Beckman Coulter Vi-Cell XR Cell Viability Analyzer

Beckman Coulter Vi-Cell XR Cell Viability Analyzer

Cambridge Scientific ID #'s: 14527, 20807, 20120

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

Waters ZQ 2000 LC/MS System

Waters ZQ 2000 LC/MS System

Cambridge ID #: 16408

Includes:

  • Waters ZQ Single Quadrupole Detector
  • Computer w/ MassLynx software
  • Monitor and Cables
  • Manuals

 

The Micromass-ZQ 2000 (Mass Selective Detector) is a robust single quadrupole mass spectrometer, offering characteristic performance for laboratories that require nominal mass resolution for mass confirmation applications.  This system has a mass range (amu) up to 2000 daltons.  Easily qualify and quantify small molecules in a flash with the highly sensitive system.  Both inlet probes are quickly and easily interchangeable without breaking vacuum.  Flow rates allowed are 5-1000 µl/min (ESI) and 200-2000 µl/min (APCI).

 

Specifications:

  • Air Cooled System
  • Mass Range 2000amu
  • ZSpray dual orthogonal sampling interface provides unsurpassed sensitivity.
  • Vertically mounted liquid inlet probes to minimize tube length and peak dispersion
  • Software-controlled, intergrated syringe pump for easy calibration, tuning and sample infusion
  • Digital control of source gas flow rates
  • Software controlled divert valve/manual injection valve
  • Differentially pumped vacuum system featuring singular air-cooled, split flow turbomolecular pump technology
  • Sensiticity: 1 pg Reserpine
  • Mass Range: 2 – 2000
