As standard, the DS5 comes with a touchscreen for standalone operation controlling all modes of operation: photometry, time scan, wavelength scan, and data analysis including calibration curves.
Additionally, Visacle® PC-controlled software enhances your DS5 experience by offering comprehensive control, validation, data analysis, and reporting—all in one streamlined package. With Visacle, your data is securely stored in an organised database, ready for analysis and easy export in .txt, .csv, or PDF formats.
For those needing extra security, Visacle is available as a CFR Part 11 compliant package. Key features include:

The DS5 covers the UV range down to 190 nm with an absorbance range > 3.
This makes measuring samples high UV absorption possible, such as the edible oil spectra plotted below.

The standard cell holder is two-position and holds traditional 10 mm path length cells. A micro-volume cell holder option for 50 μl cells is also available.
Designed for incubation or temperature stabilisation from room temperature to +40°C. Temperature stability ±0.3°C.
Designed for low concentrations or absorbance, the long path cell holder holds two rectangular cells with an optical path length of 10 mm to 100 mm.
Designed for measuring the transmittance/absorbance of glass samples or filters. Sample dimensions up to 55 mm x 100 mm with 5 mm thickness can be accepted.
Designed for measuring the transmittance/absorbance of thin-film samples. Sample dimensions up to 25 mm x 50 mm can be measured.
Mount up to six standard 10 mm path length cells with auto-changeover of sample. A temperature controlled version is also available.
Designed for rapid and automatic measurement of multiple or large amounts of liquid sample without changing cells.
Designed for continuous measurement of trace samples. Flow cell capacity of 70 μl, 10 mm path length with Teflon tubing.
