Beckman Coulter Vi-Cell XR Cell Viability Analyzer

Beckman Coulter Vi-Cell XR Cell Viability Analyzer

Cambridge Scientific ID #'s: 14527, 24119, 20807, 23189

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.

Includes:

  • Computer w/ Software
  • Monitor
  • Manuals

Product Features:

  • Automation of the standard trypan blue assay
  • % Viability
  • Total cell concentration
  • Total viable cell concentration
  • Mean cell size
  • Real time cellular images
  • Bioprocess monitoring

Beckman Coulter Z2 Particle Counter

Beckman Coulter Z2 Particle Counter

Cambridge ID #: 12488

The Z2 COULTER COUNTER is the latest addition to the Z Series COULTER COUNTER. In addition to reporting both count and concentration results, the Z2 adds the ability to provide size distribution of the cell population. The Z2, like the Z1, uses the Coulter Principle (Electrical Sensing Zone Method) of counting and sizing of cells. This technique provides accuracy, speed, versatility and reproducibility. The Z2 displays the entire size distribution graph, or the size statistics and counts between user selectable areas of the graph. In addition, this instrument displays the cumulative count and the cumulative number % above and below a size determined by the cursor positioned on the graph. Additional Benefit, Averaging Data The Z2 has the ability to average counts and channelized data from a series of up to 10 consecutive analyses. The more cells counted and sized the greater the statistical confidence in the result and the smoother the shape of the averaged size distribution.

 

Includes:

  • Control Panel/Keyboard
  • 100 micron aperture
  • All Necessary Cords, Cables
  • Manual

 

Performance Specifications

  • Mercury Free
  • Sample result averaging
  • Size distribution graph and tabular data
  • Small Footprint
  • One-Button Calibration
  • User test functions built-in
  • Storage of up to 5 instrument settings for different cell lines
  • Technology defined by the International Standard (ISO 13319:2000: Determination of particle size distributions -- Electrical sensing zone method)
