For an economic analysis, we deal with F Device and the OD Device separately. The reason for this is the bad comparability to commercial devices. Latter do not combine the measurument of fluorescence and OD while being in the same product class of small, portable devices. With our OD/F Device, we offer a solution to combine both measurement methods in one device. With the instructions provided by us it possible to either build an OD Device or an F Device or an OD/F Device. We are offering a high degree of flexibility by enabling the user to modify our device according to own ideas and wishes. | For an economic analysis, we deal with F Device and the OD Device separately.

- | Both portability and low cost | + | Both portability and low cost are two out of several factors that we heavily place importance on. Commercially obtainable spectrophotometers like [http://www.opticsplanet.com/unico-model-s-1205-spectrophotometer-5-nm-bandpass.html UNICO S-1205], for example, cost $1.250 or more, and can measure optical density only. On top of that, they are heavy, hardly portable and therefore not easy to handle. However, they are able to work with a broader range of wavelengths and show higher accuracy and precision. For measuring fluorescence, devices such as [http://www.moleculardevices.com/systems/microplate-readers/fluorescent-readers/gemini-xps plate readers] are available. Yet comparing a commercial device with our F Device is really difficult because we could not find one that is both portable and able to measure at 480 nm. |
- | + | To compare our device to a commercially availalbe system we chose the OD-meter [http://www.laboratory-equipment.com/laboratory-equipment/cell-density-meter.php CO 8000]. This device measures the OD at 600 nm, too, but costs almost $920. Our [https://2014.igem.org/Team:Aachen/OD/F_device OD/F Device] can measure OD as well as fluorescence for less than [https://2014.igem.org/Team:Aachen/Notebook/Engineering/ODF#diy $60] as shown in the following chart. '''Cost saving''' here is round about '''$850''', money that could definetly be invested into other research projects or equipment instead. Nonetheless, one weakness of our device is the low reliability compared to commercial devices. This is due to use of low cost materials. Prices are given in both Euro and US-Dollar for better accountability and easy conversion. | |
