VWR® Spectrosil Spectrophotometer Cells, Semi-Micro, 4x10mm, 1.4mL, 10mm pathlink, stopper - PK of 1 - 414004-059

Manufactured from Spectrosil quartz for accurate readings over the entire UV range to near infrared range.

Due to the fully heat-fused construction (no intermediate materials or adhesives) and careful annealing to remove any strain, there is no optical or physical distortion of the two optically polished windows

In semi-micro cells, the 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.

Three cover types are available: 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. Cell 414004-054 features a closed-top polymer screw cap with a silicone rubber gasket. Cell 414004-055 features an open-top polymer screw cap with a silicone rubber septum.

Note: Not recommended for use with ultrasonic cleaning.
