Sub-Micro Cells Stopper Top -volumes from 10 to 160 microlitre


Starna^®: Sub-Micro Cells Stopper Top -volumes from 10 to 160 microlitre.
Starna Sub Micro cells allow you to use very small volumes - no adaptors required! The sample is placed in a "cell within a cell" where the sample maintains a 10mm path length for maximum sensitivity. The height and width of the window is then based on the actual sample volume. For a 40痞 volume cell the window is 2mm x 2mm. All of the face of the cell is blackwith round internal cross-section All Sub Micro cells have the same exterior dimensions as a standard cell: 12.5mm x 12.5mm x 45mm high. The smaller volume means that the sample compartment must be placed directly in the light beam of your instrument. This is determined by the "Z Dimension" which is the distance from the bottom of the cell holder to the centre of the light beam. When using aqueous samples please keep in mind that the cell volume is the geometric volume of the sample compartment. Since water forms a miniscus, you must overfill the cell by 10 - 15% to ensure that the sample fully fills the window of the cell. Most organic solvents do not have this requirement. All Sub-Micro cells are constructed of Spectrosil far UV quartz. The usable range is from 170nm to 2700nm. All cells have 2 polished windows and are suitable for absorption UV/Vis spectroscopy.
