Remote Fiber Optic accessory Sipper accessory The Remote Fiber Optic accessory allows you to take the measurement at the sample rather than taking the sample to the instrument. It is ideal for remote, non-destructive testing of fluorescent papers and fabrics as well as the sampling of hazardous materials such as radioactive sources. A Sipper accessory is available for those laboratories that would like to automate routine analysis and quantitation. It automatically moves the sample from your sample vessel to the measurement cuvette, and minimizes the need to handle and clean quartz cuvettes....
