Dye laser cells (DLC) must be made extremely accurately with a surface flatness which extends to the edge of the cell. Many of the fluorometer type of cells illustrated in this catalog may be used for laser applications. However, to ensure their optical flatness, fluorometer cells must be polished to more exacting tolerances and given the prefix DLC. There are other cells specifically designed listed below. The DLC-3-Q-10 is supplied with a PTFE lid while the other dye laser cells shown in the top row are supplied with a PTFE stopper. The DLC300-Q-20 and DLC300-Q-40 are supplied without a lid.

Cell specifications:
Starna spectrophotometer cells and other quartz and glass assemblies, unless precluded by design, are assembled using a fully fused method of construction. This technique ensures that cells are fused into a single homogeneous entity using heat alone without intermediate bonding materials. All cells are then carefully annealed to remove any residual strain from the fusing process. This ensures maximum physical strength as well as resistance to solvents.

Pressure: With few exceptions, most cells can be used safely with pressure differentials of up to 3 x 105Pa (3 Bar) and some up to10x105Pa (10 Bar).
