Parameters:
Pressure : up to 500 MPa
Temperature : -10…80°C
Pressure medium : Neutral liquids
Essential Features :
High-pressure liquid optical cell series U has been developed for UV/5.5 µm spectroscopy of biological systems. The cell (U103) in which the sample is enveloped in a quartz cuvette has larger dimensions thus suitable for large size spectrometer or could be coupled using light pipe outside sample compartment of spectrometer. The miniature cell (U102) in which the sample is poured directly into the cell, is dedicated for small size spectroscopic arrangements. Both cells are provided with in-cell thermocouples and have three optical windows which enables in-situ optical studies. Pressure is supplied using external pressure supplying unit such as MP series, temperature is controlled through external temperature circulator.
| Type | Pressure [MPa] | Sample volume [mL] | Sample envelope | Window type | Windows | Optical path [mm] | Weight [kg] |
|---|---|---|---|---|---|---|---|
| U103 | 500 | 2 | Quartz cuvette | Sapphire | 3 | 5 | 4.3 |
| U102 | 500 | 0.1 | Without | Sapphire | 3 | 2.5 | 0.3 |
The adoptable design of the optical plug allows user to apply other optical materials for lower pressures with different spectral range (e.g. quartz).
