2.3 Features

The BioSpectrometer basic is a UV/Vis spectrophotometer for measuring liquids in cuvettes in a wavelength range of 200 nm to 830 nm. It is intended for use in development and research in the fields of molecular biology, biotechnology, biochemistry and cell biology. Glass and plastic cuvettes in a volume range of 1 μL to 3000 μL can be used.

2.3.1 Methods

Numerous methods for concentration determination of nucleic acids, proteins, and dye-marked nucleic acids and proteins, and the OD 600 method for determining bacterial density via turbidity measurement, are already preprogrammed. Furthermore, method templates for various measurement and evaluation procedures (single and multiple wavelength measurements, taking spectra, evaluations with factor, standard and standard curve) are preprogrammed. It is possible to create individual methods on the basis of the preprogrammed methods and templates. The templates in the Absorbance method group can be used to quickly measure absorbances or spectra without an additional evaluation.

2.3.2 Operation

The preprogrammed methods and templates are combined into clearly arranged groups from which the desired method can be quickly selected. After calling up the method, you are guided through the measuring procedure in clear steps. A help box in the display provides hints upon request. The 3 round measuring keys (standard, blank, sample) allow users to quickly start a measurement.

2.3.3 Result output

The BioSpectrometer basic outputs the results using the device display and a printer available from Eppendorf. With a USB connection, you can transfer result data from the device to a USB stick, a printer or directly to a PC.

2.3.4 Device self test

The device automatically tests the function of the spectrometer unit right after it has been switched on. Access the Device calibration function for a more comprehensive test (see Device self-test on p. 73).

5.2 Inserting the cuvette

Standard rectangular glass or plastic cuvettes can be inserted in the cuvette shaft:

• External dimensions: 12.5 mm × 12.5 mm

• Height of light path: 8.5 mm higher than cuvette base

• Total height: min. 36 mm

The cuvettes must be optically transparent for the respective measuring wavelength. For measurements in the UV range, Eppendorf offers the plastic cuvette UVette which is transparent for wavelengths of 220 nm and higher and therefore also is suitable for measuring nucleic acids.

5.3 Summary of the measuring procedure

5.3.1 Preparing the measurement

1. Switch on the device and, if required, the printer.

The device performs a self test (taking approx. 1 minute) and displays the method selection.

2. Make ready the cuvettes for the measurements (see Inserting the cuvette on p. 24).

3. Prepare the measuring solutions for measuring the blank values, if required, also the standards and the samples.

4. Open the cover of the cuvette shaft. The cover can remain open during the measurements.

You should not use any measuring solution for standards and samples with a lower absorbance than 0.02 to 0.03 A (e.g. dsDNA concentration between 1.0 and 1.5 μg/mL). The detection limit of the device may be significantly lower, nevertheless, the impact of disturbances from the measuring solutions (particles, bubbles, turbidity) on the reliability of the result is very high for these low absorbance values.

5.3.2 Measuring procedure

5.3.2.1 Selecting a method

 Use the cursor keys to select the desired

method and call up the method with the enter

key. For an overview and a detailed description of the methods, refer to the next chapter (see Methods on p. 31).

Wizard: The wizard at the top of the display will take you through the method procedure step-by-step. Help box: You will receive help texts in the lower right of the display during each step of the procedure. Softkeys: The [< Back] and [Next >] softkeys allow you to move between method steps in the wizard.

5.3.2.2 Checking parameters

5.3.2.3 Measuring the blank and standards

 Check the parameter setting. The [Page dn] and

[Page up] softkeys allow you to call up the

parameter list pages. You can modify and save

parameters using [Edit].

For evaluations without standards (e.g. DNA measurements), this method step is omitted.

1. Start by measuring a blank (blank key).

2. Then measure all standards one by one

(standard key). The display always marks the standard that is to be measured next. Use the [Graph] resp. [Table] softkey to change the result view.

 Press [Next] to accept the evaluation calculated

from the standard results.

5.3.2.5 Finalizing the method

Operation

Eppendorf BioSpectrometer

basic

English (EN)

 The sample key is used for measuring your

samples consecutively. Blank results will remain saved for the duration of one series of measurement. However, a new blank measurement always is possible. (The adjacent figure shows a measuring procedure with evaluation via the standard curve and, in addition to the sample result, the graph of the standard evaluation.)

5.3.2.6 Optional: process results

1. Press [Finish], to complete the measuring series

and return to the method selection.

2. After all measurements have been completed,

switch off the device and close the cuvette shaft

cover to protect the cuvette shaft from

contamination.

For some methods, you can postprocess the results in the process results method step. For example, you can use the SpectraZoom zoom function in the spectra.

 Use the and cursor keys for selecting

systematically any results of the series of

measurement for postprocessing.

5.3.2.7 Printing and exporting

1. Compose data packets for all samples or for

selected samples.

2. Print the data, save them to a USB stick or

transfer them to a PC via a USB cable.

5.3.3 Important measurement instructions

Check for each measurement:

• For plastic cuvettes: How many consecutive measurements can be reliably carried out in the cuvette?

• Measure the cuvette blank value before the sample or standard measurements in order to compensate the cuvette blank value in addition to the reagent blank.

• Blank results remain saved for one measuring series, but a new blank result measurement can be performed at any time, even between sample measurements.

• The displayed absorbance values always correspond to the directly measured values. The dilution or cuvette factor as well as background absorbances only will be incorporated for the following result calculation (see Absorbance values on p. 89).

• The measuring result is typically displayed 2 to 3 seconds after a measurement has been started. If (for high absorbance values) only a low quantity of light reaches the receiving part, the measuring time automatically can be extended to 9 seconds in order to increase the precision of the measurement.

• Observe that the measured absorbance values do not exceed the upper limit of the photometric measuring range. In this case, reject the measuring result. The upper limit of the photometric measuring range does not only depend on the wavelength (see Photometric properties on p. 86) but also on the cuvette blank. Ultra-micro cuvettes with a small diaphragm, such as TrayCell (Hellma), may have a cuvette blank of approx. A = 1. The available photometric measuring range is reduced by this amount. You can estimate the cuvette blank by measuring the cuvette filled with demineralized water as a sample in comparison with the empty cuvette shaft as a blank. The cuvette blank of the Eppendorf μCuvette G1.0 is negligible (approximately A = 0).

• After the measurement, remove the measuring solution completely before filling in the next measuring solution in order to minimize carry-over. If a carry-over from one sample to the next sample can be expected due to a high concentration difference, rinse the cuvette between the measurements.

• If the temperature between the lamp and the ambience differs, photometric drift may occur. Therefore a device from a colder ambience first has to be adjusted to the ambient temperature.

Avoid quick changes of temperature. Carry out a new blank measurement for a long series of measurements or measurements over a long period of time.
