Chirascan™
SF.3 Stopped-flow accessory
|
The SF.3 is a dedicated stopped-flow accessory for the Chirascan circular dichroism spectrometer. The SF.3 accessory brings to Chirascan our world-leading expertise in stopped-flow design to enable circular dichroism (CD), absorbance and fluorescence stopped-flow measurements of unsurpassed sensitivity. The unit is based on our best-selling SX20 and PiStar stopped-flows, and designed to enable rapid and straightforward coupling to Chirascan: a roller-plate mount enables it to be easily located and locked into place at the exit slit of the Chirascan monochromator (in place of the sample chamber unit). |

A demountable stopped-flow cell provides optical pathlengths of 2mm and 10mm and has a dead-time of 1.5ms. Cells can be changed in a few minutes; a smaller, lower dead-time, cell is available as an option. Circular dichroism (CD) and absorbance kinetics are collected using the standard Chirascan detector. Fluorescence detection is also possible with option TF.3. |
