Beckman Coulter VI Cell XR Cell Viability Analyzer****This instrument has been tested and is working to specifications. Buyer should expect a working machine with a 30-day warranty. Everything pictured included. See photos for details.(Please be advised that any warranty/guarantee/return policy provided from the seller is between the buyer and the seller only. Bid on Equipment is not and cannot be held responsible in any way. Please reference our Terms and Conditions for further information.)The Vi-CELL Cell Viability Analyzer provides an automatic means to perform the Trypan Blue Dye Exclusion method, allowing users to load up to 10 samples at once for easy and automated cell analysis. Vi-CELL software offers pre-programmed and customizable analysis options for consistent and accurate analysis of simple cell systems or your own cell line.Powerful, Flexible SoftwareBioprocess tracking, auto-sampler queue & control monitoring featuresReal-time cellular imaging for data parameters not available with standard aperture cell counting methodsProvides results for percent viability, total cell & viable cell concentration and mean cell sizeOperation12-position auto sampler for walk-away sample analysisSamples within 50 x 103to 1 x 107cells/mL range require no dilutionCustomizable cell types for analyzing diverse cell speciesBioprocessing ApplicationsKey cell culture parameters to help you optimize and monitor the bioprocessResults can be viewed easily on the screen or exported for off-line analysisThrough integration partners we offer optional automated online sample introduction for real-time cell analysis for improved bioprocess monitoring and controlCompliance and Validation21 CFR Part 11 enabled with audit trail, electronic signature capability, secure sign-on, multiple user level permissions & administrative configuration toolsIQ/OQSystem Specifications:Data Acquisition:Operating principle: analysis of video imagesSample type: spatial dataCell size range: 3 microns to 70 micronsNOTE Although the size range for system performance is 3 microns to 70 microns, the system is capable of detecting particles down to 2 microns.Analysis rate: up to 50 Images in 2.5 minutesDigitizing resolution: 1.45 mega-pixelsCell Viability/Concentration/Cell CountConcentration Range: 0.5 x 105 to 10 x 106 Cells/mLViability Range: 0 to 100%Mean Recovery Value of 20 replicates of Concentration Control on Vi-CELL XR compared to the lot assay value used are 6%.NOTE The results for samples at the low end of the concentration range will not be as statistically accurate due to the low number of measured cells. The accuracy at the high end of the concentration range is affected by the difficulty of declustering groups of cells particularly if the cells are large. The sample should be diluted to bring its concentration into range or to improve the accuracy of the resultsPower 50 watts (65 watts max.)Temperature 10 to 40C (50 to 104F)Fuses 1 - 120 V 1 A SLO-BLO, 2 - 240 V 2.5 A SLO-BLOAdditional Prep Fees May Apply
