The ULP Flowcell - The new Ultra-Long Path Flowcell allows absorbance measurements through an optical path length of 50 cm (shorter paths are avaliable), with an internal volume of only 102 microliters.   The ULP Flowcell is ideally suited for very low level nutrient and trace element assays frequently required in such areas as  Oceanographic research  applications.  The cell allows VIS/NIR (400 nm to 1,000 nm) absorbance measurements.  Eliminates or minimizes the need for pre-concentrations during online monitoring.   Wetting surfaces include Fused Silica, Viton®, and PEEK.    Contains no Teflon AF.
