2.3Features

Cuvette photometer The BioPhotometer plus is a cuvette photometer for the fast, simple and comfortable measurement of the most important methods in the molecular biology and biochemistry research laboratory. It can also be used for the main photometric methods in cell biology.

Method programs Method programs for calculating the concentration of nucleic acids, proteins and dye-labeled nucleic acids and proteins as well as the method "OD600" for calculating the bacteria density through measuring turbidity are already preprogrammed. However, you can modify those in many parameters. Other methods for calculating the concentration for 340, 405 and 490 nm can be freely programmed. The method "absorbance" is used for the fast absorbance measurement with any of 9 available wavelengths without further evaluation.

Method programs are combined into groups which you can open quickly via fixed keys.

Cuvettes You can use standard rectangular glass or plastic cuvettes with optical transparency for the respective measuring wavelength. With the Eppendorf UVette you can also measure nucleic acids and proteins in the UV range using a plastic cuvette. A cover protects the cuvette shaft against dust and other contamination if the photometer is not in use. To open the cuvette shaft it is moved back, to cover it after completing the measurements it is moved forward.

Measuring keys After opening a method the device is immediately ready for measuring. A measurement is started with one of the 3 round measuring keys.

2 Product description

Evaluation The BioPhotometer plus converts the measured absorbance values into concentration results. Dependent on the method the results can be calculated via fixed factors, standards, or curve calibration. In addition to the results the device also displays the absorbance values and some other important details, e.g. the common absorbance quotients for nucleic acid calculations. Sample dilutions can also be included in the evaluation. Other special evaluation procedures are provided for specific method groups. For example, when calculating the concentration of dyed nucleic acids the frequency of incorporation related to the amount of nucleic acid can also be calculated.

Output The BioPhotometer plus outputs the results via the device display and via a printer available from Eppendorf.

4 Installation

4.1Preparing installation

Keep the transport carton and the packing material for subsequent safe transport or storage.

Check the completeness of delivery based on the details of the scope of delivery (see

Delivery package on page 8).

Check all parts for any transport damage.

4.2Selecting location

Select the location for the BioPhotometer plus in accordance with the following criteria:

•2 power sockets with ground conductor for the BioPhotometer plus and the printer.

•Solid laboratory bench with horizontal work surface

Space requirement of the device: 40 cm (with printer: 65 cm) width, 50 cm depth.

•Temperature: 15 to 35 °C. Avoid direct sunlight.

•Humidity: 25 to 75 % relative humidity.

•Atmospheric pressure: 70 to 106 kPa.

4.3Connect device to the main power supply

1.Place the BioPhotometer plus onto a suitable work surface.

2.Ensure that the mains voltage and frequency match the details for the range of mains voltages and frequencies on the device nameplate.

3.Connect the device to the power supply and switch it on from the mains power switch 8 (Fig. 1 on p. 8).

4.Remove the protective film from the device display.

4.4Cuvettes

You can insert standard rectangular glass or plastic cuvettes into the cuvette shaft (outside diameter 12.5 mm x 12.5 mm). The optical path height must be 8.5 mm above the cuvette base and the total cuvette height must be at least 36 mm. The light beam in the cuvette is 1.0 mm wide and 1.5 mm high.

The cuvettes must be optically transparent for the respective measuring wavelength. For measurements in the UV range Eppendorf provides a plastic cuvette called UVette which is transparent from wavelengths above 220 nm and therefore also suitable for the measurement of nucleic acids.
