Adjustable-angle instruments (goniometers) are prone to inaccuracy, in addition to being cumbersome. Whether you are trying to characterize the results of a process in R&D, or monitoring for contamination on the production line, only the multi-angle N5 can consistently and accurately characterize your sample.
