Other Stopped-Flow Options
Listed below are some of the numerous options available with the KinetAsyst Stopped-Flow system:
Additional Detection Methods
Dual Channel Fluorescence Detection
Permits the reference photomultiplier to be used as a second detection channel (OPT-687).
Dual Detection Accessory
Allows simultaneous absorption and fluorescence measurements (OPT-686).
Fluorescence Emission Scanning Option
An option where the monochromator can be used to resolve the fluorescence spectral emission while using bandpass and interference filters to maintain high levels of excitation intensity (OPT-679).
Fluorescence Polarisation Accessory
Enables the direct reporting of fluorescence anisotropy and polarisation. Includes pair of filters to be specified (OPT-661).
KinetaScan™ Rapid Scanning Diode Array
Allows the acquisition of high resolution, homogenous spectral data from a single shot (MG-6560).
Circular Dichroism Attachment for Jasco J-700/800 series instruments including control unit
Enables the acquisition of circularly polarised data using third party optics (OPT-648).
Conductivity Stopped-Flow Cell Assembly
Facilitates the study of kinetic systems which do not contain chromophores or fluorophores (OPT-642)
HI-FLOW Low Volume Cell
Optimised for fluorescence measurements up to 2000 s-1 (5 μl volume, 0.5 ms Dead Time) (OPT-689)
qPOD™ Quench Flow Attachment
Allows the conversion of the sequential mixing system to a simple quench-flow unit where the user can recover aged, quenched samples (OPT-647)
Additional Light Sources
Visible Light Source (Tungsten) 340 – 800 nm (OPT-612)
Deep UV Absorbance Option (Deuterium) 200 - 360 nm (OPT-622)
Combined 75 W Mercury/Xenon Lamp (tube only) (OPT-671)
Low Temperature Option
CANTERBURY™ Single Mixing Cryo-Stopped-Flow Option (down to -90º)
Provides a single mixing low temperature option. A short umbilical connection replaces the standard cell block on the primary instrument and connects the reagents to a LN2 cooled cryo unit with submerged flow circuit and observation cell. Configured: stand with PEEK lined stainless steel reagent lines, 10 mm path via a pair of fibres compatible with photomultiplier and diode array detection (single beam only). Designed to be used with a wide range of solvents, especially where water and oxygen should be excluded.
(OPT-658)
LN2 Delivery Unit. Comprises 25 litre liquid nitrogen Dewar and pump (OPT-658A).
Extra Fibre for Fluorescence Window (OPT-658B).
Pair of Extra Fibres for 1.5 mm Path (OPT-658C).
All Stainless Steel Flow lines (no PEEK). Others by request (OPT-658D).
Miscellaneous Options
Anti-Photolysis Shutter
Allows the study of photosensitive systems in both absorbance and fluorescence modes (OPT-667).
High Ratio Mixing Option
Allows multiple syringe delivery (asymmetric mixing) of reagents in single mixing mode. Includes two syringes (OPT-669)
Circulator and Cooler
Suitable lab circulator for temperature control of sample handling unit (OPT-655).
Thermostat Kit
Comprises thermostat jacket and dry gas purge connectors (for temperatures below 15oC) (OPT-630).
Anaerobic Options
A comprehensive range of options ranging from the use of tonometers to incorporation into a glove box are available to facilitate studying oxygen-sensitive systems.
