These versatile instruments provide single, double or triple reactant mixing, with variable delay lines. Stopped flow, quenched flow, reactant volumes and sequence timings are all under computer control. Changes to experimental procedures can be made very quickly by a few keystrokes.

SFM stopped flow - full Computer Control

Bio-Logic stopped flow instruments use computer controlled stepping motors to drive syringes. This innovative control gives high precision rate and volume control, completely variable mixing ratios and no overpressure artifacts.

Rapid kinetic reactions can be detected by UV, CD, fluorescence, FTIR and mass spectroscopy. Also by dual detection such as CD plus fluorescence. Typical Bio-Logic experiments include:

• Protein folding
• Conformational changes
• Substrate binding
• Enzyme kinetics
• Second messenger studies

All in one stopped-flow system

The new SFM-100/MOS-LED from Bio-Logic is ideal for basic rapid kinetics research and teaching applications. Delivering research grade performance in a low cost two syringe system with low sample consumption, excellent data acquisition specifications, and a user friendly design, the unit is ideal for teaching labs or research applications.

The MOS-LED is based on Bio-Logic's long experience with LED spectrometry. Single wavelength LED sources provide an excitation signal for absorbance or fluorescence.

Benefits include:

• Fast, single mix kinetics
• Integrated absorbance spectroscopy
• Spec-Lab software
• Simple Plug and play setup
• Optional Fluorescence
• Optional motorized drive
