Stopped-flow /quench flow - BioLogic

Stopped-flow /quench flow.

The most efficient micro-volume, stopped-flow and quench flow solutions available on the market

The premium stopped-flow family (SFM) lies at the heart of BioLogic’s rapid kinetics instrumentation range. Based on independent stepping-motor technology, the SFM product line has been designed to achieve the shortest possible dead time, and the highest precision, in order to minimize sample consumption and accommodate the largest range of detectors.

The SFM-2000/3000/4000 stopped-flow series is available for single, double or triple mixing applications. Recognized for its versatility, the SFM is not only a stopped-flow and can convert in minutes to a freeze quench, to a cryo-stopped flow, or to a chemical quench-flow system.

For applications where sample cost is a priority, BioLogic has developed stopped-flow and quench-flow solutions that just require 10µl of solution per experiment. With a µSFM or QFM-4000, a complete series of experiments can be performed with just 100 µl in a vial saving precious time and samples without compromising sensitivity.

Instruments.

Cryogenic Stopped Flow

Cryo stopped-flow covers temperature ranges below -15°C where traditional stopped-flow experiments are limited. Cryo stopped-flow instruments are now well-established systems in inorganic and bio-inorganic chemistry laboratories where they have proved to be efficient tools used to identify reaction intermediates and define reaction mechanisms.

Freeze quench

Freeze quench can be used to study full and intermediate kinetics by trapping reaction intermediates, whose presence has been determined by stopped-flow experiments

SFM-2000, SFM-3000, SFM-4000 Stopped-flow

A range of single, double or triple stopped-flow mixing systems designed to ensure the shortest possible dead time.

µSFM

A unique micro-volume stopped-flow solution for the most demanding applications

QFM-4000

A unique design enables the QFM-4000 to trap and identify reaction intermediates. The device is also commonly used for analysing enzymatic reactionq, DNA cleavage or single turnover reactions.
