Ohaus VXMPDG *NEW* Vortexer

Ohaus VXMPDG *NEW* Vortexer

Cambridge ID #: 20246


OHAUS Microplate Vortex Mixers are perfect for mixing microplates throughout the speed range. All models are designed for continuous-duty use in the lab. Digital models offer a timer and exact speed control for applications that demand repeatable results and non-digital variable speed models are an economical alternative. The high-speed and small orbit of these mixers make them optimal for effectively mixing microplates.


ELISA Assays, PCR Preparations, Digestions, Cell Disruptions


Independent LED displays for speed/time allow the operator to view both settings simultaneously (digital models) and adjustment knob with dial markings for variable speed control (analog models)


Detachable 3-wire cord and plug (included)

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.



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


Performance Specifications

  • Mercury Free
  • Sample result averaging
  • Size distribution graph and tabular data
