3/I/40 - Macro Standard Rectangular Fluorimeter Cell. Open top, with non-sealing PTFE cover

Standard rectangular fluorometer cells Type 3 are the most popular cells for general fluorescence measurement and they will fit virtually every fluorometer instrument. All four windows and the bottom of the cell are polished and because of the technique used in their construction they remain extremely flat, right to the very edge of the window, allowing them to be used in some laser applications. Each cell is supplied with a PTFE cover.
