Bioscreen CTM
Automated
Microbiology Growth Curve Analysis System
Bioscreen-C Automated Microbiology Growth Curve Analysis System directly measures microorganism growth. As microorganisms grow, they increase the turbidity of their growth medium. By measuring the turbidity of this medium over time, an optical density (O.D.) curve can be generated. The curve reflects the growth (increased concentration) of the organism of interest.
Bioscreen-C Analyzer Components
The organism of interest and any growth medium are manually dispensed using a multichannel pipette into wells of a special honeycomb microplate. This 10 x 10 well plate is designed to provide a uniform temperature across each of the 100 wells in the plate. A fitted plate lid with special characteristics eliminates troublesome condensation and evaporation, which often interferes with O.D. readings with conventional 96-well plates.
Bioscreen-C Analyzer
The instrument has a unique incubator incorporating a liquid circulation heat exchanger, which provides constant temperatures to all wells. This is essential for developing high quality growth curves. It also includes a linear shaker to assure good mixing in each well.
It has a sensitive reader that measures turbidity, a technique more sensitive than a spectrophotometer. The reader is also equipped with 8 filters to measure specific wavelengths. Two covered honeycomb plates may be run at one time, making it possible to run 200 samples simultaneously.
Turbidometric measurements are made kinetically during the course of the run. Data is exported to a PC, and subsequently processed to generate growth curves, plotting O.D. vs. time.
Software
Bioscreen EZ Experiment software is provided free with the system. It drives the instrument and records results. All experimental data (O.D., test parameters, sample names, growth curves, and results) is exported to the PC, running Windows 2000 or Windows XP. Excel software may be used for tabulation of data, creation of growth curves, and preparation of reports.
