2.3 Features

The BioSpectrometer kinetic 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, acquisition of spectra, kinetic methods, 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 kinetic 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 checks the function of the spectrometer unit and thermal module immediately after it has been switched on. Access the Device calibration function for a more comprehensive test (see Device self-test on p. 72).

1. Position the cuvette so that the optical window of the cuvette is pointing towards the direction of the light path.

2. When inserting the cuvette, press it completely to the bottom against the slight resistance.

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. 21).

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.

5.3.3 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 a small amount of light reaches the receiver, the measuring time automatically can be extended to 9 seconds in order to increase the precision of the measurement. For kinetic measurements, the automatic extension of the measuring time is not applied in order to prevent any conflicts with the preprogrammed interval time for the measuring point recording.

• 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.

5.3.4 Notes on working with cuvette temperature control

Temperature control is regulated using a measurement on the cuvette holder. The temperature in the measuring solution may deviate from the temperature on the cuvette holder.

The extent of the deviation is dependent on the measuring volume, cuvette material, cuvette shape and ambient temperature. The temperature control speed is also dependent on these factors. The temperature control of plastic cuvettes is slower compared to glass cuvettes. The surface of the cuvette in direct contact with the wall of the cuvette holder should be as large as possible to ensure quick temperature control. Therefore, the temperature control of plastic semi-micro cuvettes as well as, for example, the UVette is only performed slowly.

Operation

Eppendorf BioSpectrometer English (EN)

• For efficient temperature control, the volume of the measuring solution in the cuvette should not project beyond the edge of the cuvette holder.

• To speed up the measuring procedure during series measurements, you can pre-cool cuvettes with reagents in a thermostat outside the BioSpectrometer before inserting the cuvette in the cuvette holder and adding the sample.

• When switching from a method with temperature control to one without temperature control, please note that the temperature of the cuvette holder will slowly drift back to room temperature. The results of the method without temperature control could be affected by this.
