Details

Here is the corrected text: **Spectrophotometer Cells** Our spectrophotometer cells are manufactured from high-quality Spectrosil quartz, ensuring accurate readings over the entire UV range to near infrared range. The fully heat-fused construction eliminates intermediate materials and adhesives, preventing optical or physical distortion of the two optically polished windows. **Cell Options** We offer a variety of cell options to suit your specific needs: * **Semi-Micro Cells**: Walls parallel to the light path are thickened, decreasing the sample chamber width to 4mm. Sub-micro cells have a Z dimension that must be matched between the cell and the instrument to be used. * **Standard Rectangular Cells**: Available with three cover types: flat lid, stopper, and screw cap. Flat lids and stoppers are made of polytetrafluoroethylene (PTFE). Stoppered cells feature a block fused to the top of the cell with a ground hole for the stopper, providing a more suitable seal for volatile liquids. Cells with screw caps can be used under anaerobic conditions and offer an air-tight fit. * **Micro Cells**: Available with black sides or slides. **Cell Specifications** | Cell Type | Cat.
