Description

 

The Beckman Coulter Z2 allows users to count cells or particles. It is a dual threshold cell counter with channelyzer and computer interface capabilities. It uses the Electrical Zone Method, aka the Coulter Principal, which is the accepted “reference method” in the analysis of particle size in addition to a recommended limit test. The EZM for short counts and sizes based on changes in electrical resistance produced by cells that are in an electrolyte solution. The Z2 allows you to count and size cells between 1-200 microns, and gives absolute cell counts / concentrations.
 
The Z2 has a mercury-free metering system making it environmentally friendly, and is easily calibrated with the touch of a button. This automated calibration is done through NIST tracable standards which allows for easier use and verification. It is compact, measuring only 17.5 inches tall, by 10.4 inches wide, with a depth of 14 inches. It weights a mere 30 lbs making it a great benchtop counter. It accepts tube sizes of 200, 140, 100, 70, and 50 microns.
 
The accuracy of the Beckman Coulter Z2 falls within +/- 1% of reference, and it is more precise than 1% CV at meter volumes .5 & 1.0 ml. The user can store up to five analyses profiles and the Z2 also gives the user selectable sizing. The Z2 can measure the distribution of size in a cell population, provide graphic, size stats, counts, and also determine and count numbers falling outsize of certain sizes.
  • Constant current technology¬†eliminates calibration drift due¬†to electrolyte conductivity or¬†temperature changes.
  • The Mercury Free Metering¬†System is environmentally friendly¬†and inherently safe.
  • Recessed sample platform allows¬†sample vessels to be held safely¬†in place during analyses.
  • Small footprint for conservation¬†of valuable laboratory space in¬†today‚Äôs busy laboratory.
  • Automated calibration, using NIST¬†traceable standards, for increased¬†ease of use and instrument¬†verification.
  • Storage and automated recall of¬†up to 5 user specified instrument¬†settings (Profiles) for individual¬†cell lines.
  • Ability, using the Z2 model, to¬†average up to 10 replicate assays¬†for increased statistical confidence.
  • Acquisition,via Windows based¬†software, to the PC of both count¬†and size distribution results.¬†Available in the Z2 only.
  • Self contained, disposable¬†reagent paks enhance ease¬†of instrument use and ensures¬†convenient and safe biological¬†waste management.

    The z2 arrived within a week and looked nice and clean. They did a good job sprucing up and refurbishing this part best I can tell. Been using it for 3 months without any issue.
