The touch-screen user interface of the DU Series 700 spectrophotometers provides
easy access
to system functions, and application parameters can be optimized quickly and
easily. User
programs or methods can be defined and permanently stored. These customized
settings
can be quickly recalled and applied. Data can be stored temporarily in the
system and after
the run sent to the attached devices, such as printer, PC, or memory device.
System Setup & Optimization
- Storage and recall of up to 50 User Programs or Methods
- Automatic or manual storage of data with recall
- Automatic lamp turnoff after a user-specified idle time,
individually for UV and Visible source
- Peripherals, such as printer, keyboard, and memory device
are automatically detected
System Checks (Performance Validation)
- Software upgrade via memory stick
- Lamp History and Reset
The following diagnostic tests are included:
- Wavelength Accuracy and Bandwidth
- Photometric Accuracy and Reproducibility
- Photometric Noise
- Stray Light
- Drift (Stability)
The system comes with a 1 cm Single Cell Holder. The transport mechanism for the
7-position
Carousel is built-in. Cell holders and modules are available for a variety of
applications to ensure
that you can obtain optimal results from your samples. The cell holders as well
as the modules
can be interchanged quickly and securely.
Cell Holders
- 1 cm Single Cell Holder (included with each system)
- 16 mm Test Tube Holder (built-in)
- Carousel Cell Holder with 7 positions for 1 cm cuvettes, including
semi-microcells
- 50 µL Microcell Holder
- Turbidity Cell Holders for 1 cm cuvettes
- Multi-Cell Holder can accommodate cuvettes of different sizes (1, 2, 5
cm rectangular
cuvettes as well as 1 inch round and rectangular)
Peltier Temperature Control Module
- The module ensures that each sample, which should be
contained in a 1 cm quartz cuvette, is measured at the specified
temperature
- Ideal for enzyme kinetic experiments and when accurate
temperature control is required
- The module is specified for a temperature range from
15°C to 50°C (59°F to 122°F)
Sipper Module
- For quick and convenient measurements of multiple samples
without the need to transfer samples to cuvettes
- A peristaltic pump draws the liquid into the flow cell; the
instrument takes a reading and returns the liquid to the source
or discharges it
- The Flow Cell has a volume of 350 µL and is included
together with an appropriate tubing kit. The Single Cell Holder
or the Multi-Cell Holder can be utilized with the module
