Sample Cells
Model 1955 HPLC Flow Cell
With a sample capacity of 20 µL, this non-fluorescing fused silica cell is ideal for on-
line monitoring of fluorescent samples. The cell maintains high sensitivity because it
has a large aperture for collecting the excitation light to the sample and fluorescence
emission from the sample. The flat sides allow maximum throughput while keeping the
scattering of the incident radiation to a minimum. The cell fits in a standard cell holder.
Model 1923 Micro Cell (with Model 1923A Adapter)
This non-fluorescing fused silica cylindrical cell holds 50 µL. This cell will not accept a
magnetic stirrer. The 1923A Adapter is required to be able to mount in a standard 10
mm by 10 mm cell holder.
Model 1924 Micro Cell (with Model 1924A Adapter)
This non-fluorescing fused silica cylindrical cell holds 250 µL. A magnetic stirrer can-
not be used with this cell. The 1924A Adapter is required to enable mounting in the
standard 10-mm-×-10-mm cell holder.
Model 1925 Quartz Cuvette
With a 4-mL volume, this cell measures 10 mm × 10 mm in cross-section, and comes
with a Teflon
®
stopper to contain volatile liquids.
Model 1920 Sample Cell
This 2-mL to 4-mL non-fluorescing fused silica cell, capable of accepting a magnetic
stirrer, has a 10-mm path length and includes a white Teflon
®
cap that prevents sample
evaporation.
Model QC-SK Reduced Volume Sample Cell
This non-fluorescing fused silica cell is selected for samples with a maximum volume
of 1 mL. The square cross-section of the sample cavity is 5 mm. The precise imaging
capability of the excitation light focused onto the sample allows for high sensitivity.
The adapter and a “flea” magnetic stirrer are included.
