Standard rectangular cells manufactured from Spectrosil quartz for accurate readings over the entire UV range to near infrared range.

• Far UV quartz
• Wavelength range of 170–2700 nm
• Fully heat-fused construction

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 four optically polished windows

Lids and stoppers are made of polytetrafluoroethylene (PTFE). Cell 414004-057 features a closed-top polymer screw cap with a silicone rubber gasket. Cell 414004-058 features an open-top polymer screw cap with a silicone rubber septum.

Cells exhibit a transmission tolerance within 1.5% at 200nm.
