The LWCC-5000 series are new fiber optic flow cells with a larger inner diameter of 1 mm. High UV/VIS/NIR absorbance and turbidity applications are possible with this new flow cell, based on WPI’s established liquid core waveguide technology. The result is an enhancement of sensitivity and improved limits of detection when compared with conventional spectroscopic sampling techniques. Wetted parts in the sample cell light path are PEEK, fused silica and Teflon. Optical fibers are used to transport light to and from the sample cell.


• Flowcell for absorbance and turbidity
• 50, 100 and 250 mm pathlength
• UV, VIS and NIR
• SMA 905 fiber coupled
• Continuous flow and discrete sampling



• Larger inner diameter improves baseline stability of aqueous samples
• WPI´s patented waveguide technology enhances sensitivity and improves limits of detection
• Versatile sampling accessory used in spectrophotometry for low detection limits
• Connects directly to a Peristaltic pump, WPI’s sample Injector assembly (# 58006), and the LWCC Start-up Kit (#KITLWCC)


• DNA, RNA & protein quantification
• Flow injection analysis • Colorimetric nutrient and trace metal analysis
• Drug discovery
• Process control
• Preparative HPLC analysis
