Classic Ambient Temperature Cell Assembly
 The classic stopped-flow cell assembly supports both absorbance and fluorescence measurements at moderate temperatures; because Teflon™ is used in the cell, temperatures below approximately 10°C are impractical.
 For fluorescence measurements, a mirror attachment is available to maximize emission collection. The mirror attachment slides over the cell assembly (as shown) such that the mirror is positioned directly behind the rear window; emissions that would be lost through the rear window are thereby reflected towards the detector.
 The optical pathlength for absorbance is indicated in purple. The optical pathlength for fluorescence excitation is indicated in blue.
The 20 mm quartz flow tube is mounted between a pair of Teflon™ end caps. A quartz window is installed in the end of each cap. Mixed reagents enter and exit the flow tube through the small holes in the end caps.
